So, at first, follow the instructions carefully before purchase and use a pressure washer and ensure that the machine is ideal for washing your car and for your washer. You have to gather some information about PSI and Cleaning units which I am going to tell you below with some easy equations.

Which type of pressure washer you have to choose

Firstly, you have to decide to purchase a pressure washer that you want to use which is very effective for you and your car. Usually, two types of pressure washers are available in the market. One is an electric pressure washer and another is a gas pressure washer. A gas pressure washer has a very strong cleaning capacity and it is to operate heavy-duty works like trucks, roads, and industrial buildings. On the other hand, to avoid damage to your vehicle, you are suggested to use an electric pressure washer that has an appropriate PSI.

An electric pressure washer has enough power to perform this job properly. You have to choose an electric pressure washer which has a PSI range from 1200 to 1900 and has 1900 to 2800 cleaning units.

Measurement of cleaning units

When you use a pressure washer to wash your car appropriately, it is important to gain some knowledge about the cleaning units which can be determined by PSI (Power measured by pounds per square inch) and GPM (water flow measured by gallons per minute). Higher PSI can increase the force of the water that will release from the tip of the washer and higher GPM can increase the water flow that releases from it. Cleaning units can be calculated from the combination of force and amount of water flow that is released from the washer.

So, cleaning units = PSI×GPM.

A range from 1900 to 2800 cleaning units is recommended to use as it is very effective for you and your car. An average garden hose has 40 PSI and 7 GPM, so the cleaning unit is 280. And a pressure washer for a car has 1500 PSI and 1.5 GPM, so the cleaning unit is 2250. Experts recommended using a pressure washer which has a range of 1.4 to 1.6 GPM.

Select the right nozzle

After choosing an appropriate pressure washer you have to choose a perfect size nozzle from different types of nozzles. It is very important to choose a perfect size nozzle so that you can clean your car effectively without damaging your paintwork. You have to keep in mind two things for choosing a pressure washer. One is pressure level and another is nozzle size. Narrow nozzle type covers a small area whither wider nozzle type covers a large area but it has less pressure.

Different types of nozzles are available and you must choose the right angle or degree out of them for the convenience of your work and complete the work very easily.

  • 0-degree which is marked by red color. This type of nozzle is mainly used in a high-quality job like removal of stains from cement, bricks, or solid metals as we know it has very high pressure. It is not suitable for car washing.
  • 15-degree which is marked by yellow. This nozzle used to remove dirt from the footpath.
  • 25-degree which is marked by green. It is mainly used to clean wheels and trucks and rinse the mud off the surface of the car.
  • 40-degree which is marked by white. It is mainly used to clean a large area very fast. It is suitable for washing a car.

Here, you are suggested to use a 25-degree (green) or 40-degree (white) nozzle. You must avoid lower degree nozzles ( 0 or 15-degree nozzle) where there is a risk of damage to your paint.

Before it, you have to check the pressure of water by spraying some water approximately 4-5cm wide on the ground to make sure that it is not so strong. You have to stay 4-5 feet away from the car and after testing the pressure washer get closer to the wheels to remove tough bugs and mud.

You must ensure that all the windows are rolled up and the doors and trunks are closed so that the water can not come into the interior of your car. Be careful when you work on delicate items like side-view mirrors, headlights, brake lights, etc. Move a little further back when you work on these parts. 

Experts recommended spraying water at a downward angle. A straight spray of water causes any kind of potential paint damage.

Step-3: Select and use the proper detergent

You must select a proper detergent from special compartments of it. You must make sure that the detergent that you purchase must be designed for your pressure washer and suited for your car. These detergents remain in concentration and they need to dilute with a proper amount of water before spray it in your car. In below, here are 3 procedures for the application of specific detergents by a pressure washer.

  • Dilute it into a bucket with a proper amount of water: Don’t forget to hear the proper concentration ratio of detergent and water from the manufacturer or retailers. You must read the manufacturer instructions from the label of detergent packs.
  • Fill the detergent tank with diluted detergent: You must set the nozzle of your pressure washer wider and less powerful rather than water onto the car. For this, you need to fix your pressure washer setting. If you have not found any detergent tank, apply the detergent with a cloth by hand but be careful when you do this, don’t scrub your vehicle hard just simply coat the car.
  • Spray from the top: Apply detergent from the top of your car. You can spray one side of your car at a time and another side next, or you can wash your car entirely at once. You must avoid, not to spray inside the engine. Don’t forget to spray soap in the wheels and under the car by making the nozzle upward angle that will be convenient for you. Let the detergent for five minutes in a car. Of course, don’t let it dry and let it works its magic.

Step-4: Loosen the stubborn dirt and mud

For this, you must use a car brush that is suitable for this work and it must be attachable. You can also use it to remove all dirt and mud from your car wheels and under the car. Be careful when you use it on paint, glass, signal lights.

Step-5: Time to rinse the detergent

After a few minutes, you have to remove the detergent tank and rinse the whole car with water through your pressure washer. Select a 40-degree white nozzle to rinse your car. Experts recommended holding the pressure washer 45-degree angle and rinse from top to bottom on the downward movement. You can also use a towel or other soft cloth to dry the car after rinsing by water and stay it to fully dry.
