There is no need to wash the car after the rain? Uncle che teaches you how not to destroy the car!

2020 is destined to be an extraordinary year. Now the whole country has entered the main flood season, and heavy rains have hit cities many times in the Yangtze River basin. There is a saying in ancient poetry that "wind and rain will not change" The air is particularly fresh after the rain, and Uncle Che likes rainy weather. But if it rains heavily, it will spoil the scenery and even cause some natural disasters.

Many car owners like rainy days. For example, Uncle Che's colleague Xiao Qiang hasn't washed his car once since the rainy season. He also said that God made his car "bathe" frequently, so there was no need to reinvent the wheel. Then the question is, should I wash the car after it rains?

First of all, we should know that rain is neither pure water nor distilled water. Water vapor in the air condenses into water droplets, and at the same time it is mixed with pollutants, dust, sulfides and other harmful chemicals in the air. When it falls, it forms rain. If the local air quality is poor, such as the city where you live is a typical industrial city, then it may be acid rain, with low PH value and corrosive acid rain.

Of course, Uncle Che didn't mean to be alarmist. If the acidity is not particularly strong, don't worry too much. The corrosion of acid rain can not be ignored for a long time, and the paint surface may fade obviously. Therefore, Uncle Che suggested that after the rain, let alone going to the car wash shop to spend money to wash the car, it is necessary for him to hit a bucket of clean water and brush the car body. After all, it's not very troublesome. In addition, you need to pay attention to the following points.

Check headlights and circuits.

Yesterday, I told Uncle Che that his taillight was flooded and he wanted to spend money to repair it. He's worried about it. It is not uncommon for lights to get water in rainy days. The water mist in the lamp cavity will change the brightness and direction of light irradiation and affect the driving safety.

Fogging is the most direct basis for judging the water inflow of headlights. Generally, when the temperature in the lamp cavity rises, the water mist will gradually disappear without damage. If you find that the lamp is obviously damaged and the sealing performance is seriously degraded, you should drive to the repair shop /4S shop for timely maintenance and replacement.

In addition, the circuit may be short-circuited when it meets water. There is a saying that the mainstream models listed in recent years are different from the old models and still attach great importance to harness protection. This is the main concern of old cars. When you have to wade, you'd better open the hood, check the circuit equipment and wipe the water.

As a precaution, you'd better check the brake system by the way. Because the braking system has a certain adsorption force, rainwater may be mixed with brake fluid, reducing the boiling point of brake fluid, thus reducing the performance of brake fluid.

In-vehicle dehumidification

When it rains, the air humidity is high, so you'd better turn on the air conditioner, which can not only defog the window, but also reduce the condensation of water vapor in the car. Moreover, it is necessary to clean up the accumulated water in the car in time after the rain stops, otherwise the interior will be easily damp and moldy, and the taste is really bad.

In addition, many riders living in coastal cities always keep dehumidifiers and desiccants at home. These things can be used to dehumidify cars. If it's really troublesome, put a roll of toilet paper. Pay attention to the welding parts of doors, chassis parts and brake discs, which are easy to rust. You can try to clean them after the rain, and then find a cool place to ventilate, but Uncle Che doesn't recommend cleaning them before exposure.

In-vehicle disinfection

It is easy to breed bacteria in the car after rain, so pay special attention to the seats, air conditioning outlets, central control panels and dead corners everywhere. If ignored, it may soon emit odor and affect the health of people inside the car. Uncle Che suggested that you'd better buy a special car interior cleaner online. When cleaning, it is necessary to prevent the liquid from infiltrating into the electronic components inside the center console, and finally wipe it with a dry rag.

Consider waxing (not advertising)

Waxing is the simplest and most effective way to resist the damage of acid rain to car paint. For lasting protection, you can also glaze, both of which can effectively prevent the paint from fading. Of course, you have to spend a little money. If you feel too distressed, forget it. In Uncle Che's view, people feel uncomfortable and want to have a massage. If the car is really your "little lover" and a part of your family, it is not an exaggeration to spend a few hundred dollars on it.

Che Shu's conclusion

Looking at the car "old yellow", my heart must be uncomfortable. Cars are like people, and they don't clean up. Driving out also affects personal image, so proper maintenance after rain is necessary. Let's call it a day. Uncle Che will share more automobile knowledge with you and become an automobile expert in the future. Welcome to leave a message in the comments section. ?
