Deceptive appearances – “clean” can be infectious

Woman with magnifier
Just because it’s clean doesn’t mean it’s germ-free

You can’t see germs, they’re too unbelievably small.

You can tell when they’re around though – the smell of something “off” or the discolouration of growths like mould.

And of course, the swelling round a cut, or the queasiness in your tummy.

Hungry to eat – you

They’re hard at work, doing the only thing they know how – eat. And it’s when they eat you, that you start feeling sick.

So the thing is, to stop them before they get the chance – a constant war against them, even though they’re invisible.

Uh huh.

But we’re surrounded by billions and billions of germs, all the time – mostly bacteria. They’re even inside our bodies, living in harmony – doing useful work, like help us digest food.

There’s still billions more, some good, some bad – tuberculosis for example is a very unpleasant experience. There’s viruses too – also not so good for us – unable to function properly without a warm human body. And all too ready to bring us down.

It’s because of germs that we have to keep cleaning things – not just that they’re yucky. They’re dangerous and infectious. (Tweet this)

We see the dirt, we rub or scrape it off, rinse away any residue – and assume that’s good enough.

Germs never give up

Except that germs are much more pernicious than that. And when you get down to microbial levels, what you think might be a smooth surface isn’t smooth at all. It’s like a rocky mountain range, with plenty of rocks and crags to hang onto.

That countertop you’ve just wiped down might LOOK clean, but could still be infested.

OK, we’re aware of that, which is why we use germ-killing cleaners like bleach. Oxidising action destroys the germs, so we’re safe.

In theory.

But like we said, germs are pernicious – and persistent.

Scrub, scrub

Was the bleach solution strong enough? Was it there long enough to kill everything? And didn’t you have to wipe it off afterwards, so remaining bleach couldn’t contaminate anything?

Chances are, only half the germs got clobbered – and anything else you wiped could have picked them up too – that wiping cloth is a double-edged sword.

Right, so it’s rub-scrub-wipe, rub-scrub-wipe all over the place – work surfaces, furniture tops, floors – and hopefully it’s safe. It certainly looks sparkling – a few hours well spent.

Well yes, but germs don’t just sit on flat surfaces, they’re everywhere else too – the walls, cupboard doors, the ceiling, behind things, underneath, and in every nook and cranny.

Oh yes, and the air of course – it’s 80% of the room space. Floating, swirling, drifting, hovering – so small and light they may never fall to the floor. Billions and billions of them, ready to catch on your skin or clothing, or for you to breathe them in.

Aargh! What can you do?

The Don’t-Wash-Hands Disease

For a start, wash your hands. You use them for everything and most germs spread on contact. So if they’re on your hands, they can transfer to everything you touch. Infectious, infectious!

Wash Hands Logo
Your personal everyday defence against germs

Like the soft tissue round your eyes, nose and mouth – because, would you believe, most of us touch our faces 2,000 – 3,000 times a day!

Want to know how nasties like norovirus get to you most of the time? From germs on your hands in contact with all kinds of things – other people, common objects, or believe it or not, from the loo. Your hands are infectious.

Which why, in this blog, we refer to it as the Don’t-Wash-Hands Disease.

So what about the rest of the job, all those nooks and crannies? And how in the world can you scrub the air?

Total room steriliser

The easy answer is with a Hypersteriliser.

You’ve done the main work and got rid of the dirt and gunge. Now comes the follow-up to do everything else – and to destroy ALL germs completely.

Press the button and the Hypersteriliser generates an ultra-fine mist of hydrogen peroxide – quickly filling the place like the bathroom when you’re having a shower.

It’s no ordinary mist either. This stuff is ionised, with highly charged electrons all trying to escape each other, pushing in all directions to get away. This forces them everywhere – up, out, underneath and behind, deep into cracks and crevices – as far away from each other as they can get.

The same charge attracts them actively to fixed or floating cells of viruses and bacteria. They grab hold like a magnet, shoving atoms of oxygen at them – ripping their whole cell structure apart.

No germ survives this oxidising action. They are dead and gone – the whole place is sterile.

And the hydrogen peroxide? Without its charge any more, it reverts to oxygen and water – and an ultra thin, infinitesimally wafer-like layer of silver – used as a germ-killing booster and left behind as a protective antibiotic coating.

Yes, everything looks clean – and now the germ threshold is zero. No bugs anywhere, except the ones you might bring in with you.

And they’re no problem either – you HAVE washed your hands, haven’t you?

Why wipe-clean won’t wipe out killer germs

Professional cleaners
A world of difference between clean and safe

Powerful stuff, chlorine bleach.

Strong enough to blow the top of your head off.

“Kills all known germs dead,” as the famous Domestos claim said.

And it does.

If you use it properly.

Take that, horrible germ

Except none of us do.

Because there’s one heck of a difference between cleaning and disinfecting. (Tweet this)

Most of us bung some bleach in a bucket of water with some detergent, grab a cloth and wipe away at everything we see that looks dirty.

Everything we SEE.

But you can’t see germs. They’re too small.

Something like salmonella or campylobacter – easily present in uncooked meat, particularly chicken – are only around 5 microns across. Small enough to fall THROUGH an unglazed earthenware plate.

Both are likely to be found on your chopping boards or kitchen counters – spread around all over the place in any drops of water from washing food  beforehand.

Uh, huh. So doesn’t the Domestos or kitchen surface cleaner get rid of them?

Depends on how you use it.

Wipe clean is not enough

If like most of us, you spray and then wipe, getting rid of all the dirty marks – probably not.

Because strong though the germ-killers you are using might be, they need TIME to work.

Usually 2 minutes or more – what the manufacturers call “dwell” time. And if you’ve already diluted your bleach before you start, you should allow even more – a weaker solution needs longer.

Ah, but we don’t do that most of the time do we?

Bleach is pretty potent, we know it attacks all kinds of surfaces if we leave it. So we tend to wipe it on, then dry it off quick with a paper towel.

Not good, Jim.

The stuff needs time to work, plus it ought to be sluiced off. You don’t want traces of bleach getting on to the food that you’re preparing. You could make your whole household very ill.

Also, if you think about it – your wiping cloth gets less potent the more you use it.

Whoops. That can actually make things worse.

Germ spreaders

Not enough time to kill the germs. And actually TRANSFERRING germs to other surfaces.

Pretty bad, hey?

Now imagine the same in a school or restaurant kitchen – professional catering setups serving to hundreds of people. Get salmonella or campylobacter running loose in that lot and you’ve got big problems.

And those are just two of the viruses or bacteria nasties that could be lurking there. There are billions more possible.

Not just on the counter tops or chopping boards either.

In the cracks between the counter and the splashback. Down the front of cupboards and storage lockers. In the gaps between the cookers and the fridges. In and around the edges of things. Under the sink and table surfaces. On the walls, on the floors. The ceiling too.

Oh yeah, and in the air too. Where most of them are. Around 80% of the room space. Where your wiping cloth won’t reach.

Hungry pathogens, hanging around everywhere.

If there’s food around, bacteria will go for it. Not as nice as a warm human body, but stick around, somebody might get careless. There’s plenty to eat in a missed grease spot or gravy spill. So it’s only a matter of time.

Which is how – even in kitchen of the best restaurant in the world – germs can breed and multiply, eventually triggering multiple infections with everyone wondering why.

Safe, secure, sterile

Far better to treat cleaning and disinfecting as separate jobs – and doing both properly.

Cleaning, by eye as usual, is good enough to start.

Followed up by disinfecting every single surface and the air itself. Or even better, sterilising everything.

Impossible, right? It would take an age to wipe all those surfaces, if you could get to them all.

But that’s exactly what a Hypersteriliser does.

Without touching anything – no transfer from one place to another – it mists up an ionised cloud of hydrogen peroxide that spreads everywhere throughout a room and oxidises “all germs dead” in around 40 minutes.

Safer than bleach? You bet, your own body produces hydrogen peroxide to kill infection whenever you get a cut or skin puncture. Oh, and when it’s done killing germs, it reverts back to harmless oxygen and water.

Just get out of the room while it’s working, it can make your eyes and throat a little uncomfortable.

Spreads everywhere?

Forced diffusion

More like a power dispersal.

Because it’s not just hydrogen peroxide mist. Ionising it turns it into a plasma, a kind of super-gas.

In the nozzle of the Hypersteriliser machine, ultra-fine molecules of hydrogen peroxide are charged by high voltage electricity. Each with the same negative charge, they are naturally – and aggressively – repelled from each other. Remember magnets at school?

Spreading as far away as they can get, they fill the room quickly, forcing themselves hard up against everything they touch – and underneath, on top, behind – everywhere they can get. Deep into cracks and crevices too – actively trying to escape from each other.

Bad news for cells of viruses and bacteria, lurking on surfaces or floating in the air. Remember magnets again?

With an opposite positive charge, the hydrogen peroxide molecules are violently attracted to them. They reach out and grab hold, welding themselves together – which causes extra oxygen atoms to be released, ripping into the viruses’ and bacteria’s DNA, destroying their cell structure, making them dead.

Effortless, easy

And all without lifting a finger.

No grunt work, scrubbing and wiping. No overpowering smells. No germs anywhere.

The whole place is sterile.

So now you know wipe-down doesn’t always work, how long are you going to keep doing it the old way?

Why normal sterilising is just not good enough

Woman doctor in mask
Safe isn’t safe
until it’s 100% sterile

However you look at it, the job is a schlep.

Seems any sterilising effort needs stinky chemicals that give you a headache and strips away paint if you’re not careful.

Bleach, formaldehyde, peracetic acid – don’t think for a second that any of that stuff is good for you.

Not nice, however you do it

Either that or it’s heat so hot, you can’t stand it.

Or messing around with ultra violet light and exposing yourself to whatever.

Or worst of the lot, you’re playing around with some noxious gas that does your head in with the slightest whiff.

On top of which, you’ve usually got to scrub like crazy before you get anywhere. Then wash the whole lot off afterwards.

Strictly for the birds.

Like ordinary washing, but nastier.

Still basically manual wipe.

Which means how hard you scrub, and for how long, also comes into it.

Plus, how can you be sure you haven’t missed a bit?

And how about all the surfaces you can’t normally reach? Like underneath things? Or behind? Or on top? And all those wires and tubes for the equipment you use? Computer cables, screens, keyboards, phones?

Get liquid in any of them and BGRZAPF! Things stop working.

And what about the air? All that room space around you?

Less than perfect, the job’s not done

So whatever you try, 80% of the germs around you don’t even get touched.

And those bugs are sneaky – just about nothing stops them.

Like the Streptococcus mitis bacterium we came across in yesterday’s blog. Coming back to life after two and a half years on the moon – surviving launch, space vacuum, radiation exposure, deep-freeze at 20 degrees above absolute zero, with no nutrient, water or energy source.

Miss one of those things with your squidging sponge and you’re right back where you started.

OK, so technology can help a bit.

Like, bung everything in an autoclave – if you can find one that’s big enough. Fine for instruments, but a bit difficult with a whole room full of stuff.

Ultra violet

Then there’s an American company which has this robot thingy that zaps out ultra violet light. Kills all germs dead in minutes, job done.

Well yes, but we have a similar machine and it only works for line of sight. Any obstruction that the light rays can’t get to the back of remains untreated. And the dose gets weaker, the further you are from the machine.

A good idea, but you’ve got to work at it. Move it around a lot so the light rays get everywhere. Like we said, those bugs are sneaky.

All right, how about gas? It gets into the air, spreads around behind things, surely that’s the answer.

Ozone

Things don’t get much more potent than ozone, a kind of super-oxygen that kills all viruses and bacteria stone-cold dead – the same stuff that high up in the atmosphere protects the Earth from the sun’s deadly radiation.

Uh, huh. But to be effective, its concentration level can be very hazardous. Mild doses are fine for taking out smells and getting rid of mould. But even then, the place has to be evacuated and you’ve got to vent it out thoroughly before it’s safe to use the room.

Vaporised wetness

Sticking with airborne ideas, fogging up the place is another method that is often tried – usually with hydrogen peroxide, a powerful oxidiser, just like ozone – but a lot more people-friendly.

Water-based, the problem is getting the stuff to disperse efficiently. The vapour is heavier than air and takes time to reach everywhere. It’s also wet and needs to be dried off after treatment. Drip, drip into electrical connections, also a hassle. And again, the concentration level necessary makes it hazardous to work with.

How, how, how, to get rid of all the difficulties?

Ionised efficiency

Check out the Hypersteriliser machine. Round the world, hospitals, clinics and care centres are beginning to hike sterilising hygiene to a whole new level with it.

Yes, it uses hydrogen peroxide – but ionised, so it’s finer than air and spreads better – electrically charged so it actively reaches out and grabs viruses and bacteria on the fly.

It’s also boosted with colloidal silver. And remember? Way back before antibiotics, it was silver compounds that were the first choice in dealing with infections.

In fact silver sulfadiazine cream was the standard antibacterial treatment for serious burns until well into the 1990s.

Better still, silver’s antibacterial properties get dramatically enhanced by an electrical field – exactly what happens to it in the nozzle of the Hypersteriliser.

So it’s not just hydrogen peroxide misting out – it’s a Twenty-First Century germ-killer that takes sterilising a whole quantum leap into vastly more effective protection. (Tweet this)

There’s no schlep either. Just press a button and it works itself.

A bit better than a sponge and bleach – but stick around. We’ll always need spot sterilising as a failsafe.

Hospital: Keep Away!

Prison phone
Hospital visiting hours –
except it’s not a crime to catch a bug

It’s the double-edged sword of antibiotics. We can’t live with them – and we can’t live without them.

Because just about every surgical procedure there is relies on antibiotics to prevent infection.

And alarm bells are ringing. The number of pathogens resistant to antibiotics is growing.

20 years for a cure

Faced with a new Dark Age, medics are pushing for research into more effective drugs. But proper development and testing can take 20 years.

Humanity can’t wait that long.

We need something now – a higher level of hygiene in everything we do.

But nobody says it’s easy. Even sterile measures can introduce infection to surgical procedures. Particularly post-op – less easy without the rigorous scrub-ups, sterilised instruments and dressings,  or the HEPA (High-Efficiency Particulate Air) filtered airflow.

Which brings us to the Big Q.

Quarantine

Isolation.

A UV tunnel at all entrances to kill surface germs. Continuous deep clean and scrub down with effective germ-killers like formaldehyde and bleach.

Better still, with airborne hydrogen peroxide which destroys every virus and bacteria it touches.

The downside is, it’s mostly the patient who is the source of infection – an existing condition, or brought in on their person when admitted.

So are visitors. You yourself are a source of infection too. Strip naked and power-shower, you’re still a threat to anyone with open wounds.

So are hospital staff. Germs surround us wherever we go, it’s a fact of life.

Sterile is not enough

We can sterilise the hospital environment – the air, the beds, the equipment, the wards – but we can’t sterilise the people.

Which could mean out with the hazmat suits – for visitors and hospital staff.

Or visiting granny could get more like visiting prison.

On the phone, behind plate glass. Patients in no-go areas. No physical contact.

To keep you safe. To keep them safe.

Except being sick is not a crime. Nor is catching some nasty bug.

Of course it won’t happen. We’re not that inhuman.

Don’t take chances

Unless we get an epidemic. Like in 1918, when flu took out a third of the planet and killed 50 million people – almost the population of Britain.

Makes you think, doesn’t it?

Forget to wash your hands five years from now – and maybe you won’t come back.

Let’s be careful out there.

Norovirus: how to stop repeat outbreaks before they start

Norovirus misery
Being sick is bad enough, even worse with a norovirus repeat, over and over again. Photo by Sydney Sims on Unsplash

Norovirus, ugh! Not only does it feel like the end of the world – seems nothing can stop the dreaded repeat outbreak.

Repeat, repeat and repeat – it boomerangs back and back again. Highly contagious, seriously pernicious – despite the most meticulous deep clean procedures.

Which either means it really IS impossible to beat. Or whatever we’re doing to stop it simply isn’t good enough.

Harsh truth when a thorough job usually involves ripping the place apart. Head-blowing bleach stink with hard scrubbing everywhere for hours – and STILL the bug comes back again.

Know your enemy

Yes, but norovirus is no ordinary stomach bug. It’s the ultimate survivor.

For a start, it only takes ten microscopic particles of the virus to start an infection. Compare that with flu, at maybe between ten and forty times that – and you’re looking at a much more vicious enemy.

Vicious is right.

It’s also why norovirus is so violent – crippling cramps, projectile vomiting and explosive diarrhoea.

Exactly right to spread itself as far and wide as possible – the widest opportunity to start new infections with any newcomers who unsuspectingly chance along.

Plus of course, it might only infect on contact – but it DISPERSES through the air.

Well sure, each particle is barely 2 microns across – light enough to ride the air currents in any room for hours or days. Breathe in just ten of them through your mouth, swallow – and chances are you’ll be hanging onto the loo in utter misery, just 12 hours from now.

And those horrid upchucks?

Yes gruesome, but think of how far they reach and spread.

Across the impact area on the furniture and floor, obviously. Exactly the right place to move in with mop and bucket. But how about underneath? Or behind?

And those are just the big gobs of stuff.

How about the individual particles swirling around – settling everywhere or still riding the breeze? Reach those with sponge or squeegee too?

Wipe down the surfaces, yes – but how about in the coils of power cables, or down the back of electronic equipment? How about the sheets of paper lying on the nearest table – the first thing to be removed by unthinking hands?

The floors get scrubbed. The walls too. Every surface is rubbed down within an inch of its life.

But seldom underneath. And seldom in those hard-to-reach places that nobody thinks about. Cracks, crevices – tiny places where a 2 micron particle might survive for weeks on end.

Which means deep clean or not – the infection never went away in the first place.

Start using the room again, and those norovirus particles are only too ready to come out and do their thing. Not gone. And certainly not forgotten. Repeat, repeat and repeat.

Not good enough

And anyhow, how effective is the stuff we’re using?

That bleach solution might be strong enough to rip your head off, but how does it stack up against a survivor like norovirus? A wipe with even a concentrated solution won’t crack it – to kill norovirus, bleach has to be in continuous contact for at least TWENTY minutes.

So even though a surface is treated, it still might not be safe.

Same thing with steam.

You can give yourself a nasty burn if your not careful. But to kill norovirus, even that kind of heat takes TWO minutes of constant contact or more to do the job. Like bacteria, viruses can survive in the frozen Antarctic, or live happily in a seething volcano. What’s a little steam bath, now and then?

And how are you applying it? With a waving hosepipe?

Well, yes. Because if you did apply superhot steam to everything continuously for two minutes, it would be sodden through and probably useless – shorted out or fused, if it’s anything electric.

And have you seen what bleach does to surfaces with prolonged contact? Shrivelled up or corroded very quickly.

Which puts us where? Hours of work down the drain and the bug still present. Repeat, repeat and repeat.

We think we’re safe, but norovirus is just biding its time. Ready for its repeat performance, just when you thought it was safe.

Money, money, money – not just health

Don’t worry, we’re not the only ones. How about an expensive investment like a cruise ship? Hundreds of passengers, sick and ready to sue.

Thousands down the drain and STILL norovirus comes back – like Fred Olsen Line’s Balmoral, struck down SIX times since 2009.

Or Holland America Line’s Caribbean cruise liner Amsterdam – having to cancel four trips in succession because of repeat outbreaks in 1982.   It got so bad, the ship had to be taken out of service to ensure thorough decontamination – and new passengers were even warned before embarking that the ship had previously had problems it couldn’t get rid of.

All of which says, if you want to get rid of norovirus, there’s no pussy-footing around.

Conventional cleaning just won’t work. And that’s all it is anyway – cleaning.

It’s not actually sterilising – making germs dead, so they can’t infect anything.

Repeat, repeat and repeat

The job’s not done and norovirus is still lurking.

OK, so get unconventional.

Think killing germs, not just cleaning.

Especially getting to the airborne stuff that never gets treated anyway. Yet 80% of pretty well every room we live in is nothing else!

You can throw technology at it, like ultraviolet radiation – that will at least do something.

But there’s a downside to that too. Light can’t go round corners, unless you have lots of mirrors. So blitzing a room with UV means either a lot of exposures in different positions – or manhandling great unwieldy pieces of shiny metal (glass would break).

Oh and yes – a variation on the contact time. The potency of UV as a germ-killer falls off rapidly with distance from the light source. Unless everything’s within about ten feet, those pesky norovirus particles won’t be cashing in their chips just yet.

Which leaves fogging.

Like the insect control people do when they fumigate a house – pump a load of germ-killer into the air and let it swirl around. The usual choice is hydrogen peroxide, an effective germ killer and less toxic than most alternatives.

But also fraught with a few problems.

Just getting it into the air doesn’t make it reach behind, underneath or on top of things. There’s nothing to push it into cracks or crevices either.

It will kill the germs alright, norovirus included. But without effective dispersal to reach everywhere, there’s still nothing to prevent repeat outbreaks.

And just consider fogging the place up with a vapour. Lots of moisture to play havoc with sensitive equipment and paper. Enough that a second machine is necessary alongside the fogging one – to dry everything out after the vapour has done its work.

Plus there’s the old question of contact time. As a vapour the stuff is heavier than air, so doesn’t stay airborne long.

To compensate, a strong solution is necessary – 32%, about the maximum permissible without being totally toxic. Yes it kills, but it’s also pretty corrosive – not good on plastics or sensitive surfaces – and certainly not good for computers.

So what, repeat norovirus outbreaks are inevitable – even with technology?

The RIGHT technology

Depends on the technology.

Because it IS possible to mist up the place with a safe solution of just 6% hydrogen peroxide. And have it spread everywhere by ionising it – so it tries to escape from itself, yet reaches out and clamps hold of germs as it does so.

Contact time is less than 2 minutes – because ionising changes the stuff into a plasma, which multiplies its oxidising power several times over. Forty minutes tops, and the whole place is sterile – no germs anywhere, not even norovirus – repeat or no repeat.

OK, yes, this a blatant plug. But if you’re as sick of one norovirus repeat after another as we are, you’ll be glad to know there’s a system that works.

And not just on norovirus either – on everything.

Your way of giving germs the same dirty treatment they give you.

One hint of health risk, and your whole business reputation nose dives

Nose dive crash
Taking chances – when the wrong germ comes along, your whole world goes for a loop

One germ is all it takes. One teeny microbe less than 0.002 microns across – and there goes your reputation.

E.coli is it?

A customer ate something that disagreed. Food poisoning headlines in the local press. All over TV and Facebook. Wisecracks on Twitter making it worse.

A reputation nightmare.

OK, so things happen. Somebody makes a mistake and the whole organisation pays for it.

Or not.

Because e.coli is a germ you can catch anywhere. Off a doorknob or a product display. Off the handle of a customer basket. From a handshake with sales staff. Out of the air. Anywhere.

Same scenario with most germs. From mild colds and tummy bugs to life-threatening illnesses.

Picked up on contact, or breathed in.

The blame game

So are you unlucky – or genuinely negligent?

Dirty hands are a cause, most of the time. They look clean but they’re not – at least not since after breakfast. And hands touch everything, including mouth and nose – the germs’ way in to reputational mayhem.

The customer’s hands, or staff’s?

With reputations on the line, it’s unwise to point fingers.

Most people don’t wash their hands from one moment to the next. Especially breezing in off the street. But you can’t accuse them, even if their hands are crawling. 0.02 microns is impossibly small to see, even if there are millions of them. So it’s you who’s accused – of insults.

On the staff side of course, you can see it coming.

Take precautions and be ready, before anything happens.

Minimise the risk

Like tighten up on staff hygiene. When hands are washed, how thoroughly, and how often. When latex gloves get used. How merchandise is cleaned and presented. Nannying detail yes, but your reputation depends on it.

Likewise, how your whole place is cleaned.

Not just a lick and a promise, but properly sterilised. If there’s no germs anywhere, you know the e.coli must be the customer’s.

And properly doesn’t mean bleach. The smell alone will drive your reputation away all by itself.

Besides, how’s bleach going to reach all the places that germs are more likely to lurk? In dark corners, away from the usually scrubbed counters and work surfaces? Or in the air itself?

No, no – to get rid of germs, you’ve got to get serious. Just like your reputation is serious  – and e.coli makes bad PR.

So it’s sterilise or nothing – again, your reputation depends on it.

No germs on anything anyone might touch – staff or customers. Including all the things nobody ever thinks about but uses all the time. Like self-service touchscreens and lift call buttons.

Bring on the tiger

Time to think ionised hydrogen peroxide.

And a nifty all-automatic machine – the Hypersteriliser.

It’s loaded with a mild 6% solution of hydrogen peroxide – the same germ-killer stuff you can get in Boots as antiseptic. And the same stuff our own bodies naturally produce to fight infections from cuts or scratches.

Ah, but press the button – and you waken the sleeping tiger.

IONISED, see. Which mists the hydrogen peroxide into a dry superfine spray – and transforms it from a gas vapour into a plasma.

Yup, you’ve got yourself a tiger. Because now that mild 6% solution releases a slew of other antimicrobials – hydroxyl radicals, reactive oxygen species, reactive nitrogen species, ozone and ultraviolet – every one, a germ predator.

Plus the ionising forces the tiger out of its lair and actively on the hunt. Forced apart electrostatically to disperse aggressively in all directions. Fiercely pouncing oppositely-charged bacteria and viruses -and clawing them to shreds by oxidising them.

Not kind. But think of it this way. It gives germs the same deadly treatment they give you. Or more appropriately, your reputation.

Give it 40 minutes or so, depending on room size – and the whole place is sterile. No germs anywhere. In the air, on any surface, in any tight inaccessible places, or in any cracks, crevices and remote corners.

OK, so with the whole place germ-free, any e.coli floating around has got to be the customer’s.

But you know how it goes, you get the blame anyway. Benefit of the doubt and all that – the customer is always right.

Roar of approval

Uh huh, so your final play is to protect the customer from herself.

Before she has a chance to touch anything, offer her antibacterial wipes or gel – free with your compliments.

Well it’s your reputation, so what’s she going to think – free hand wipes AND the whole place sterilised for HER health and security?

Wow! Worth paying a bit extra to shop there, don’t you think?

And how’s it going to look for you when she climbs on Instagram and Snapchat to her friends?

Like we say, it’s your reputation. And with the tiger on your side, you’re playing for keeps.

Luxury right now – but one day soon, ALL hotel rooms will be germ-free

Relaxed exec
Luxury, but you’ve earned it – the right to be germ-free for a good night’s sleep

Imagine. Open the door – and your room not only welcomes you, it’s completely germ-free.

You’re flaked out, ready to crash – so you know your system is weakened.

But no, you’re not going to come down with anything – your room is safe enough to relax properly AND let your guard down.

Forget the paracetamol for a start. Your body doesn’t need it, there’s no need to take precautions. If the symptoms start showing, you’ve picked something up BEFORE walking in here. Because right now, you should be absolutely safe.

Germ-free – a new level of luxury

So. No viruses, no bacteria – as you can tell from the smells.

That’s right, there aren’t any. Except maybe from the flowers to welcome you. The chocolate on your pillow. And the exotic soap, still under cellophane in the bathroom. Nothing else though – like the tell-tale pong of bacteria at work.

Luxury? Or the way things should be?

Hotel rooms are cleaned every day, so they SHOULD be germ-free. But as any experienced traveller will tell you, they very seldom are.

Inevitable really.

All the right things are done – the vacuuming, the wipe-downs, the clean towels and linen. With disinfectant and air freshener too.

But hotel rooms are high use and high turnover. There’s no time and it isn’t practical to do a deep clean for every guest. Not even 5-star VIPs.

Ouch! Bleach

Bleach does the job, but needs exposure time to be effective. At least 30 minutes at fair concentration – except it leaves a stink and makes your head woozy.

And whoever’s going to use liquid bleach on light switches, bedside phone  or TV remotes? The things will short circuit and never work again. That’s IF cleaning staff don’t electrocute themselves in the process.

Or how about the other high touch areas?

Door handles, the dressing table, bedside units, bathroom vanity slab, or the floor in the shower cubicle?

To do all those in the turnaround time between room check-out and the next guest arriving just isn’t possible.

Or getting to any of the other fixtures and fittings that SHOULD receive attention. The bedspread, the curtains and the carpet, for instance. Nine times out of ten, they get left till the end of the month.

Pretty well all germs are airborne and contaminate new areas that way. The physical dust might be vacuumed out of the carpet pile. But there’s the collective germ-load of every single guest since the last steam clean still lurking there. Exactly why experienced guests never take their shoes off.

And anyhow – how do you clean the air itself, spray bleach around? Half the fittings will shrivel up or corrode – and your head will feel like a brain transplant without anaesthetic.

Twenty-First Century easy

Old technology. It doesn’t have to be this way.

Remember life before smart phones? Unthinkably primitive now, how did we ever survive?

Same thing with getting rid of germs. The new push-button technology does the job in a jiffy. Well, in the 20 minute jiffy it takes to spread out through the air, find all the germs, and send them to oblivion.

Get used to seeing a new house-keeping addition in the corridor as you head for late breakfast . After a fabulous night’s sleep with no travel gremlins – not even air conditioning sniffles.

There’s the linen trolley and the cleaning cart and the vacuum cleaner. And a nifty mobile console alongside about the size of a small wheelie-bin – the Hypersteriliser.

There’s your luxury revolution right there – the high-tech way to make hotel rooms germ-free.

Once all the cleaning is finished, that thing mists up the place with ionised hydrogen peroxide and takes out all the germs. ALL of them.

Tiger, tiger

Bit of a sleeping tiger, that whole procedure.

Because by itself the hydrogen peroxide is a pussycat – the same eco-friendly 6% solution you can buy in the chemist. As an antiseptic or for bleaching your hair. The same stuff our own bodies produce for fighting infections.

Ionising catapults it into a whole new dimension. Sprayed out in a dry superfine mist, it transforms from gas vapour into a plasma. A complete change of state that releases  even more germicidal high performers – hydroxyl radicals, reactive oxygen species, reactive nitrogen species, ozone and ultraviolet.

That pussycat is now a giant-size and riled-up, super efficient predator – all claws and fangs.

Ionising also triggers its hunting instincts – aggressively dispersing away from itself in all directions, driven by electrostatic charge. That same charge seeks out and pounces on oppositely-charged viruses and bacteria. Oxygen atoms claw them to pieces.

Game over.

99.9999% safe

And that’s ALL germs in the air, on ALL surfaces, behind ALL objects, underneath ALL objects – and burying deep into ALL cracks and crevices – ALL hunted down and annihilated. 99.9999% of ALL germs gone – to a 6-log Sterility Assurance Level.

Total effort involved, pressing a button. Time taken, 20 minutes or so, depending on room size. And all that’s left, oxygen and water – in such small quantities it evaporates immediately.

Oh, and a microscopically thin layer of colloidal silver on everything. A further and lasting barrier protection against germs. So that room is sterile immediately, or stays that way as long as it’s closed – for up to a week or more.

Sterile room – yes, luxury.

But fast becoming a necessity in this jet-age world of ours – where virulent infections from the other side of the world are suddenly on our doorstep, courtesy of direct flight Boeing 787 or Airbus A380.

So it’s not just colds and flu that hotels are fighting against. It’s the whole alphabet soup of MERS, SARS, HIV/AIDS, MRSA and all the other nasties. So easily caught by touching a cushion or a room service menu. So easily neutralised by daily letting the big cat loose.

No viruses, no bacteria, no parasites, no fungi – that tiger really earns his stripes.

Now deadly superbugs resist disinfectants too

Biohazard team
Disinfect all you like – once germs resist, nowhere is safe

It’s our own fault really. Teaching bugs how to resist. Believe it or not, by having a go with disinfectants too often.

Too often, or too carelessly?

Because bacteria are survivors, see? They’ve been on this planet longer than any other living thing. So they can cope with extremes. Acid environments, polluted with metals.  Even boiling water.

Which makes resisting disinfectants a bit of a doddle.

Slap-happy routine

Especially when disinfectants come at them every day.  Routine same-old, everybody’s used to it – plenty of slap-happy mistakes.

Not properly applied, so bits get missed. Not strong enough, so not all are killed. Not exposed for long enough, so even more escape.  And always repetitive, so they know what’s coming.

More of the same, get ready. And not all of them are dead from last time.

Not dead, and not driven out –  every time they get stronger. Better able to resist. More used to defending themselves.

Plus, if it gets too hard to resist, they get clever.

Like going up against bleach – the one substance bacteria has a problem with, because it oxidises them.

But not a problem if the bleach is too weak, or not left on for long enough.

Billions of years of being clever

A couple of capfuls in a bucket of water makes a solution that’s not nearly strong enough. And the usual wipe-on, wipe-off won’t leave it there nearly long enough – bleach takes 30 minutes exposure time to be sure of a kill.

Plus, bacteria can live with the smell, even if we humans can’t. The rest is just outlasting the stuff. Ensuring there are enough bacteria around to keep going.

Not a problem when you can regenerate yourself quickly. E. coli for instance – including its deadly O157 variant – can replicate itself every 20 minutes.  If a batch get wiped out, they’re easily back at strength in just hours.

The other trick is to hide behind biofilms – hard-to-remove slime that protects bacteria from contact with the bleach.

Or to unfold a heat-shock protein, Hsp33, which binds and protects other proteins from harm, helping the bacteria to survive.

All of which means, if you’re going to disinfect something, do it properly.

Life’s a bleach – or not

Use bleach, slap it on thick and leave it there for 30 minutes or more. Not always that simple as bleach attacks metals, particularly stainless steel. Your nose will tell you it’s pretty corrosive to other substances too.

Otherwise, you’re teaching the bacteria to resist. Giving it an immunity to further disinfectants used against it in the future. AND teaching it antibiotic resistance as well.

Or there is an easier solution – which no bacteria can resist, no matter what. No viruses or fungi either.

Simply mist the place up with ionised hydrogen peroxide.

Electrostatically charged, the stuff reaches everywhere. Including the air, which never normally gets touched, even though it’s 80% of the average room space. And forced hard up against all those hard-to-reach places your sponge or cleaning cloth can’t get at.

Like bleach, the action is by oxidising. But exposure time is 30 seconds, not 30 minutes.

Because boosted by ionising into a plasma mist, hydrogen peroxide releases a slew of other other antimicrobials. Hydroxyl radicals, reactive oxygen species, reactive nitrogen species, ozone and ultraviolet.

Oxygen atoms reach out and grab at germs, ripping their cell structure apart.

40 minutes later, and it’s done and dusted. Disinfected AND sterilised.

The mist reverts to eco-friendly oxygen and water, which evaporates – and the whole place is germ-free. 99.9999% gone – no bacteria, no viruses, no fungi – to a 6-Log Sterility Assurance Level.

No slopping around on top of the necessary rubbing and scrubbing. No noxious fumes either.

Hard to resist?

You bet.

How under-powered disinfectants can actually create superbugs

Pointing to biohazard symbol
Make that disinfectant solution too weak – and you’ll make it antibiotic resistant, sure as anything

Kill germs. Make you safe. It’s what disinfectants are supposed to do.

But only if you let them.

Only if they’re at full strength – and applied for full contact time.

Maximum bleach, flat-out for 30 minutes. Complete exposure.

None of this diluted and sloshed around with a wet rag nonsense.

Resistance in the making

Anything less than full power and there are germ survivors.

Maybe not many of them, but they are the toughies that win through.

Hit them again and they’re less likely to succumb.

They’ve learnt how to resist, mutated to become immune.

Bacteria for instance, have in-built protein pumps that expel toxic substances from their cells. “Efflux pumps” to remove disinfectants AND antibiotics, making bugs drug-resistant.

And how dangerous is that?

OK, so there is a work surface, perhaps for food prep. Wiped down for 30 seconds with a usual 6% bleach solution, everyone thinks it’s disinfected, safe.

Instead, it’s alive with MRSA – methicillin-resistant staphylococcus aureus.

Already resistant to antibiotics, it easily resists to the under-dose of bleach.

Too weak, not long enough – did you feel a breeze, just then?

Not good enough

So now it’s resistant to bleach too – sodium hypochlorite.

Or maybe chlorhexidine – the preferred disinfectant for instruments. Which in its underpowered state can trigger resistance to colistin – an antibiotic of last resort. As discovered by researchers investigating klebsiella pneumoniae – a superbug capable of causing pneumonia, meningitis and urinary tract infections.

Uh huh. So somebody comes down with MRSA – redness, swelling, pain and high temperature.

They have to be isolated to keep others safe. Quarantined in a separate room. Only handled with gloves, apron and mask for protection.

And OK, the food prep area is suspect – so it’s done again.

More 6% solution – more thorough this time, wiped down and scrubbed for 5 minutes.

Still not enough.

MRSA still in residence – along with a few other bugs it’s passed on its immunity to.

Resistant to bleach and antibiotics too.

Last resort defences breached

Like carbapenem-resistant enterobacteriaceae (CRE) – unlikely in the everyday, but possible in hospital.

Dangerous?

Oh yes.

Carbapenem is the other group of our last-resort antibiotics. The ones to use when all else fails. If they don’t work – and colistin too – the poor patient is up a gumtree. Only clever doctors and the very best care can bring them back.

Meanwhile, that food prep area is still unsafe.

Scrubbed raw, it still contaminated with MRSA.

Still a place for other bacteria to learn how to survive first bleach, then antibiotics.

How antibiotic resisdtance happensAnd now it’s too late.

Flood the place for hours in 100% bleach solution – that MRSA still knows how to overcome it.

However strong the treatment, anything made up on that food prep area will still be contaminated. That MRSA is there for keeps.

Unless of course, you change the rules.

Game changer

After the rub and scrub, mist the place up with ionised hydrogen peroxide (iHP).

Because NO GERM can survive being ripped apart by oxygen atoms. Which is what happens in the 30 seconds that electrostatically-charged iHP particles physically grab hold of bacteria, viruses and fungi, oxidising them to oblivion.

And that’s only a 6% solution too. But ionised to hundreds of times the firepower by becoming a plasma. Releasing other antimicrobials – hydroxyl radicals, reactive oxygen species, reactive nitrogen species, ozone and ultraviolet.

No rub and scrub either – the stuff disperses in actively all directions, forced apart by that same electrostatic charge. Through the air, hard up against all surfaces, deep into cracks and crevices.

Not just disinfecting, but sterilising. Making ALL GERMS dead. 99.9999% gone – to a 6-Log Sterility Assurance Level. No bugs, no superbugs, no nothing.

Under-strength disinfectants – that’s really playing with fire.

There are enough superbugs already resistant to antibiotics. We don’t need any more.

How to get a sure-fire norovirus ALL CLEAR

Chef highsigns OK
No norovirus, or any other germs either – they’re ALL gone – the difference between clean and safe

Dead dodgy, norovirus is. Keeps coming back whatever you do. So getting an All Clear is a mission.

It doesn’t have to be.

Once the first level clean up is done, it should be quick and easy.

The trick is to be thorough.

Norovirus is adept at spreading itself as wide as possible to secure its survival.

Microscopically safe – or not at all

Getting rid of it has to be equally thorough. Not just treating surface areas, but everywhere.

Right there is why so many clean-ups fail.

If things look fresh and scrubbed, we think they are. But norovirus is a germ not even 2 microns across – a ten thousandth the width of a human hair. Against threats that small, judging by appearance is useless.

So is thinking that ordinary rubbing and scrubbing will do the job.

Yes, it’s necessary to get everything disinfected and clean.

Remember how violent norovirus is though? How it makes people double up in pain before convulsing with puke? Projectile vomiting, that’s called – one of the many ways norovirus spreads itself.

So tiny – and so forcibly ejected – it rides the air maybe 100 feet from where it started. Swirling on the smallest drafts or swish of movement, it’s carried even further- lighter than the air molecules around it. Sometimes staying airborne, sometimes settling as far away as it can get, working its way into the most microscopic cracks and crevices, determined to survive.

The ultimate survivor

And survive it does. Inside our bodies for as long as two weeks after we’ve started feeling better.  And outside our bodies for even longer.

Which means, miss a bit when cleaning – and norovirus comes roaring back just as everybody thinks it’s all clear. On top of which, it’s extremely potent – which why the National Geographic calls it “puked perfection“. Only 10 particles are enough to infect anyone, versus 4 times that for most other pathogens.

So miss just the remotest area – and you’re going to get it!

OK, so getting rid of it needs something with the same kind of spread-everywhere dispersal of norovirus itself – and that kills quickly. Something that reaches the outer limits – plus into all the nooks and crannies – without losing firepower in doing so.

Which right away rules out bleach. Sure, it’s potent enough to do the job – but you have to dilute it first – otherwise, it’s so strong it’ll do YOU damage. Say 10 tablespoons to a gallon of water is usual – that’s barely 6%. And to work at that strength, it has to be in contact for 30 minutes or more – if you can somehow squeeze it into all of those tiny cracks.

It rules out steam too. To be effective, steam has to be in contact for at least 2 minutes  at 121⁰C – not good with sensitive equipment or electrics – and soaking everything around it in the process. And germs LIKE warm damp.

Gone in 30 seconds

But 6% is exactly right for another high-powered germ-destroyer – ionised hydrogen peroxide (iHP). Deliver it in contact with any germ, and all it needs is around 30 seconds. The do-able ALL CLEAR .

6%? 30 seconds? We’re kidding, right?

Well, no – because it’s ionised. Forced to change its state from a gas to a plasma by a neat mobile dispensing unit called a Hypersteriliser.

Ionising hits three crucial objectives, bullseye.

One, it charges every particle of hydrogen peroxide, driving it to escape from itself. This forcibly disperses it, spreading in all directions and ramming itself hard against everything it comes across.

Two, only 6% in strength, its molecules are also tiny, equally able to ride the air. They force themselves into the same cracks as the norovirus – which can run, but it can’t hide.

Three, ionising turbo-boosts that 6% to hundreds of times the firepower. By releasing other antimicrobials – hydroxyl radicals, reactive oxygen species, reactive nitrogen species, ozone and ultraviolet. Less than 30 seconds contact time? Prepare for some very dead norovirus, cells ripped apart, utterly destroyed.

Allow about 40 minutes for the hydrogen peroxide to disperse fully, eliminate ALL germs (not just norovirus) and safely revert to oxygen and a small amount of water, which evaporates. Now vent the room, open the windows, turn on the fan, or simply let everything dissipate.

Time for that ALL CLEAR. And that pesky norovirus is not coming back either.

ALL CLEAR, safe and secure.
