How We Rated The Car Pressure Washers

After years of cleaning cars with a pressure washer, we have tried and tested a range of different machines. As well as our experience of pressure washing cars, we also based the recommendations within this article upon multiple factors. The factors that we considered included their electric motor, performance, power cord and hose length, weight, warranty and value for money.

Car Pressure Washer Buying Guide

If you want to water your flowers, a normal hose is fine but there are times when a garden hose with a nozzle/sprayer isn’t enough. When it comes to serious car cleaning, you will need a car pressure washer.

Tough dirt and grime can be impossible to remove using a standard hose. However, by using a pressure washer, you can safely remove them with ease. There are a range of pressure washers available and it’s important that you choose one that best suits your requirements. To help you make an informed buying decision, we’ve produced the below guide regarding car pressure washers.

Pressure Washers For Cars

There are a number of pressure washers available but it’s essential that you get one just for auto detailing. This is because some pressure washers are designed for different applications such as remove staining from fences, clearing concrete and much more. An electric pressure washer for cars will have a PSI rating that’s safe for use on cars and won’t damage the paintwork.

A PSI rating of around 2,000 is ideal for cleaning cars, trucks, boats and much more. It can also be used for cleaning patios, fences and other applications but if this is the sole purpose, the best option is to go for a higher PSI pressure washer.

How Much Water Does It Use?

If you care about the environment or are on a water meter, the amount of water it uses is very important. It’s estimated that the average car pressure washer uses approximately 7 to 9 gallons of water per minute.

When reading the specification of a pressure washer, look for the GPM (Gallons Per Minute) rating because this gives you an indication of how much water it uses.

A higher GPM means more water comes out of the nozzle, which provides the car with a better rinse. If both ratings are high, then the washing will be much quicker but the efficiency of water used may not be as good.

Foam Cannons

Attaching a foam cannon to a pressure washer allows you to spray thick foam all over your car. The purpose of this is to act as a pre-cleaning stage but it also provides the perfect photo opportunity whilst the foam is getting to work on the car.

Foam cannons usually work from 55 to 90 PSI and produce a large amount of foam with a flow rate of up to 5.5 GPM. Most simply click straight onto the pressure washer whereas others you may need a certain adapter.

If you haven’t got one yet, we wrote an article on the best rated foam cannons that features a list of models suitable for all budgets. They are one of the best attachments you can get for you pressure washer and can help reduce scratches and swirls appearing on your paintwork. Below is an example of what the foam looks like on your car once sprayed from a pressure washer.

Gas vs Electric Car Pressure Washer

You will notice that all of our recommended pressure washers for cars are all electric. This is because most are rated to a PSI of up to 2,000, which is ideal for washing cars.

Gas powered pressure washers deliver a much higher PSI rating with even the low powered versions producing well over 2,000 PSI. There are even some capable of producing over 7,000 PSI, which isn’t safe for car detailing.

Electric pressure washers for cars are far more practical too because it takes one button to turn it on or off. The gas alternative requires you to tug on a rope to get it to start and you also need to remember to fill it up with gas. Other inconveniences with gas machines is that it needs servicing, it’s much heavier and it also uses far more water too.

To conclude, the best pressure washer for cars is an electric powered model because there isn’t a real need for the additional power. Most people want to simply flick the switch and turn on a pressure washer and not worry about fuel or servicing.

Pressure Washer Nozzles

The nozzle is one of the most important components and without one, the pressure washer will be useless. You will want to look out for a nozzle that’s adaptable and allows you to change the width of the spray.

You won’t always want a narrow spray of water as this will be too powerful and could be a major risk to the paintwork. Adjusting the spray to a wider setting for certain areas of the car helps avoid any damage.

How To Use A Car Pressure Washer

Everyone has their own way of washing cars but when using a pressure washer, it’s much more fun and easier. Below is a guide on how to use a pressure washer for car detailing:

  1. Pre-clean – Before you use any wash mitt on your car paintwork, you should always rinse the car starting from the top and moving your way down. Be sure to take extra care over the lights and any body trim.
  2. Apply Detergent – Fill your car pressure washer with a detergent and then spray it onto the car using the widest setting for full coverage. Do not remove the detergent straight away but instead wait at least 5 minutes for it to soak up the dirt.
  3. Remove Dirt – Using a wash mitt, simply wipe away all the detergent from the car and then rinse it away.

Once the pre-clean stage above is complete, you can move onto washing the car with your car wash soap and spray it using the pressure washer.

Motors and Pumps

The electric motor of a pressure washer and the power they output is determined by the wattage and amperage. The three types of electric motors are universal, induction and water cooled. These three types are in order of cost, performance and noise levels.

If you are stuck between two car pressure washers that are priced the same, check to see which electric motor it uses. If one is water cooled over an induction motor, you will have a clear answer to which is the best pressure washer for the money.

Just as important as the electric motor is of course the pump because it must be able to handle the power of the machine. There are three types of pumps, which include wobble, axial and triplex. These are ordered based upon their lifespan and ability to withstand large amounts of power.

Other Important Features

There is so much to talk about with regards to pressure washers, so we will keep it short.

In terms of usability, electric machines require a power cord, which needs to be long enough to reach an AC outlet and not too close to any water. It’s not only length you need to look out for because the hose length is also something that can be either too short or too long. If it’s too long, it can get in the way but too short and you will find yourself knocking over the pressure washer.

Detergent intake may also be an issue for some auto detailers as some are a suction tube or a plug and clean system. There are also many different detergent soaps you can use too but this is for another article.

A pressure washer for cars is a tool for detailers, just like the cement mixer is to a builder. Investing into one that comes with a long warranty, variable settings and plenty of features is a worthwhile investment.

As most people will own a pressure washer for many years, it’s worth paying extra for one that offers more functionality. Sun Joe and Karcher are the best branded machines but they usually come at a premium price.
