Do and don’ts for cleaning your favorite car with a pressure washer.

Car wash Do or Don't

You should do


It’s excellent to avoid using a pressure cleaner machine on any parts of your car with harmed paintwork. The force of the pressure washer can exasperate and worsen these faults, creating an even more significant problem to solve with your shining compound and a dual-action polisher. It would be best to hand wash these areas with a plush, microfiber wash mitt and a light intentness of M.A.X. Power Detergent to save your vehicle from further damage.


Of course, several surfaces of your car can resist more pressure than others, so it’s essential to make sure you switch to the proper nozzle for the correct surfaces of your vehicle. For your paintwork and glass outside, we suggest a 40-degree nozzle. For your wheels and wheel arches, we also recommend a 25-degree nozzle to wash away all that brake dust and any studded soils stuck to your rims and sidewalls.

However, if your power washer unit does not come with these nozzle sizes, survey your builder to see if it’s secure to use aftermarket nozzles with your pressure cleaner.

Point the nozzle at the location for the primary burst of water when you start. Power washes the car on concrete rather than grit to get off the possibility of stones hitting the paintwork.

When it comes to suitable pressure washers, closeness is just as significant as pressure. It would be best if you never gripped your machine nozzle close to the paint surface. While this may seem like a massive way to take out incredibly stubborn soils, you can just as easily scratch or harm the clear coat.

A helpful rule of thumb is the “six-twelve (6-12)” rule: every time, keep the nozzle of your power cleaner at least 6 inches away from the paint and 12 inches away from trim. It generates a stream of water, powerful enough to tackle hard stains and grime without damaging the surface of your car.


The nozzle of an electric pressure washer is often changeable, permitting you to switch to a greater or smaller spray model, depending on the surface you’re trying to wash. The smaller the nozzle is, the more precise and very mighty the stream of water. Surfaces like parking lots and concrete footpaths need a 10 to 15-degree nozzle for heavy-duty washing.

Moreover, do not use a nozzle with less than a 25-degree spray pattern to pressure wash your car. If you are afraid of which size nozzles came with your car wash machine, check the manual properly or ask the manufacturer.

Remember, you should also never set your pressure washer above 2500 psi when washing the car. 1800 psi is verily all you need to get a good deep wash; any pressure higher than that won’t make a remarkable achievement difference. Moreover, you can use the multiway unloader valve to set the pressure washer to more tremendous or lower pressure.

Do not spray too close to the paintwork or straight at panel gaps for too long. It will cause marks, which can be a pain to get rid of it. Rater, use sturdy spray-on zones where paint is chipped or on old tires. Use a rotary (or twister) nozzle attachment and spray the engine bay.

The pressure washers work by taking the quality flow of a call equal to 10 GPM and placing it under pressure which diminishes the flow. Therefore, you cannot possibly use more than your outlet puts out, 10 GPM or 100 gallons of water to wash a can within 10 minutes.

The rate of water used in a car wash relies on the process utilized: Friction in-bay automatic ways use probably 35 gallons per vehicle. In-bay automatics that employ the high-pressure touchless system use 70 gallons per vehicle.

Other hands, Pressure washer machines use between 2 and 10 GPM of water. The water expense of light-duty pressure cleaners is 180 GPM, on average. The quantity is similar to the amount utilized while washing the dishes in a sink, which varies from 2 GPM to 5 GPM. Heavy-duty washers take up to Ten GPM, which sums up 600 gallons per hour.
