There are two main aspects of vehicle maintenance, one is the compulsory maintenance provided by the maintenance station for you. On the other hand, the owner does some daily maintenance by himself. The normal maintenance of the vehicle is related to the service life of the vehicle and the safety of the driver and passengers. Improper maintenance or use will cause vehicle failure and bring safety risks. In addition to mandatory maintenance at our maintenance station on time, we should also do daily maintenance work, which is beneficial to the "health" of the vehicle. To keep your car in good running condition, you benefit from careful daily maintenance.

After the purchase of the car, please carefully read the "Product quality Guarantee Certificate" and "Instruction manual", in the "instruction manual" there are detailed use precautions and maintenance methods, you should carefully read and comply with it to ensure that the vehicle is in good use condition. Introduce the common sense of vehicle maintenance, hope to provide you with some help.

Car paint maintenance common sense is actually very complicated. Although the car paint looks smooth, but the surface has small concave and holes, the new car is recommended to do a sealing glaze or coating treatment. Under normal circumstances, the coating is longer than the sealing glaze, the sealing glaze effect is about 3 months to half a year, the coating is more than half a year, and it is recommended that a second sealing glaze or coating be carried out after a certain time. A routine item at a car wash is polishing and waxing. However, these two items should be done under the premise of coating or sealing glaze, because it is always waxed or polished, which is equivalent to consuming the thickness of the paint, gradually thinning the paint, losing luster, and appearing small scratches.

Car paint maintenance daily need to pay attention to a lot of. First, avoid wiping the paint directly with a duster or dry cloth, wash the dust and dirt on the surface of the car with water, wipe it clean with a clean absorbent cloth, and do not dry it by itself after flushing. Second, the parking should be considered to avoid long-term exposure to the sun, especially white and non-metallic paint. Three, reduce the number of car washes, and try not to do vehicle waxing and polishing. Four, pay attention to the timely removal of corrosive things such as bird droppings. Fifth, pay attention to reducing to corrosive areas, such as the seaside, the road surface with snowmelt agent, the newly paved asphalt road, etc. Sixth, after running at high speed in summer, the insect body hit by the front of the vehicle should be cleaned in time, if not cleaned in time, the paint of the vehicle will be corroded in a very short time.

Car tires and steel rings are the most easily dirty parts. Therefore, the maintenance of tires is also a very important key. Before washing the tires, prepare a brush with a long handle, and if the tires are not too dirty, wash them with a regular detergent. Unless there's really too much dirt, then you might want to buy a professional cleaner.

The brush should not be used on chrome-plated mirror treated rims, which will leave obvious scars. Chrome-plated wheels generally use a sponge, wash small places and then consider using a brush. As long as the tire and knee parts are cleaned, the whole car will look like optical fiber bright
