Remove debris from dirty painted walls with this quick how-to guide – and make sure your space is showing the beautiful color you want it to.

1. On exterior surfaces, dirty paint is often caused by soil that splashes onto your siding, by air pollution or by car exhaust.
2. For interior surfaces, airborne dust and household dirt are common causes.

Wash the surface. If it comes clean, repainting may not be necessary.

On interior surfaces, remove stains, dirt and marks with a soft cloth or sponge and with water or a general-purpose household cleaner. For penetrating stains and marks, try a) a mild detergent first, or b) use an abrasive cleaner with water. Always test in a smaller area before applying to the entire surface.

For exterior surfaces, remove dirt a) with a scrub brush and detergent solution or b) by pressure washing and a thorough rinsing. While dirt accumulation cannot be eliminated entirely, satin, gloss and high-gloss paints are more resistant to picking up dirt than flat paints due to their smoother finish.
