i'm trying to wash rocks. i'm terrible. i'm taking a whole amount of days already. all i've been doing it putting hot water on them. i thought it was the best this i could do. just today, though, i found this spray stuff that i remembered using it to clean the rocks. but it can damage your skin and stuff, and i can't find anything to put on my hands to clean them. am i doing it right? how do you guys clean rocks? thanks MIKE
