How to clean a car with a pressure washer? - The basics
Considerations when buying a pressure washer to clean your car
The most important things to factor in are water pressure (PSI the higher the more powerful a blast of spray from it), water flow (measured in litres per hour) and the pressure washer power in watts (the higher the wattage the more powerful the washer).
Try to find a pressure washer with all three combinations you need to clean your car.
Tips for cleaning your car with a pressure washer?
What pressure washer nozzle should you use to clean a car
White head (40 degrees) nozzles are the safest for cleaning your car plus you can reach and rinse a greater area plus it wont damage your paint. I would stay away from green, red and yellow coloured nozzles for cleaning your car.
What PSI is best when cleaning your car with a pressure washer?
Start with a low pressure then slowly turn it up. I recommend choosing a pressure washer with the setting of 1200 to 1900 PSI. It is safe to use on cars, therefore you won’t have to worry about damaging the paint. Always try and go for a pressure washer with the setting of 1.4 to 1.6 GPM.
Things to be careful of when cleaning your car with a pressure washer
Is it safe to use a pressure washer to clean your car?
As long as you choose the pressure washer with the setting of 600 to 1900 PSI and you choose the right nozzle (a white one) It is definitely safe to use a pressure washer on your car and you won’t need to worry about damaging your paint work or your car.
Can pressure washers damaged the paint work on your car?
As long as you don’t choose a pressure washer over 2000 PSI and don’t hold the nozzle too close to the car you will be fine. Always make sure to choose a pressure washer between 600 and 1200 PSI and use the white nozzle.
If you were to use a massively high powered machine and you held it too close to the car, it would definitely take the paint work off your car.
Try the pressure washer on an inconspicuous part fo the paintwork first to check all is ok.
