An experienced car wash master will tell his disciples what is the best way to wash a car in winter.

It is best to wash the car in winter with cold water. Because warm water freezes faster than cold water, it will freeze immediately if it sticks to the carriage; Salt water will corrode vehicles; Glass water is more suitable for cleaning glass. Don't stop there after washing the car in winter. Drive around as much as possible. When washing cars, water may enter the handbrake line. If the car is parked there, the handbrake line may freeze.

When washing the car in winter, it is best not to wash the cracked parts in the car with a pistol, such as door handles, doors and windows, exhaust pipes, etc. If the outdoor temperature is too high, it will be all right. If it is too low, freezing in these places will greatly affect the use. The most important thing is to wash the car in time after rain and snow. Many people think that rain and snow are equivalent to saving money for a car wash. In fact, rain and snow still have some corrosive components, especially car chassis. When driving in rain and snow, a lot of dirt will remain on the chassis, which will corrode the surface of the car over time.

Matters needing attention

1, avoid washing the car in the hot sun. This will leave traces of dry water droplets on the car body, which will seriously affect the effect after car washing. Whether the owner washes the car himself or goes to a car wash shop, he should be careful not to wash the car in the sun.

2. Avoid using water other than soft water for cleaning, including hot water, alkaline water and high hardness water. Because these substances will damage the paint surface. Cleaning with hard water will leave traces and films on the body surface after drying.

3. Avoid washing the car body with high-pressure water flow. Excessive water pressure will damage the body paint. If there is hard dust and mud on the car body, soak it in water first, and then rinse it with water. Spray with dispersed water.

4. Avoid adding detergent. Washing powder, washing powder and inferior soap are not allowed to be used during cleaning. Because these detergents contain alkali, they may wash off the grease in the car paint and accelerate the aging of the car paint. Washing cars generally does not add detergent.
