Answer to Question #4163 in Microbiology for Alfred
I was wondering if there's a way I can kill every germ (including "super-bugs") on my hand? And if so, how I can do it? And if not, why not? One microbiologist said I can kill every germ on my hand, by lathering my hands in soap, rinsing them with warm water, re-lathering them in soap, rinsing them with warm water again, wiping them dry, and then rubbing them vigorously with hand sanitizer. I was wondering, is that really true?
I do not think that you can really kill all germs with the procedure described. You see, that procedure intended to clean hands, not to kill germs (soap, water and even sanitizer are not harmful to many bacterias and viruses). Thus, the hands will be very clean, this is true (because you wash germs out), but some germs will remain in deep layers of skin. If you want to KILL (not wash out) germs on hands, you should use another methods, like heating hands up to 200-300C, or washing them with strong acid or oxidizing agent. But the hands will be destroyed too.. In general, resistance of germs is much, much bigger than resistance of your hands, thus, you cannot kill germs without destroying your hands...
