Power washing, also known as pressure washing, is an efficient and effective method for cleaning surfaces by using high-pressure water jets. It’s commonly employed for residential, commercial, and industrial cleaning tasks to remove dirt, mold, mildew, grime, and other stubborn stains from various surfaces.
This guide explores the key aspects of power washing, its benefits, techniques, and safety precautions.

What Is Power Washing?

Power washing uses a motorized pump to pressurize water and expel it through a nozzle at high velocity. The pressure effectively breaks down dirt and contaminants from surfaces. Power washing often includes the use of heated water, which is especially effective for removing grease and tough stains, whereas pressure washing typically uses cold water.
