Apparently the guy was worried as his job gets his hands pretty dirty/oily and he said it repels the dirt and wipes clean. I doubt sweaty palms would be a problem. We would have heard by now if juice/sweat etc. was staining it from people who own them, and I haven't heard any complaints.
People here are great at sharing that kind of stuff!
Good to hear.
But this is what I was worried about. I'm not sure if his is an isolated case.
