Best Car Pressure Washer Overview

It’s important to note that you aren’t looking for the most powerful machine when looking for a car pressure washer. Too much pressure has the potential to cause damage to the paintwork, rubber or other components of the car. Instead, you should look at car pressure washers that produce between 100 to 140 bar and provide a range of additional features.

Below is a list of the best car pressure washers that are safe to use for valeting and are packed with intuitive features.

Conclusion

Investing into a pressure washer for car valeting allows you to be more thorough with your car cleaning. It also gives you the opportunity to use some of the best rated snow foams, which covers your car in foam and acts as a pre-wash.

To avoid disappointment, we advise that you purchase from reputable brands in the UK that provide warranties. In terms of the power output, you will want to avoid excessively powerful machines unless they provide multiple power modes. As a general rule, we recommend car pressure washers that provide between 100 to 140 bar of pressure.

Using a pressure washer to wash your car is slightly more time consuming to setup but it makes the cleaning process much easier.

To begin, you’ll want to setup the pressure washer by putting it near the car, attaching a water supply and powering it up with an extension lead. You then have the choice of using a snow foam attachment and covering the car in snow foam as a pre-wash.

Regardless to whether you use snow foam or not, you can begin to use the pressure washer by rinsing the car down from top to bottom.

Afterwards, begin to wash your car as normal or insert a detergent into the machine to use instead of a standard car shampoo. Once you’ve covered the car in shampoo or detergent, put the pressure washer on a rinse setting and clear the car.

Using a pressure washer is really that easy and it gives you far more cleaning power for a deeper clean.

When it comes to cleaning cars, you don’t want to use a pressure washer that’s too powerful because you run the risk of damaging the clear coat or paint. Therefore, as a general rule, it’s recommended that you use a pressure washer that’s rated to a maximum of 2,000 PSI. Alternatively, if your machine is more powerful, you’ll want to set it to a “car” safe mode upon the trigger, which can be found on most Karcher pressure washers.

The average pressure washer for cars doesn’t use as much water as you would think and it actually uses less water than a standard hose pipe. This is because they have clever features such as automatic shut off valves that prevent the continuous flow of water as you are washing your car.

In terms of how much water pressure washers use, you’ll want to pay attention to the GPM (gallons per minute) rating of the machine. Most standard car pressure washers have a GPM rating of 2 to 3 GPM and on average, a pressure washer may run for at least 20 minutes per wash. Therefore, based upon these assumptions, a pressure washer can use up to 40 to 60 gallons of water per wash.
