Even if it evaporates, not all of the chemicals in there will, there will undoubtably be some residual chemicals that cannot, CANNOT, be healthy. Isopropyl Alcohol is legal, it's freaking rubbing alcohol. Just go to your local pharmacy or drugstore, hell most big-box stores probably carry it.

Also, I don't know what either nail polish remover and rubbing alcohol will do to finishes on wood pipes and the like. I have no idea if it starts to deteriorate or not, and don't want to find out by it happening to my pipe. Never endanger your paraphernalia if you can avoid it... treat it like your own flesh and blood.
