What are the precautions for washing your own car?

Precautions for washing your own car: 1. When washing a car, you should generally put a layer of foam on the car, but be careful not to use washing powder, which is an alkaline cleaner and does great harm to the car paint. If you wash your car with washing powder for a long time, the body will slowly lose its luster. 2. When cleaning the car, the cleaning cloth should be soft and slightly wet. When washing the car, don't choose the noon with strong sunshine. Strong sunlight can make the water on the car evaporate faster, but it will also accelerate the damage of the car paint. 4. The interior of the car is mostly wrapped by textiles and leather, and special internal cleaning agents should be used for cleaning. In addition, when the interior cannot be cleaned by itself, you should go to a professional car wash shop to clean it.
