Does hand soap stop working after a long time of not using it?!
Question: Yes or no, why or why not?
Answers: Yes or no, why or why not?
It does work, and the reason is the only thing that's been lost is water. Everything else is still there. As a matter of fact some people unwrap soap bars and leave them out to dry up on purpose. The idea is the dried up bars last longer because they don't melt away as fast.
I'm not sure what you're asking. You cannot build up a "tolerance" for hand soap no matter how often you use it. Antibacterial hand soaps have ingredients that kill germs on your hands as well as ingredients to help loosen dirt from your skin. If you are asking how long hand washing works, the short answer is that as soon as you have touched a non-sanitized surface you run the risk of picking up germs. Often germs like the cold virus spread by touching an opening (eyes, nose, mouth) after getting germs on your hands. That's why you should be careful about washing your hands before you eat.
