Talking about car washing.

In the hot summer, all parts of the country are receiving high temperature roasting. In order to cool down their cars, huge car owners take a cold bath every three or five times. But washing cars in summer is slightly different from washing cars in other seasons. A little carelessness may hurt the car! Next, I'll talk to you about some taboos about washing cars in summer.

First of all, you can't wash the car immediately after high temperature exposure, because the temperature of the car body and car glass is very high under high temperature exposure. If washed directly with cold water, the overheated automobile glass will expand with heat and contract with cold, and the automobile glass will crack or even burst.

In addition, the paint is in a state of high temperature expansion after exposure. If you wash the car with cold water immediately, the huge temperature difference will stimulate the car paint and cause it to crack. Moreover, after the car continues to drive, the engine, brakes and other systems are in a high temperature state, especially in summer, the temperature is higher. If cold water is suddenly used at this time, it will cause great damage to the structure of the car, especially the deformation of the brake disc.

Therefore, when the car is exposed to the sun, it should be parked in the shade first, and then cleaned after it is cooled to normal temperature. Before washing the car, we can also spray the car body glass with normal temperature water, which can buffer the temperature drop of the glass and reduce the influence of temperature difference on the car glass.

Secondly, when we wash the car in summer, we'd better choose to wash it early and wash it late, and try to avoid washing the car in the hot sun at noon. Although washing the car in the hot sun, it will soon dry. But when you get off in the hot sun, the water drops on your body are equivalent to convex lenses. Strong light will pass through the convex lens to concentrate heat on the car body, and the car paint will gradually lose its luster at this high temperature.

We wash the car in summer, not after high temperature exposure, nor can we use rain instead of washing the car. Because rainwater contains acidic substances, if it is attached for a long time, it will not only damage the car paint, but even corrode some parts of the chassis. Moreover, the cleaning power of rainwater on vehicles is limited, and it is easier to attach sediment. So after the rain, everyone must wash the car quickly.

In addition, when we wash the car in summer, don't wash it directly with a high-pressure water gun. Although it is time-saving and labor-saving, a lot of dust is attached to the surface of the car. If washed directly with a high-pressure water gun, these grains of sand will wear the paint surface. And when we wash the car, don't wash it directly with washing powder. Cars also have special car wash fluids.

The pH value of washing powder or daily cleaning products may not be suitable for car paint. If you don't use it well, it will corrode the car paint, and in the long run it will disfigure your face! So don't wash your car with washing powder to save money. Car washing is also a science. If the car washing method is wrong, it will do great harm to the car.
