The oil stain of range hood is a mixture of various oils and impurities plus water. When cooking, vegetable oil, animal oil, salt, sauce, vinegar and water volatilize and are pumped out by the range hood, and some stick to the range hood and drop into the oil pan or underground.
The range hood on the car body is oily, so it can't be wiped dry. Scrub it with water, and the impurities in the oil will scratch the car paint. Gently wash it off with a cotton ball or soft brush dipped in gasoline or lipophilic cleaner. Because oil stains contain salt, sauce and vinegar, they may be corrosive to car paint. Oil stains left on it for a long time may corrode the paint surface, and there may be some traces after washing.
The use of car wash mud:
When using car wash mud, it is necessary to cooperate with clean water and car wash as lubricants, which can not only achieve the lubrication effect, but also form a film on the paint surface, effectively isolate the car wash mud from the car paint, and also achieve the lubrication effect, ensuring that the car wash mud grinds impurities instead of the paint surface.
Remember: there are silt or impurities in use, which need to be treated or stopped in time. Car wash mud with sediment will wear the car paint.
Car wash mud can be roughly divided into ordinary, neutral and strength decontamination according to viscosity strength. Because this mud has a certain viscosity, some water should be attached during car washing. This can prevent the car wash mud from sticking to the car body. If the car wash mud sticks to the car body or hands during application, you can stick it back with a large piece of car wash mud. Because of the good affinity between mud and mud, we can use this characteristic to stick it back.
