I had to remove big globs of pine sap from my girlfriend's car's windshield the other day. She didn't have denatured alcohol so I figured I'd try nail polish remover... a.k.a. acetone. That worked pretty well on the sap but I don't think it worked as quickly as denatured alcohol. As such, next time you have a sappy mess on your saws maybe borrow nail polish remover from your girlfriend or wife. It will look good sitting on your manly workbench and prove you are self confident.
