Pressure washing is the process of using high-pressure water spray to remove dirt, grime, mold, mildew, and other contaminants from surfaces such as driveways, sidewalks, decks, and building exteriors. It is an effective way to maintain the appearance and integrity of outdoor spaces, preventing damage caused by accumulated debris and growth.

The process involves using a pressure washer, a machine that sprays water at high velocity, often combined with cleaning solutions for tough stains. Pressure washing should be performed as needed, typically once or twice a year, depending on environmental factors and the type of surface being cleaned.
