Can I remove oil-based paint from furniture with paint stripper and pressure washer?
A stripper gel is worth a shot. Never tried myself. I'd definitely use a heavy duty respirator with that stuff. A big no way on the pressure washer ;).

You might also try contoured sanding pads. I use these all the time. Sanding just sucks and takes devotion..
