Old English from Wallymart. Works on metal, wood, and leather.
I bought an old frozen Stanley model 82 cabinet scraper this morning. Completely covered with paint.
Used paint remover, soap and water, and Old English; the wingnut adjustment and the scraper clamp are loose and working like new. I let it dry another day or two, and I'll treat the wood, perhaps with a little stain, and it will be sweet, better than it has been in 50 years.
