Does hydrogen peroxide stain skin?
Welllllllll, hydrogen peroxide is used by cops to detect meth amphetamine manufacturing. If you are a meth cook and you don’t wear gloves ( and sometimes even if you do), if you pour hydrogen peroxide on their hands, they will turn yellow. Once the meth cooks realized that this was going on, they figured out that washing their hands with lye, e.g. red devil lye, it would remove the yellow from their hands. So yes, I think hydrogen peroxide would probably leave a spot depending on a lot of things, and will go away on it’s own, probably within a week. If you want it gone now put some lye in a little water with the cotton ball and see what happens. I hear that it burns like hell when they wash their hands in the lye so be careful!
