How to wash the car in the open air in winter without freezing?

1. Indoor car wash shops should be preferred in winter, so that vehicles are not easy to freeze due to high working environment temperature during wiping. In addition, many car wash shops will also provide services to blow away residual moisture with high-pressure air.

For example, the inside of the rearview mirror, the crack of the door and the corner can be cleaned, which is much better than simply drying it with a towel.

2. If the car washing conditions are limited and the cold weather can only be carried out outdoors, some measures should be taken to prevent the vehicle from being frozen. First, in the process of car washing, we should turn on the warm air of the vehicle to keep the interior of the vehicle, especially the windows and doors, in a relatively warm environment.

3. The key parts such as the keyhole of the key should be covered with adhesive tape to avoid freezing after the keyhole enters the water. Once it's frozen, it's hard to turn the key again. Don't use brute force to turn it hard.

Because metal becomes brittle in winter, it is even more troublesome if the key is broken. If the keyhole is frozen, blowing hot air for a while can solve the aim of the blower.

4. Other moving parts on the body, such as doors, windows, skylights, folding rearview mirrors, etc. It may also be frozen by the residual water after washing the car. Because of the large area, it is useless to use a hot hair dryer alone.

But don't thaw it with hot water. Its principle is the same as that of a hot water truck. One is that the temperature changes suddenly, and the other is that it is easy to blow glass. The solution is: move the vehicle to the constant temperature underground garage and thaw it in a warmer place for about ten minutes.

Precautions for car washing:

1, avoid washing the car before the engine is completely cooled, which will lead to premature aging of the engine. Washing the car when the paint is still hot will make the paint shrink when it is cold, and the original smooth paint will become dull and even crack. From the perspective of car beauty, car washing should wait until the car returns to normal temperature, especially after running a long distance. Pay special attention not to wash the car right away.

2. Avoid washing the car under the scorching sun. This will leave traces of dry water droplets on the car body, which will seriously affect the effect after car washing. Whether the owner washes the car himself or goes to a car wash shop, he should be careful not to wash the car in the sun.

3. Avoid using water other than soft water for cleaning, including hot water, alkaline water and high hardness water. Because these substances will damage the paint surface. Cleaning with hard water will leave traces and films on the body surface after drying.

4. Avoid washing the car body with high-pressure water flow. Excessive water pressure will damage the body paint. If there is hard dust and mud on the car body, soak it in water first, and then rinse it with water. Spray with dispersed water.
