The answer to 'pressure washer cleaning frequency' is that most experts recommend using a pressure washer to clean outdoor surfaces like driveways, patios, and siding every 6 to 12 months. This helps remove built-up dirt, grime, and mildew that can accumulate over time. Proper pressure washer use and maintenance is important to avoid damage to surfaces.
The ideal frequency will depend on factors like the climate, amount of foot traffic, and how quickly your outdoor surfaces get dirty. In general, it's a good idea to pressure wash at least once a year, and more often in dirtier or high-traffic areas.
