Do you want to use the automatic car wash at the gas station? These are some precautions.

1, the damage of automatic car washing machine to car paint is definitely greater than that of manual car washing.

The cleaning device of automatic car washing machine is a large roller assembled with EVA sponge strips. The roller rotates at high speed, so that the sponge strips rub against the car body and wash away the stains. I tried to feel it specially. The surface of this sponge strip is very smooth, and it is easy to leave scratches on the car paint as long as there are a little particles on the contact surface when it comes into contact with the car body. In addition, the shape of each car is different, so these rollers are movable. According to the shape of the car body, they change positions and cling to the car body brush. The contact force is definitely much greater than that of manual wiping with a rag.

Manual car washing is less harmful to car paint, because the towel is used for manual car washing, and there are many wrinkles and pores on the surface of the towel, which can wrap particles and try to avoid direct friction between particles and car paint. In addition, the wiping force can also be properly controlled when washing the car manually. So the damage to the car paint is very small.

2. Matters needing attention in the use of automatic car washer

I think this is very important, because this machine is automatic car washing, and no one has ever operated it. If you don't know how to use it, some wrong operations in car washing are likely to lead to more serious consequences. Below, I will share with you some precautions for the use of automatic car washing machines.

(1) Don't turn off the engine when washing the car.

Because there will be nozzles spraying water on the car body when washing the car, some models may spray water on the air intake. If you turn off the engine during car washing, it will be difficult for you to detect whether water enters the air cleaner element along the air inlet. Ignition after car washing will suck water into the cylinder, which is equivalent to starting again after wading and flameout, which will cause serious damage to the engine.

There is no risk of idling when washing the car, because if water enters the cylinder at this time, it will cause the engine to stall for a while. At this time, you can get an early warning to avoid damaging the engine during the second start.

(2) Don't step on the brakes when washing the car.

At present, many automatic car washes are running. There is a conveyor belt in the car wash tunnel. The left wheel of the vehicle runs on the conveyor belt and is pushed forward by the conveyor belt, while the right wheel rolls on the ground. If you step on the brakes, the right wheel will go slowly and the left wheel will go fast, which will easily push off the car body and even cause the vehicle to hit the car washing equipment seriously.

(3) Don't hit the direction when washing the car.

The reason is the same, because the left wheel is on the conveyor belt and the right wheel is on the ground. If you hit the direction, the right wheel will move the car body to the right, and it is easy to hit the car washing equipment.

(4) Don't turn on the wiper when washing the car.

When washing the car, the big roller rotates at high speed with sponge strips and brushes them on your windshield. If the wiper is turned on at this time, it is easy to make the sponge strip wrap around the wiper arm. Judging from the strength of the robot arm of the car washer, the wiper arm is easy to bend.

(5) Turn off the automatic hold function.

This is a point that many car owners easily overlook. Remember to turn off the automatic hold function when using the automatic car washer. Otherwise, when you get on the conveyor belt, it will automatically help you brake, and the conveyor belt starter car will be pulled away.

But now there is a non-contact automatic car wash. In the process of car washing, the vehicle does not need to move. The machine will spray cleaning agent around the car body and then wash away the stains with high-pressure water. The whole process does not touch the car body. This kind of equipment is relatively simple to use and there is no need to worry about any danger.

The advantage of automatic car washing is that it is very convenient and saves time. Although the damage to car paint is slightly greater than hand washing, it is only relative and not completely unusable. It doesn't make much difference if you don't look carefully after washing. Generally speaking, most people can accept it. However, it is necessary to take special care of vehicles. It is not recommended to wax and polish at both ends for three days and stick invisible car clothes.
