What Are Essential Pressure Washing Terms?


PSI: Measuring Pressure Intensity

PSI stands for Pounds per Square Inch, indicating the pressure force of water. It’s essential for breaking down dirt and grime on various surfaces. High PSI is useful for tough stains on hard surfaces, while lower PSI suits delicate materials. Correctly choosing PSI levels ensures efficient cleaning without damaging surfaces.
