Vacuum the painted brick to remove built-up dust, dirt or debris using the vacuum's brush attachment.
Put on a pair of chemical-resistant gloves. Dampen a rag with paint stripper. Hold the dampened rug over the brick for a few minutes. The longer you hold the rag on the bricks, the more paint will come off.
Wipe away the paint stripper with a rag dampened with water.
Use a wire brush to scrape away a small amount of paint in other areas.
Mix 50 percent paint and 50 percent water in a mixing container. Stir with a stir stick until thoroughly combined. Chose a dark paint to simulate dirt and grime from years of use.
Dip a clean rag into the paint and rub the paint along the edges of some bricks. Wipe away the excess paint with a clean rag.
