In rainy days, in addition to paying attention to driving safety, we should also pay attention to car maintenance.

Rainy days are the most likely to cause car failures, and car maintenance should pay more attention after the rain. Four hidden dangers can't be prevented.

Hidden danger 1: beware of "skin disease" after rain

Some car owners think that "I will wait for rain if I don't wash my car". Actually, car washing is not free when it rains. On the contrary, it should be cleaned after rain, because rain contains a lot of acidic substances, which will corrode the outer bright film of car paint. At the same time, the rain is also mixed with some dust invisible to the naked eye. After being exposed to sunlight (participation, pictures, inquiry), a large number of oxides will be derived. Therefore, it is best to paint your car after the rain. The simple and effective method is waxing, but if you want to achieve lasting protection, you can also seal the glaze.

Hidden danger 2: Beware of engine "qi deficiency"

The engine is the "heart" of the car, which is the most important and the most prone to problems. After the rain, the automobile engine is "weak" and it is difficult to start, which may be because the ignition system is damp or aging. Once the ignition system is found to be damp, resulting in poor ignition and engine performance degradation, dry the inside and outside of the distributor and wires temporarily with a dry cloth; If it is due to aging or leakage, it must be replaced in time.

Hidden danger 3: Beware of headlights "cataract"

Driving in rainy days is easy to cause headlights to enter the water, which not only affects the brightness, but also changes the irradiation direction of headlights, which brings hidden dangers to driving safety. If water mist is found in the lamp after rain, turn on the headlights and high beam at the same time, and observe whether the water mist disappears in the lamp after one hour. If it disappears, it is that the lamp holder is not tightly sealed and causes water leakage; If the water mist does not disperse, there may be a problem with the adhesion of the big lampshade. You need to clean up the adhesion of the lampshade, air-dry it and glue it, or you can choose to go to a professional repair shop for repair.

Hidden danger 4: ventilation and purification to remove the "source of disease"

After a rainy day, the car often smells musty. In this case, you can turn the warm air to the maximum and turn it on for about 20 minutes, so that the water in the car can evaporate quickly. Or open the door and trunk in the sun to thoroughly ventilate and dehumidify. It's best not to cover up the musty smell with perfume, because some musty smells are caused by perfume, such as acidic lemon perfume, which is more likely to be moldy and stale after it is emitted.
