Matters needing attention in car washing in summer

Car washing is the most basic car maintenance. Let me introduce the precautions for car washing in summer, hoping to help you!

1. Remember not to wash your car with cold water in summer.

The temperature in summer itself is very high. If the weather temperature is 30 degrees, the body temperature may reach 50 degrees, 60 degrees or even higher in the middle and afternoon. If the vehicle is washed with cold water, it will cause serious damage to the paint surface (which has a great impact on the scratched paint surface that has just been repaired), and in severe cases, it will lead to the paint surface cracking. In addition, it may also cause damage to the metal structure in the car, especially the internal structure of the machine. In the most extreme case, it will cause cracks in metal parts, which is likely to affect driving safety.

2. Selection of car washing time period

We also said the first point, so we'd better advise you to wash the car in the morning and evening. If you can't wash your car at noon, avoid washing your car in strong sunlight. It is very important to find an indoor or shady place to wash the car.

Don't think you can not wash your car in the rainy season.

It's okay in the north, but it often rains in the south. Sometimes it rains for ten and a half months in a row. We will think that rain can wash cars, which is wrong. You should know that rain is acidic. If it is not washed off as soon as possible, it will corrode the paint surface and even some parts of the chassis, resulting in failure.

4. Never rinse the overheated braking system directly with water.

If you only run on mountain roads, long distances or frequently, don't wash the brake discs and brake pads with water immediately after using the brakes. Because the brake disc is very hot after use, washing it with water immediately may cause the brake disc/brake disc to burst. What needs to be remembered is that after washing the car in winter, the vehicle should brake many times in an open place to remove the accumulated water when washing the car as much as possible. Otherwise, the brakes will fail.

5. Don't spray it directly with a high-pressure water gun or wipe it with a rag.

Many times, the first step in washing a car is to wash it with a high-pressure water gun, which is not right. If the surface of the car body is dirty, some small sandstone will be attached to the surface, and the pressure of the high-pressure water gun is great. Direct washing will cause friction movement and damage the car paint. It is best to rinse with clean water before cleaning.

6. Washing powder This car hurts paint even more.

There are two kinds of situations. One is that we try to save trouble and wash the car at home. We also advocate this way of car washing, but some car owners think that adding washing powder will make the car cleaner. The other is: we go to some small car wash shops, and the boss gives you washing powder for profit. In any case, you should know that the pH of washing powder or daily cleaning products is different, which is very corrosive to car paint, so we suggest that you must use professional car cleaner here.

7. Remember not to wash the car frequently.

Some people may ask, isn't it possible to keep the car clean by washing the car often? You are wrong, but sometimes it is a bad thing. Because too frequent car washing will accelerate the oxidation of car paint, resulting in the loss of luster of the car body. If you wash your car frequently for a long time, the paint will get dimmer and dimmer. It is generally best to wash the car every two weeks or ten days.

8. Selection of rags

Generally, there are the following kinds of cleaning cloths: microfiber cleaning cloths, suede/artificial suede cleaning cloths and wool cleaning cloths. When washing the car, you should use the towel specially used for washing the car. The special towel for car washing will not leave fine fluff on the surface of the car body like ordinary towels, and it will also cause less damage to the paint surface of the car. For glass, it is recommended to use suede flannel, because suede has a strong ability to remove watermarks. After wiping, the glass will not leave water marks, but it will also leave fluff to obstruct the line of sight.

9. Remember not to directly flush the engine compartment with a water gun.

Many car owners like to wash the engine compartment with a water gun when washing the car. As mentioned above, cleaning high-temperature objects with cold water will cause damage to the metal structure of the car, especially the internal structure of the machine, and even crack. So it is quite unscientific to try to cool the engine in this way. If you want to directly flush the engine compartment with water, although these electronic control elements are also waterproof, they are quite undesirable.

10. Choose the right detergent.

Some informal car wash shops use lotion such as detergent as car wash liquid to wash cars, which is the most harmful to car paint. In fact, the choice of car wash liquid is very knowledgeable. Can't choose acidic and alkaline products. Choosing a neutral car wash liquid is the most important.
