First of all, it will be obvious that the black car has scratches. Polishing can be handled by hand, which may not have any effect. A polisher is needed, but the paint will definitely be thin after polishing. It will be polished in the same place next time, and the thinner it is, the more it may fall. It is recommended to go to a bigger car wash, and it is best not to go to an automatic car wash, because that brush is very hard, which will damage the paint surface and affect the life of the car paint. As for washing the car in winter, it doesn't have much impact on the car paint. If you love your car, waxing yourself once a week can also protect your car paint. By the way, the whole car paint, especially black paint, is obviously blackened for a long time. If possible, you can buy a light-colored car next time, or buy a white one directly. The scratch is not obvious, and it is resistant to dirt.

Matters needing attention when washing the car:

Detergent is more alkaline, more suitable for removing heavy oil stains, and has no obvious removal effect on bird droppings and gum solidified on the surface of car paint. Because neutral detergent contains more surface active ingredients, it can not only remove the above stains, but also leave a thin protective layer on the paint surface after washing, making the paint surface look brighter.

Drying is very important.

Doing this link is also very important. I believe many car owners have the experience of freezing the back door handle after washing the car in winter. This is because the general car wash only wipes the water on the surface once, and a lot of water will remain in the door, door lock, handle and other parts, which will naturally freeze in cold climate. In fact, the correct way should be to go to the computer to wash the car, because there is a drying program in the computer car wash, and you can also dry the water droplets left in the cracks in the car body, plus artificial supplementary drying, so that the dried car body will not freeze again.

Anti-freezing lock for car washing after snow

It's rainy and snowy this Spring Festival. After driving in the snow, there is a thick layer of slush on the vehicle, chassis and tires. These sludges contain a lot of corrosive substances such as snowmelt agent and acid. If the corrosive substances attached to the chassis cannot be cleaned in time, it will cause serious damage to the paint and chassis. However, most car wash shops have no intention of helping car owners clean these "invisible" parts. It is suggested that car owners should pay full attention to all parts of the car when washing the car in winter.

In addition, don't stop for a long time immediately after washing the car. Might as well let the car run. Because with the start of the car, if there are residual water droplets in the door, they will be thrown out, and there will be heating in the car when driving, which will help dry the residual water in the door and window joints, and the chance of natural freezing will be greatly reduced.
