Many drivers who drive semi-trailers see that their car is dirty, they will "bath" the semi-trailer and do some cleaning and maintenance, but do you know the problems that should be paid attention to when cleaning the semi-trailer? Today, the editor will take you to understand the matters that should be paid attention to when cleaning the semi-trailer.
1. Avoid washing the car before the engine of the semi-trailer is completely cooled down. This will cause the engine to age prematurely.
2. Avoid washing the semi-trailer under the hot sun. This will leave dry bead marks on the body.
3. Avoid washing semi-trailers in very cold weather. Once the water freezes, it will cause the paint film to crack.
Fourth, avoid using water other than soft water to clean the semi-trailer, including hot water, alkaline water and water with higher hardness. Because these substances can damage the paint, wash with hard water and leave marks and films on the surface of the car after drying.
Five, avoid using high-pressure water to wash the semi-trailer body. Excessive water pressure will damage the car body paint. If there is hard dust and mud on the car body, soak it with water first, and then rinse it with water. Apply a dispersing stream of water to spray.
Sixth, avoid adding detergent indiscriminately. Washing powder, stain remover powder and poor quality soap are not allowed when washing. Because these cleaners contain alkalis, it may wash away grease from the paint surface and accelerate the aging of the paint surface. Generally do not add detergent when washing the car.
Seven, avoid rubbing. After rinsing with water, many people like to wipe it; there are two main problems with wiping: the cloth used is not qualified and the wiping method is wrong. To wipe, use a soft cloth or a soft, clean sponge. When wiping, it should be gently wiped from top to bottom along the direction of the water flow, and cannot be rubbed in circles or horizontally.
Eight, avoid using hard cleaning tools to remove dirt. Such as plastic brushes, blades to scrape the stains, which can easily damage the paint surface.
9. Do not touch the surface of the car body with dirty hands stained with oil, or place oily tools or wipes containing organic solvents on the car body, which will easily leave marks on the paint surface or cause the paint surface to fade prematurely.
