Pressure washing is a highly effective method for cleaning surfaces by using a powerful stream of water at high pressure, typically measured in pounds per square inch (PSI). This high-pressure water is capable of removing dirt, grime, mold, mildew, algae, fungus, moss, and other debris from various surfaces such as sidewalks, driveways, decks, siding, and vehicles. The force of the water is what primarily dislodges and washes away the contaminants, leaving the surface clean and refreshed. Additionally, pressure washing can often be enhanced with the use of cleaning solutions or detergents tailored to specific cleaning needs.
