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.
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.
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.
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?
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.
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.
