Buyer’s Guide – What to Look for in a Car Pressure Washer
Not all pressure washers are suitable for cars. Here are the most important factors:

- GPM (Water Flow): Look for at least 1.2–1.6 GPM for effective rinsing and soap removal.
- Nozzle Selection: A 40° or 25° nozzle is safest for cars. Avoid 0° nozzles completely.
- Foam Cannon Compatibility: A foam cannon or soap tank is essential for swirl-free washing.

The 40° nozzle is safest for paint. Use 25° for wheels and undercarriage.
