How to Clean Paint Off of the Side of a Brick House

Brick is porous, so when a substance gets on the surface, it quickly soaks in. If you find paint stains on the side of your brick house, soap and water likely aren’t enough to get them off. Removing paint from brick requires more aggressive cleaning products. Clean the paint off properly to preserve the integrity of the brick during the process.
