When washing the car, use a special cleaning agent for car washing, and the cleaning agent containing water wax is the best. The PH value of professional cleaning agents should be neutral and will not corrode the surface of automobiles. If it contains water wax, it can give the body a moisturizing effect when washing the car, even if it is washed frequently, it will not damage the car paint, and the effect is very ideal.

Don't use alkaline detergent or soap powder to wash the car, because although they have strong detergency, they do great harm to the car body. They are often used to wash cars, and the light on the surface of the car body will soon be eroded; But also accelerate the aging of rubber parts, tires, windows and so on.
