The car's paint is as fragile as the human skin. The car paint surface is stained with many things and it can be scratched. If our skin is not maintained or care, it will cause acne, and the car paint will not be maintained. There will be a series of problems such as cracks, so we need some knowledge of car maintenance.

1. Prevent metal rust Corrosion is mainly caused by the joint action of moisture, oxygen, and corrosive substances in the air. Therefore, for long-term parked cars, the metal surface should be kept clean. Parking garages should always be ventilated to keep the relative humidity below 70%.

Remove dust, dirt, and moisture from the car in a timely manner. The rust-prone parts and the surfaces of the parts should be coated with oil, grease or wrap. The pores in each assembly should be sealed to prevent air, moisture and dust from entering the interior.

2. Prevent deterioration of rubber products Rubber products on automobiles, such as tires, transmission belts, and dust covers, often undergo aging, swelling, or deformation, resulting in deteriorated performance and shorter service life.

The aging of rubber products is mainly due to the fact that rubber is an unsaturated polymer hydrocarbon that easily absorbs oxygen from the air and oxidizes. At the same time, vulcanized rubber has a certain degree of air permeability, and oxygen easily enters the interior to cause oxidation. Especially direct sunlight can promote rapid aging of rubber. After rubber products are contaminated with gasoline and engine oil, they will cause volume expansion, loosening gums, and reduced elasticity.

In order to prevent the aging of rubber products, direct sunlight and mineral oil contact should be avoided.
