Yes, this is basically what you are doing at a car wash. A pressure washer is just a motor and a pump that shoots water at high speeds, and high pressures. A pressure washer is a great way to wash your car, but there are a few things that you should keep in mind:

  • Make sure that you do not use too much pressure. I would not recommend using more than 1500 PSI to wash your car.1
  • The more flow you can get, the better, look for something around 3 or 4 GPM.2
  • Get a water filter. You do not want small sediment in your water damage the paint job on your car (or your pressure washer).
  • Do not leave the trigger in the "closed" position for more than 15 or 20 seconds. This can cause the pressure washer to get hot due to the friction produced when the same water is recirculated multiple times. If you are going to stop washing to apply soap, then just turn off the pressure washer.

*Tip- To save time, you can use a chemical injector to add the soap to the stream of water from the pressure washer. This is now pretty much the same setup as in a car wash.

Exactly what do you wash with a pressure washer?

If you use a pressure washer like the 'Karcher K2' which has a 110bar pressure you can safely use it on your car, but I wouldn't use it at close range. There are plenty of other items that can be cleaned this way, i.e; patio, decking, bicycles, garden furniture and windows.
