Does washing the car with a high pressure water gun damage the paint?

The high-pressure water gun will damage the car paint. When the high-pressure water gun is used to wash the car, if the water pressure is too high and the operation is improper, it is easy to scratch the surface of the car with the sand and gravel on the car. Causes abnormal wear of the paint. If the car paint itself is a little broken, the high-pressure water gun will also widen the wound, and even wash off the wax, crystal, and coating. Here are some tips for washing your car:

The car should be washed with a pre-wash procedure before washing the car, that is, use professional equipment to spray special pre-wash liquid on the body and wait for a minute or two. After soaking, most of the sand can be separated from the car paint, and then rinsed with a water gun;

2. The car should be washed in order: the car washing sequence is the roof, hood, and trunk lid with less dust and sand. The method of cleaning from top to bottom can prevent scratches, and scrub in the same direction;

3. Select the appropriate water temperature: After the car has been running for a period of time, the car is in a high temperature state, and it is not suitable to use cold water to clean it. Even if you want to clean a car that has not been driven for a long time, if the car body has been exposed to the sun for a certain period of time, immediately wash the car with cold water, the characteristics of thermal expansion and cold contraction will easily cause the aging of the car paint;

4. Don't try hard when washing tires: There are often a lot of dirt, leaves and other stains on the wheel rims and tires. You should buy an acid solvent specially designed for washing wheels, first apply a little bit with a soft cloth, and then rinse with clean water mixed with car wash;
