Dwight, if it is "paint", then paint remover works, but is tough on wood at the same time. I like the environmentaly friendly orange colored stuff at wally world. Not as tough, put it on with a toothbrush and after 10 minutes rub on it. Less is better, but more than likely it will make them look almost new...
