What details should I pay attention to when washing the car?

Automobile cleaning is a very important link in the process of automobile maintenance, which is often ignored. Improper car washing may lead to accelerated aging of car clothes or car paint, causing irreversible damage. What details should I pay special attention to when washing the car?

First, avoid frequent car washing. If the car is washed too frequently, the lines generated by towel friction will increase, and the paint surface will age due to water quality and reagent factors. It is not good to wash for a long time. There are acidic components in rain and snow, and substances such as bird droppings, dust, chewing gum and air-conditioning water will also corrode car clothes or car paints. Suggest cleaning 2~ times a month? About three times. This is a relative choice.

Second, wash the car in time after rain and snow. Rain or snow water is mostly acidic and corrosive to car paint. If it encounters rain and snow and is not cleaned in time, the acidic substances in the rain and snow will slowly corrode the bright film outside the car paint, resulting in the aging of the car paint becoming dull. When washing the car, the bottom of the car should also be cleaned. Rain and snow will splash on the bottom of the car and mix with the sediment attached to the bottom of the car, which will easily corrode the surface of the parts, and then lead to rust or aging of the parts.

Third, wait for the engine to cool before washing the car. After running at high speed and driving for a long time, it is not advisable to wash the car immediately. Washing the car when the engine is not cold may damage the metal or plastic parts of the engine. When the brake pads of the brake disc are cooled again under relatively hot conditions, the huge temperature difference may lead to deformation. It's best to wait for the car to return to normal temperature before washing.

Fourth, pay attention to the order of car washing. Wash the car body with slow water first to soften most of the dirt or other substances attached to the car surface, then spray a cleaning agent, and wait for one to two minutes before washing with soft water. Spray the car wash liquid for the second time, then wipe off the residual stains and fine dust from top to bottom with a towel or sponge, and finally rinse it with a water gun. (? The process of different stores is slightly different, so there is no need to over-interpret it)

Finally, it is suggested that the regular high-end car wash shop should be the first choice for car washing, and the car should be placed there. Process specification, solid materials, clean in place. One word is "really at ease".

Most car owners still choose to wash their cars in a car wash shop with standardized behavior because of factors such as queuing time, travel distance, price budget and attention. There are several suggestions: First, tell the car washer to wash the towel twice frequently in the process of wiping with a rag after spraying the car wash liquid to avoid the fine sand deposited on the towel from damaging the car paint. Second, let him open the engine room and blow it with a pump to blow off some weeds, leaves or dust in the engine room, protect the engine room environment, and ensure heat dissipation and cleanliness of all components. Third, let him clean up the debris and dust in the small space under the seat. You don't want dust and bacteria in your car, do you? This will not only get twice the result with half the effort, but also require no effort.
