acetone does not evaporate cleanly -- it leaves a residue behind.

isopropyl is wood alcohol. It's poisonous to humans. (see: BETTY FORD). Unless you can gaurantee complete evaporation, this could literally make you blind, or worse.

I've read (sorry can't cite the source) that iso and other "denatured" alcohols are processed with additives that are toxic to humans. This is to get around the taxes levied on consumable alcohol, since alcohol that is not for human consumption is not taxed.

Carbon tetrachloride evaporates more cleanly than acetone, but it's toxic to handle or breathe.

Don't even think about the various ethyl glycol solvents, such as used to be common in antifreeze. These molecules are similar enough to be taken up as alcohol by your tissues (mainly liver), but are dissimilar enough that your body can't process them. So they're in your innards forever -- for looong after they kill you.

Play it safe -- use food grade solvents or known friendly chemicals like butane!
