Stripping altoids tins Answered

You can burn off the paint with a propane torch or gas barbaque, but the result isn't necessarily any better than you started with. Better to cover it with paint or stickers?

Heat (propane flame) and a wire brush. Added benefit of annealing the metal for repose. Why do you want the paint off?

Meths? Caustic soda (lye)? (would have thought paint-stripper would work)

pound it with a hammer? that always solves every problem for me

Try boiling it in white vinegar. You may want to do it outside though, unless you don't mind your house smelling like a pickle farm. when you are done do a rinse in baking soda and water.

Dremel device? I think someone did it for the YAN9VUSB project.
