A new white car with a black watermark when it rains.

The white car is obvious. Many friends choose to buy a white car, but it is easier to get dirty. So many white car buyers have encountered such a thing. I just bought a new milky white car, and there is a black watermark on the surface after it rains. What is the reason? How to remove it?

The black watermark in the white car is mainly caused by calcium hydroxide carried by precipitation falling into the car, and generally appears on laminated glass. If it is not cleaned for a long time after rain, it is actually calcium hydroxide. For the water stains in the white car, professional cleaning products can be used to remove them, such as water stain cleaning solution, decontamination wax or car wash mud.

In view of the water mark, you can try to clean it with a rag or sponge wet cleaner first. If it can't be washed off, it means that the watermark has penetrated into the paint surface and can only be solved by polishing. You can use a polisher or car wash mud. However, it must be noted that although polishing can remove difficult water stains, it is actually exhausting maintenance. Polishing will reduce the thickness of the paint surface, so the smaller the polishing frequency, the higher it will be. If necessary, it is recommended to polish it in a professional beauty salon to prevent the paint surface from being damaged.

Usually, car maintenance must be on time, and at the same time, attention should be paid to paint maintenance. If the car is dirty, it should be cleaned on time. After the car wash shop, you can also choose to wax the car. Polishing and waxing can produce a layer of wax on the body surface, which plays a protective role. In addition, if there are standards, you can also choose car glaze, surface coating or car crystal plating. This new project can maintain the paint surface faster.
