The Ideal PSI for Pressure Washing Your Car
Key Takeaways
- The ideal PSI range for washing a car is 1,200 to 1,900 PSI, with 1,200-1,500 safe for routine washes.
- Flow rate of 1.5-2.5 GPM helps loosen dirt without needing extreme pressure.
- Use a 25- to 40-degree nozzle and avoid narrow 0- to 15-degree nozzles to prevent damage.
- Keep the nozzle 12-18 inches from the surface and use steady, sweeping motions.
