How to Get Red Mud Off Aluminum Siding

Aluminum siding is a low-maintenance material for the exterior of your home. If you care for it properly, your aluminum siding can last for years. Red mud in the soil is notorious for creating stains on clothing and can make a mess on your siding, too. If a hard rain has caused red mud to splatter on your aluminum siding, it's best to clean it before the sun has a chance to bake the mud. You can remove the red mud stains with effective household supplies and proper cleaning techniques.
