We tried all manner of chemical strippers. In a phrase, what we got for our efforts was a big mess every time. And no matter how careful we were, these harsh chemicals either ate whatever we wore for gloves, or, in the case of one water-based “stripper,” failed to burn our skin but also failed to release anything but tired topside paint.
DeWalt offers a great heat gun, and Sandvik sells expensive but highly effective and super-tough scrapers. We now remove all sorts of finishes without the gooey mess, without burning our skin, and without leaving chemical residues in old mahogany and oak.
