wash and wax for pressure washer
Most commercial car wash machines typically operate at pressures ranging from 1,200 to 3,000 PSI (pounds per square inch). A pressure of 1,200 PSI is adequate for gentle cleaning and is often used for delicate surfaces or vehicles that only require light washing. In contrast, pressures exceeding 2,500 PSI are suitable for heavy-duty cleaning, making them ideal for trucks, SUVs, or vehicles that frequently traverse muddy terrains.

A gas pressure washer operates by utilizing a gasoline engine to power a high-pressure water pump. This combination produces a much higher flow and pressure than electric models, making it particularly suitable for automotive detailing. With pressure ratings often exceeding 3000 PSI (pounds per square inch), these machines can easily blast away dirt, grime, and stubborn stains from various surfaces of your car.
