There are approximately 5,000 germs on your hand at any given time
At any given time, a human hand may contain as many as 5,000 germs.
Sanitation methods clan and reduce germs on the surface but do not kill the germs. That's why it is very important to read the labels on all your cleaning supplies, because on most of them they're two sets of directions one is for disinfecting (which will kill most germs) and the cleaning which doesn't kill any it just removes the dirt.
Nothing. Germs have to be bad germs and have to get into you to harm you.
To be fair, a lot of soap, shampoo, bleach products etc. do get rid of 100% of germs, except they can't can't possibly tell because the germs left over from something that says "Kills 99.99%" or "99.9% of germs" are too small to see beneath microscopes or any technology that has been invented. So therefore there is no specific best soap brand to get rid of germs.
