Stop sign clean up?

What is the best solvent for removing spray paint from stop signs?  Would mineral spirits or acetone work? Would a quick coat of car wax help prevent future spray from sticking?

Acetone is best, but test it on a corner of the sign, because it might take the "official" paint off as well.
