When to wash a car?

Washing the car with a pressure washer: Tips
Do not expose your car to large temperature differences when washing it. Therefore, do not wash your car with a pressure washer in winter when the temperature is below -10 degrees Celsius. The warm water can otherwise cause fine cracks in the cold paintwork. When cleaning in summer, wait for the morning or evening hours and do not stress the heated paintwork with cool water. If the outside temperature is very high or very low, we also advise against hand washing or a trip to the car wash.
When washing your car, use the high-pressure washer at a shallow angle, with little pressure and at a sufficient distance (at least 25 centimetres) from the vehicle. If the pressure is not enough to loosen the dirt, you can slowly increase it. However, too much pressure (more than 200 bar) can damage the paint.
Can I use a pressure washer to wash the car?
Washing the car with a pressure washer on your own property or on the open road is not allowed everywhere. The water jet can loosen oil from the car, causing the oily water to get into the ground, water bodies or sewage system. Even the oil-free wastewater must not be allowed to run off into the sewage system or an open body of water. Both would pollute and endanger the environment.
For this reason, car washing is often only allowed in places with an oil separator in the water drain, such as car wash facilities. To protect the environment, we recommend that you only clean your car in car washes that are approved for this purpose. In any case, find out about the applicable rules in your municipality before you start washing your car.
Washing a car: Legal
Car washing on private property is only permitted under strict legal conditions. Therefore, please observe the local regulations regarding the permissibility of car washing. To be on the safe side, find out about the relevant regulations from your local municipality.
How to wash a car with a pressure washer?

You can find details in the operating instructions for your product. Familiarise yourself thoroughly with your machine before using it for the first time and ensure that your machine is in perfect condition before each use.

Remove leaves and branches
First free the car by hand from loose dirt such as leaves or twigs. This prevents the wood from scratching the paintwork when you point the pressure washer at the car.
Rinse off coarse dirt with pressure washer
Now start washing the car with the pressure washer. Use the flat spray nozzle and start with the lowest pressure. Always keep a minimum distance of 30 centimetres from the car to avoid damaging the paintwork and delicate rubber parts. Aim the water jet at your vehicle at a shallow angle to rinse away coarse dirt. You can also treat rims and tyres carefully with the high-pressure cleaner. Rubber car parts should not be subjected to a direct hard water jet.
Apply vehicle shampoo and rim cleaner
Apply rim cleaner to heavily soiled rims. Fill vehicle shampoo into the spray set according to the operating instructions and attach the spray set to the high-pressure cleaner. Now spread the cleaning agent over the car with the high-pressure cleaner. Make sure that you only treat the metal parts with the vehicle shampoo, as the wax contained is not suitable for glass and plastic surfaces. Let the cleaning agent work for a few minutes.
Remove dirt with a brush or sponge
Attach the washing brush to the pressure washer and wash the car with it. Alternatively, you can use a soft sponge. Now clean the rims from the dirt that has soaked in in the meantime.
Rinse and dry off
Rinse your car with the pressure washer until no residue of dirt or detergent remains. Then dry the car with a soft cloth or chamois leather.
