Power washing is a cleaning method that uses high-pressure water spray to remove dirt, grime, mold, and other debris from surfaces. It is commonly used on driveways, sidewalks, decks, and the exterior of buildings. The powerful jets of water can effectively clean surfaces without the need for harsh chemicals, making it an eco-friendly option. This technique is often performed with a power washer, a specialized machine that can be adjusted for different pressure levels depending on the surface being cleaned. Regular power washing can help maintain the appearance and longevity of outdoor surfaces, preventing damage from accumulated dirt and organic growth.
