Don't use a solvent to get it off. If you do, it will stain the wood and there will be no way to get it off. I've gotten it off before by using a coarse grit sandpaper like a 100-120 grit and sand the stuff off lightly. It will ball up and plug the sandpaper, but it's pretty easy to get it clean as long as you don't press hard while you're sanding.
