How Much Pressure Do Car Washes Have

Car washes typically blast out their liquid at 1,000 to 1,200 PSI, although pressures can go up to 2,200 in some situations. For this reason, along with the squirts of hot wax and slaps from towels, we do not recommend going through a car wash on foot.

Is 2000 psi too much to wash a car?

Anything less than 2000 PSI should be fine for pressure washing your car to get it clean. Most cheap small electric pressure washers likely won’t come close to this amount of pressure but should be more than adequate for washing a car.

How much PSI is a commercial car wash?

Most commercial car washes run at 750 to 1,000 psi — and that’s water against metal. So how much more could you need to clean a wood deck? Think less, not more, or the high-powered jet will blast away soft surface wood leaving an uncomfortable, almost corrugated surface.
