How to Remove Paint From Limestone

Limestone is a natural stone that is common in building materials. As such, you can find limestone in your kitchen or bathroom counters. Monuments and buildings are made of limestone also. Removing paint from limestone can be difficult because limestone is a relatively porous surface that will absorb chemicals easily. Some chemicals, such as acidic cleaners, can etch limestone and permanently damage it.

Add 1 tsp liquid dish soap to 2 cups warm water. Do not use liquid dish soap that contains bleach.

Mix until suds develop in the water.

Dip a cloth into the soapy solution and dab it on the limestone. This will remove some or all of the paint if the paint is water-based. If the paint is oil-based, it may only remove some of it.

Dip a toothbrush into the solution and gently scrub the paint stain away. Do not use too much pressure as this might scratch the limestone.

Scrape off the paint with the edge of a plastic paint scraper. Do not use metal, as it will scratch the limestone easier.

Apply a small amount of paint thinner to a clean cloth.

Dab the paint thinner gently onto the paint stain until you remove the rest of the paint. Apply more paint thinner as needed but try not to get the paint thinner on the limestone surface.

Rinse the area with clear water and dry it completely with a clean cloth.
