The answer to 'pressure washer mold' is that pressure washers can be an effective tool for removing mold, but they must be used properly to avoid making the problem worse. Mold can grow on a variety of surfaces, including concrete, wood, and siding, and a pressure washer can help blast away the mold and its roots. However, using too much pressure or the wrong technique can actually drive the mold further into porous materials and spread the spores.
The key is to use the lowest effective pressure setting and keep the wand at least 6 inches from the surface. Start with a mild detergent or bleach solution to kill the mold, then rinse thoroughly. For stubborn mold growth or large affected areas, it's best to call in a professional mold remediation service to ensure the problem is properly addressed.
