WAGG is alcohol based and

shouldn't stain.

I was one of the original testers before WAGG was generally released and believe the warning

on the bottle to only apply on clothing is more for law suit protection than anything else. You can always try a

small dab on your skin to see if it bothers you. It didn't bother me and I've worn it on my skin many times. That

isn't a recomendation, simply a statement that I have personally done it with no ill effects but you have to take

the risk for yourself if you decide that you want too.
