Pressure Washers For Car Cleaning: What You Need To Know.

There are several pressure washers on the market and it’s important to know what you’re getting so that you can make the most of your new washer. Similar to other cleaning appliances, pressure washers are not made equal. Some units are designed for specific tasks such as cleaning concrete or removing stains from fencing and are often powered by gas.

Electric pressure washers are suitable for car cleaning because of the safe PSI level, therefore, the water pressure will not strip the paint work from your car.

A PSI of 2,000 or less is safe for cleaning cars, vans, trucks and other types of vehicles. At this level of water pressure, you can also clean the outdoor decking, the patio, pavement, windows and other areas. If you are not intending to use your pressure washer for car cleaning then you can choose a unit with a stronger PSI water pressure.


Does a Pressure Washer Use a Lot of Water?

The capacity of water used by pressure washers varies between each model and if your water runs on a meter or if you want to be kinder to the environment then you should carefully consider the amount of water the machine needs. Typically, a car pressure washer will spray between 6.5 to 9 gallons of water every minute.

Before deciding which pressure washer to buy, ensure that you check the gallons per minute or GPM rating in the product specifications. This measurement will demystify the guesswork around water usage. Naturally, a higher number equates to a higher rate of water from the nozzle, therefore, providing a thorough rinse. Cleaning is much quicker with a high GPM rating but water efficiency suffers as a result.


Pressure Washer Foam Cannons

For the best possible car cleaning results, you should consider a foam cannon which effectively suds up your ride prior to rinsing. The foam produced by the cannon cuts through difficult dirt such as mud and dead bugs, the thick detergent is quick to act and even quicker to apply to your car’s bodywork.

A cannon will start to produce foam when the water pressure reaches between 55 to 90 PSI. It delivers plenty of foam at a rate of approximately 5 gallons per minute. The best thing about a foam cannon is that most of them can be simply attached straight to the pressure washer hose as you would with a nozzle, other types of cannons might require a special adapter to connect.

It goes without saying that a foam cannon is a vital accessory for car cleaning and it improves the end result considerably. The image below gives you an idea of what your car will look like when the foam is applied using a pressure washer cannon.


What is the difference between a Gas & Electric Car Pressure Washer?

In this post, I’ve specifically focused on electric pressure washers for car cleaning. Why is that? An electric pressure washer uses a high amp electric motor to provide adequate water pressure of 2000 PSI which is perfect for car cleaning.

Gas driven pressure washers are a lot more powerful and produce a higher PSI. At the lower end, these appliances deliver more than 2000 PSI. The best gas pressure washers deliver a staggering 7000 PSI and are normally used commercially. Most of us wouldn’t need such a powerful machine for domestic use and definitely not for car cleaning.

The higher PSI on gas-powered pressure washers means that they use up more water than electric pressure washers.


Electric pressure washers are far more convenient to use and simply require turning on a switch or pressing a button to bring it to life. With a gas version, you’ll need to tug a rope to get the motor going and don’t forget that you’ll need to purchase the correct fuel compatible with your machine. A gas-powered pressure washer requires more maintenance, it will need regular servicing and for the filter to be replaced to run optimally.

Electric pressure washers do not weigh as much gas versions, however, you need to find a close-by power source to plug them in, unlike a gas appliance which is more mobile.

Overall, the best pressure washer for car cleaning is an electric version because you don’t need the extra power provided by the gas model. In fact, the additional power could damage your car’s paintwork! Most of us want the convenience of turning a switch and getting on with the job rather than sourcing fuel before we can even get started.

What about Pressure Washer Nozzles?

The pressure washer nozzle is another vital accessory needed to operate the unit, without one, your pressure washer simply wouldn’t work. The best nozzle can be adapted to different cleaning scenarios and let you adjust the range of the spray.

A narrow spray of water is the most powerful but should be used with caution on paintwork, it’s best to use a narrow spray on areas such as the car tyre and rims where the most dirt can be found. Be sure to change the spray to a wider width for paintwork.

Using Your Car Pressure Washer Effectively

We all clean our car using different techniques, however, when we add a pressure washer to the mix, it is much easier and quicker compared to a bucket and soap. You should also follow the best practices described below to get the most out of your pressure washer cleaning session:

  • Pre-cleaning: It’s always a good idea to start by rinsing off your car from top to bottom before using any washing accessories i.e. sponges or mitts. Be extra careful when working around the lights.
  • Soap: Add soap to your car pressure washer and proceed with spraying it across the vehicle using the widest possible setting to ensure that you get a comprehensive application. Leave the soap to work into the dirt for about 5 minutes.
  • Washing away dirt: Use a sponge or mitt to wipe the soap off the bodywork, then proceed with spraying the vehicle with a higher pressure setting.

When the above stages are complete, you can begin washing the car with your chosen car shampoo and use the pressure washer to spray this on. The appliance would have already thoroughly removed stubborn dirt, therefore, you won’t have the trouble of getting rid of swirl marks later on using polish.


Pressure Washer Pumps & Motors

The power output of the motor on an electric pressure washer is measured by amps and watts. The most common types of electric motors are universal, induction and water cooled motors. I’ve listed them in order of price, audible levels and performance.

If you can’t decide which electric pressure washer to buy and they are around a similar cost, then you should check which motor they are equipped with. If for example there is an option for a water cooled motor or a universal motor then you should go for the lata.

The type of electric motor you choose is important, however, the pump is just as important as it determines how much power it can tolerate from the motor. You will find 3 types of pumps- wobble, axial and triplex. Again, these have been listed in order of longevity and their ability to tolerate big levels of power.


What else should I look for in a Pressure Washer?

It’s fair to say that electric pressure washers are a must-have outdoor cleaning accessory that help to get rid of exterior dirt quicker than any other method . Before deciding which model to buy be sure to check that the power cord is long enough to reach a power outlet with a safe distance between the water and electrics.

The length of the hose will also affect performance. You want one that strikes a good balance i.e. if it’s longer than normal then it could become an obstruction. If the hose is too short it could snag and constantly topple the machine.


The convenience of a pressure washer is only fully appreciated from the moment you start using it. It can be used for a variety of cleaning scenarios and the models come with a lengthy warranty, interchangeable accessories for various tasks and adjustable settings. A pressure washer is an appliance that you will use frequently, therefore, it’s worth spending a bit extra for a quality machine that will stand the test of time.


The best models are manufactured by brands such as Karcher (German engineering!) or Sun Joe. You might pay a bit more for these models but your investment will actually save you money in the long run- there is hardly any type of maintenance required and the rich set of features means that you can cover a variety of tasks with just this one machine.

Are you considering buying a pressure washer to wash your car and for outdoor cleaning or do you already own one? Please leave your comments in the section below. I’d love to hear from you.
