Dude it's wax lol. Tap it??? lmfao hahaha if you don't wash it it'll just mottle up later on, mannnnn big brands giving the wrong info. You HAVE to wash it. Soapy water I think is best, but I'm just popping my two pads in with my terry cloth towels with a little washing power in the washing machine. They're fine man. No problems. This might be bad though lol, so ask Chompies or Silva. I could be an idiot and not know it lol Thanks :) That's what I thought too...yah...It doesn't make sense not to wash them...as you said they would become dry and that would scartch the car when you use it next time.... Maybe the professional don't wash them because they use it everyday, and wouldn't have time to dry.... Thanks for your info, and hopefully Chompies or Silva can see this and give some comment on it too. :)
