Sometimes it's possible to go on a business trip or something else, causing a car to leave idle, a long car rusting and aging all for you. The corrosion of the car is mainly caused by the joint effect of moisture, oxygen and corrosive substances in the air. Therefore, the metal surface should be kept clean for vehicles which are suspended for a long time. Prevent the rust of the car from aging. The garage should be kept ventilated to keep the relative humidity below 70. It is necessary to remove dust, dirt and moisture on the car in time. Oil and grease or oil paper should be applied to rust prone areas and parts. For each assembly, the pores should be sealed to prevent air, moisture and dust from entering the interior. Rubber products on cars, such as tires, drive belts and dustproof cover, often suffer from aging, expansion or form phenomenon, resulting in deteriorating performance and shorter service life. Like rubber products aging, mainly because rubber belongs to unsaturated polymer hydrocarbons, easy to absorb oxygen in the air and oxidize, and vulcanized rubber also has certain air permeability, oxygen is easy to enter the internal oxidation. In particular, direct sunlight can make rubber rapidly aging. Rubber products contaminated by gasoline and oil will cause volume expansion, loose gum and elasticity. To prevent the aging of rubber products, direct sunlight exposure and mineral oil contact should be avoided. The cushions and carpets are easy to absorb water. Especially in damp areas and rainy seasons, it is more susceptible to damp and mildew. Therefore, owners should check the cotton and linen products on the vehicle regularly, dry them in time, and keep them dry. The antiknock performance of gasoline depends on the octane number of gasoline. The gasoline octane number will decrease with the loss of light components and the increase of colloid content, so that its antiknock ability will decrease. Therefore, the gasoline tank should be tightly sealed and avoid excessive temperature. The best time for gasoline storage is not to be too long. Start engine at least once a month, idle 4-5min, check engine operation. If there are abnormal phenomena, it is necessary to adjust and repair in time. In addition, the battery should be checked regularly. The electrolyte level of the battery must be 10-15mm higher than that of the plate. When distilled water should be added in time, the battery should be kept sufficient and the battery should be charged if necessary.
