u sure it's paint? I'd try a heat gun. but that looks like limestone. limestone is very porous and will absorb a lot of materials. this might be worth calling in a professional stone restorer.

Thanks! Yes, it is paint on the sides. I'm not sure what the stone is. I would like to clean up the front without the paint and try to get rid of at least the paint that shows on the side.

so, the paint is on the sides that we can't see? lol

try the heat gun.

any type of solvent is going to get absorbed by the stone.

if the heat gun doesn't work (you can rent one at Home depot or something) then call in a stone refinisher

looks like limestone

I am not sure that is paint and BTW your pic of the side did not post . IMO you need someone to tell you what the stone is for sure

It's going to be next to impossible to remove the paint. A heat gun, as others have suggested, might work. Chemical strippers might discolor the stone - so I would avoid those. If you try to brush it off I would only use a soft bristle scrubbing brush. I'm thinking that you will need lots of patience and elbow grease. Good luck!

We have two of these in one of our buildings. Ours, and I suspect yours, are cast stone (judging by the little bubbles around the edges). Ours mainly had paint at the edge of the wall, luckily ours was smooth there so 50% could be removed with a very sharp razor blade. The rest we removed with regular paint stripper (I think we used citristrip). We then recaulked the seams at the wall with color matched sanded grout caulk.

thanks! I will search for a stone restoration company in kansas city. Here is the side view.
