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.

While the benefits of high pressure water jets are numerous, it is essential for users to be aware of the potential risks. Improper technique can lead to damage to the vehicle's paint or sensitive components. Therefore, car wash operators must be trained to handle equipment properly and ensure users are informed about best practices.
