pressure washer psi for car Page 4

For washing a car without sandblasting the paint, aim for 1,200–1,900 PSI (≈80–130 bar) with a 25°–40° fan nozzle. Keep the tip about 30–50 cm from the surface and sweep side-to-side like you’re painting a fence you don’t own. Flow of around 5–8 L/min is plenty; you’re rinsing, not stripping barnacles. Avoid close-up blasting of tyres, rubber seals, badges, and radiator fins, unless you enjoy leaks and rattles. Pre-soak with a pH-balanced snow foam and rinse from top to bottom—because gravity works even on Sundays. Consult official documentation for exact figures.
