Is it ok if the rp is wet with acetone when i add acid to boil it? And do i dilute the hcl(currently 31%) before i add it? This is for cleaning off matches.

Why can't you wait for it to completely dry? You in some sort of hurry or something? Got an appointment?? Ehhh...ehhh?? Just kidding. I would let it dry then kind of chop it up some. And Oh yeah, Switrd doesn't dilute it when he does it. He uses acid when he's recycling it from a past rxn. Sometimes, bits of his charmin plug stick to the rp.
