How do you remove indoor paint from the marble tiles around your fireplace?

Look for an organic paint remover. If you use thinner it will damage the finish on the marble. If its oil base paint you might not have any choice but to refinish each tile. Your best bet is an organic paint thinner, and non abrasive scrubbers, plastic or nylon. No metal or copper. Scratches the marbles surface. nhbt2 There are some strippers that you can use that do not hurt most marbles. I know of one for sure that works. The stuff is pretty mean and can eat away at your skin if you come in contact with it. It is called DADS VARNISH and PAINT REMOVER. As with anything that you put on the surface of natural stone it is a good idea to try in an inconspicuous area. To see if it will do damage to the surface. Now another way to remove spots would be to take a straight edge razor blade and scrape it off. The only problem with that is that if you use the blade for to long it will develop burs on it that can scatch the surface. NEVER EVER turn the blade over and use the other side. To be on the safe side do a small area with the blade then throw it away. Marble is a pourus surface, so if the paint was spilled it could soak into the stone and I would use the stripper instead of the razor blade.
