Drysol
"I've always had clammy hands but about six months ago I had an unrelated surgical procedure, and once I recuperated I realized I was sweating a lot more than I used to from my hands feet and armpits. I went back to work and I was so embarrassed to wear regular button-down shirts because of the pit stains. I saw my dermatologist who recommended Drysol. It burns like hell but I can tell you right now that it is working for my pits I haven't applied it to my hands yet I will be trying that tonight."
