Which is a better bacteria killer? Bleach or hand sanitizer which contains 62% ethyl alcohol.

i'm not sure but i think is the hand sanitizer.

hand sanitizer

ok thanks.

What kind of germs? What temperature? In any case, I think bleach would be hard to beat but I have no proof of that. Of course, one can't wash their hands in bleach. Ouch! The sanitizer companies advertise that ethyl alcohol, the priniciple ingredient in hand sanitizers (usually with skin softeners and emolients added) kills 99% of germs. But bleach, especially chlorine bleach, is a disinfectant. Do a little research and consult other resources before you make a decision.
