Pressure washing cars are used quite a lot to wash cars at the private homes of most drivers.
The engine pressure washer can easily remove stubborn stains in seconds, which takes a lot of time with conventional cleaning tools.
However, whether pressure washing cars good or bad, or “Is it ok to pressure wash a car engine?” is still controversial. You and I will find out together through this article.
Pressure Washing Cars Good or Bad
Usually, for motorbikes, the high-pressure water car pressure washer must have a water pressure of 50 – 70 bar; for cars, the force required is 70 – 150 bar.
Choosing the proper pressure makes the job lighter with just a few simple steps, saving time, effort, and personnel costs.
However, if the water pressure washer is too high, it will easily cause problems such as car scratches, strong water spray on the internal engine can cause shorts, etc.
Therefore, a car pressure washer will have both good and bad sides.
Advantages
The advantages of pressure washing cars mostly come from specialized pressure washers.
A car engine washer with a serviceable lifespan can far outweigh the cost, and a multi-purpose washer saves much time doing other things.
Professional car washes rarely fail or need repair, have appropriate durability, and are worth the investment.
When washing a car with an electric pressure washer tool, it can clean all stains quickly thanks to excellent water pressure.
We only need a small amount of water with solid capacity, helping you save electricity and water.
Disadvantages
Improperly washing the car with a pressure-wash engine block can lead to vehicle damage and scratches.
For example, a driver applying too much pressure on the car’s body will directly damage the car’s interior.
Pressure washer damage car paint chips, even causing an electrical short when directly contacting the electrical circuit under the vehicle.
Overview of Pressure Washing Car Washers
Structure
Many different engine pressure washers are on the market, so these models have their structures and designs.
But in general, the type of pressure washer still has the same structural parts as electric motors, pump heads, and accompanying accessories such as a water spray gun, spray line, pressure washer nozzles, water supply lines, etc.
Operating Principle
Although there are many different product lines, industrial car washes all operate according to a common principle to achieve the best way to wash your car:
- When starting the machine, the machine’s motor will work, causing the water supply line to draw water from the supply source. The water supply head is designed with a filter to help remove dirt and debris in the water supply, helping to avoid engine clogging and affecting the capacity and life of the machine.
- The inlet water flows to the double-layer casing surrounding the motor to lower the temperature of the hot electric motor.
- Then energy is generated from the engine bay, and the piston at the pump head will start to reciprocate, helping to guide water to the intake valve into the piston chamber. Next, under the action of the piston, water will be pushed out of the piston chamber to the one-way valve to increase water pressure.
- After the pressure is increased at the one-way valve, the water flow will reach the pipe and be removed by the nozzle unit. The nozzle will continue improving the water pressure with the narrow cavity design.

How To Correctly Pressure Wash A Car
Carry Out Flushing of Contaminated Soil With Water.
Before using the cleaning pressure washer, flush the stubborn dirt with water first. This is the best way to start, especially with vehicles with dirt and grime.
In addition to removing stains, rinsing makes the detergent much easier to stick to the car and helps disperse the cleaner more effectively.
Rub Detergent by Hand.
Car washers should rub the soapy water (wash soap) with their hands while using gloves to remove stains that water cannot wash away.
While pressure cleaning is more effective, hands are better at eliminating crevice stains.
Use a Curved Nozzle
Using the head of the hose to flush the warm water directly will make the car prone to scratches. So use a curved nozzle that has an angle of about 25 degrees.
The water flow will be manageable enough to complete your desired cleaning job.
Clean the Undercarriage
The undercarriage is where dirt and sand cling the most. So please pay attention to the undercarriage and take the time to clean it.
To do this efficiently and quickly, look for a nozzle that has a 40-degree angle so you don’t have to bend over while flushing.
Notes When Using Pressure Washing Cars
To solve the anxiety of the question “Should you pressure wash your car?” you need to follow these notes correctly using a washer:
- Do not spray water hoses directly on people or pets because it will cause danger due to the intense water pressure of the foam cannon. Nozzle gas-powered pressure washers should not be used further than 5 Square Inches.
- It is necessary to select the appropriate spray for each washing position (safe distance), and the gun head should be kept away from the body when adjusting the water jet.
- Always ensure a clean and stable stream of water source, and add water in time when the water source is almost out to avoid machine fire.
- For the machine to work better, you need to place the water inlet position lower than the outlet.
- Avoid continuously squeezing/releasing the spray gun’s trigger during use because it may cause an engine fire.
FAQs
Is Washing a Car By Hand Better Than a Pressure Washer?
You should wash loose dirt on your vehicle surface with a gas-pressure washer rather than by hand or garden hose.
Because flying with a foam cannon will help save water and wash vehicles with water more by hand.
You must pay attention to the moderate water force of 70 – 150 Gallons Per Minute; if the pressure is too enormous, the car will be damaged.
