Car washing is an inevitable thing for vehicles. It's getting hotter and hotter. Car owners should pay attention to it. I believe that many people often wash cars by themselves. What should they pay attention to when washing cars in summer?
1. Don't wash the car with cold water in summer
The temperature in summer is very high. If the weather temperature is 30 degrees, the temperature of the car body may reach 50 or 60 degrees in the mid afternoon, or it may be higher. If the car is driven at a high speed or exposed to the sun, if it is washed with cold water, it will cause serious damage to the car's paint surface. If it is serious, it will cause the car's paint to crack. In addition, it may also cause damage to the metal structure in the vehicle, especially the mechanical internal structure. In the most extreme cases, it will crack the metal components, which may affect the driving safety.
2. Washing powder: the car is more damaged by paint
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 washing the car, but some car owners think that adding some washing powder will make the car cleaner in order to clean the car. The other is: we go to some small car washes, and the boss uses washing powder for your benefit. In any case, we need to know that the acid-base level of washing powder or daily cleaning products is different, which is very corrosive to the car paint, so it is suggested that you must use professional car cleaner.
3. Selection of car washing time
We also said the first point, so it's better to suggest that you wash the car sooner or later. If you can't wash the car at noon, you should also avoid washing the car in the strong sunlight. It's very important to find an indoor or sunshade place to wash the car.
4. Remember not to wash the car frequently
Some people will ask, don't wash the car often to keep the car clean? You're wrong, but sometimes it's a bad thing. Because too frequent car washing will accelerate the oxidation of car paint, resulting in the body lose luster, if the car is washed frequently for a long time, the paint will become more and more dim. It's usually best to wash the car once every two weeks or ten days.
5. Don't think it's OK not to wash the car in rainy season
It's good in the north. It often rains in the south. Sometimes it's common for the next ten and a half days in a row. We'll think it's wrong that the rain can clean the car. You should know that rainwater is acidic. If you don't wash it off as soon as possible, it will corrode the paint surface, or even some parts of the chassis, causing faults.
6. Selection of dishcloth
Generally, there are the following types of cloth: microfiber cloth, chamois, artificial chamois cloth and wool cloth. When washing the car, the special towel should be used to clean the car. The special towel will not leave fine fluff on the surface of the car body like the ordinary towel, and the damage to the paint surface of the car is also small. On the glass side, suede fabric is recommended because of its strong ability to remove watermarks. After wiping, the glass will not leave water marks and will not leave fluff to block the vision.
7. Do not wash the overheated brake system directly with water
If you have just finished a mountain run, a long distance or frequent use of brakes, do not immediately flush the brake discs and pads with water. Because the brake disc is very hot after use, flushing immediately may cause the brake disc / disc to burst. Remember this point, after washing the car in winter, you should brake the vehicle in the open space for many times, and try to eliminate the water when washing the car. Otherwise, the brake will fail.
8. Never wash the engine compartment directly with a water gun
Many car owners and friends like to wash the engine compartment with a water gun when washing the car. As has been said before, washing high-temperature objects with cold water will damage or even crack the metal structure of the car, especially the internal structure of the machinery, due to the 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 elements are also waterproof, it is also quite undesirable.
9. Do not spray or wipe directly with high-pressure water gun
Most of the time, the first step in washing the car is to wash it with a high-pressure water gun first, which is not right. If the car body surface is dirty, there will be some small particles of sand attached to the surface. The high-pressure water gun has a lot of pressure, and direct washing will cause friction movement and damage to the car paint. It's better to wash it with water before cleaning.
10. Choose the detergent
Some irregular car wash shops use detergent and other lotions as car wash solution, which will cause the greatest damage to car paint. In fact, the choice of car wash fluid is very knowledgeable. You can't choose acid and alkaline products. It's the most important to choose neutral car wash fluid.
