Is automatic car washing harmful to car paint?

If we want to discuss whether car washing machines are harmful to car paint, we should sort out the types of car washing machines. We often see nothing more than two kinds. One is a contactless automatic car washer, and the other is a brush automatic car washer.

Contactless automatic car washing machine

Non-contact automatic car washing machine uses three-dimensional high-pressure nozzle to clean the dirt on the vehicle surface. It is advertised as a car washer that won't damage the car paint. If the pressure of the water gun is greater than 7MP, the particles attached to the surface of the car will scratch the car body under the scouring of the high-pressure water gun. Therefore, in order to protect the car paint, the pressure of the water gun is not high, generally around 5MP, which makes it difficult for this car washer to clean the car. After washing the car, our habit is to dry it. Even if the towel in the handyman's hand is clean, the dirt on the car body will make the car paint inevitable.

Brush automatic car washer

Brush automatic car washing machine is the most common one in daily car washing, which uses roller brush to clean the car surface. Because of computer programming control, it has the advantages of uniform brushing pressure and stable car washing speed and direction. But washing the car will also press the particles on the car body and scratch the car paint.
