10 car washing taboo in summer

When summer comes, we will wash the car more often. Many friends just don't want to see their cars dirty, even if there is a little dust, they should clean them. This is good, but sometimes the behavior of the owner will become the behavior of car injury. Whether you want your own car for five years, such as a new car, a new car, depends on you. Then, here are some things to pay attention to when washing the car.

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

In summer, the temperature is high. If the weather temperature is 30 degrees, the body temperature may reach 50-60 degrees or even higher at noon and afternoon. If you wash the car with cold water, it will cause serious damage to the paint surface (especially to the scratched paint surface that has just been repaired), which will lead to cracking of the paint surface in serious cases. In addition, it may damage the metal structure in the car, especially the internal structure of the machine. In the most extreme case, it may lead to cracks in metal parts and affect driving safety.

2. Washing powder This car is more harmful to car paint.

There are two kinds of such situations. One is: we try to save ourselves trouble and wash our cars at home. We also advocate this way of car washing. However, in order to clean the car, 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, we 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.

3. 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, you should avoid washing your car in strong sunlight. It is very important to find an indoor or shady place to wash the car.

Remember not to wash the car often.

Some people may ask, isn't washing the car often to keep the car clean? You are wrong, but sometimes good things can be bad. 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 once every two weeks or ten days.

Don't think you don't have to wash your car in rainy season?

Fortunately, it often rains in the north and south, sometimes for ten days and a half months. We will think that rain can wash cars, which is wrong. Note 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, leading to failure.

6. Selection of rags

There are generally the following kinds of automobile cleaning cloths: superfine fiber automobile cleaning cloths, suede/artificial suede automobile cleaning cloths and wool automobile cleaning cloths. When washing the car, use a special towel to wash the car. The special towel for car washing will not leave fine fluff on the surface of the car body like ordinary towels, and the damage to the car paint surface is also very small. On the other hand, it is suggested to use suede cloth for glass, because suede has a strong ability to remove watermarks. Will the polished glass leave water marks and be blocked by residual fluff?

7. Don't directly flush the overheated braking system with water.

If you just run on a mountain road, use the brakes for a long time or frequently, and don't wash the brake discs and brake pads with water immediately. Because the brake disc is very hot after use, washing it with water immediately may cause the brake disc/brake disc to break. Remember this. After washing the car in winter, brake many times in the air to eliminate the accumulated water when washing the car as much as possible. Otherwise, the brakes will fail. 8. 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, objects heated with cold water will damage the metal structure of the car, especially the internal structure of the machine, and even crack due to huge temperature difference. So it is quite unscientific to cool the engine in this way. If you want to wash the engine compartment directly with water for convenience, although these electronic control components are also waterproof, it is quite undesirable.

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

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

10. Select the cleaner.

Some informal car wash shops use detergents 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, and you can't choose acidic and highly alkaline products. Choosing a neutral car wash solution is the most important.
