How to wash your car with the pressure washer

1. Connect the pressure washer to the power source and to the water supply

Get your pressure washer ready and plug it into the power source as well as to the water supply. Once this is in position, you can then switch on your pressure washer from the power source. Before you start using it, ensure that there is a steady flow of water.

2. Rinse the car with clean water

This process aims at removing any loose dirt and dust from your car’s body. Use a high-pressure setting to achieve this objective. Remember to keep some distance of about 20cm between the car and nozzle to prevent damages on your car as a result of the high pressure.

Tip: Rinse in sections rather than trying to spray water all over the car in one go. This promotes consistency. NEVER spray the engine bay and DO NOT concentrate on one area for too long.

3. Apply some detergent

Place the detergent solution in your pressure washer’s chamber and change the nozzle into a low-pressure setting. Spread your detergent putting in mind that you should not allow it to dry. Systematically apply the detergent from the top of the car as you work your way towards the bottom.

The tougher sections such as the wheels, the truck bed, and rocker panels can be cleaned under high pressure. This will get rid of any cake mud, grime, and/or dirt.

Tip: Dilute the detergent to the required levels.

4. Rinse off the detergent

You may choose to either remove the detergent chamber or switch the washer to the lowest setting before starting to rinse the car. Thoroughly rinse your car until all the detergent is eliminated.

Tip: If you have spotting on your car, it is advisable that you consider using non-spotting rinse solutions. This should however be applied to the affected areas only.

5. Dry your car

Using a chamois leather cloth or shammy, dry your car and this will leave a lustrous shine on its body.

The above process will ensure you thoroughly clean your car while at the same time preventing any chances of damaging your car’s paint job as long as you use the process as required. It is fast, easy, and does not require the use of so much energy. It is therefore, convenient and fast.
