Sticker Residue...

[BigLew]

Acetone will almost always work. It is the active ingredient in nail polish remover. We used to use it at WM to remove all sorts of adhesive residue. Xylene(sp?) is nasty stuff and requires neoprene gloves, if you're smart! Also, there is Tyolene (paint brush dry paint remover) and is even more aggressive to your skin.

Just be careful and get plenty of ventilation and NO open flames!
