There are several misunderstandings about car washing, and we should pay attention to the paint of c

There are several major misunderstandings about washing the car by yourself, which is easy for novice drivers to make, and it is very damaging to the body.

The summer sun is very damaging to the skin, and it is no less damaging to the car. For example, milky white car paint will have a more obvious yellowing condition after a long period of exposure, and at the same time, it will also make the car paint dull. For example, in the southern region, in addition to the exposure to the sun, there are also heavy rainstorms in summer, not to mention whether the car will be soaked, and the accumulation of acid and alkaline rain will also have a corrosive effect on the car paint.

In addition to the paint, summer exposure to the rubber position of the vehicle will also bring harm, such as panoramic sunroof, door window glass and other parts are rubber strips to maintain the vehicle, long-term exposure will accelerate the aging of rubber, the occurrence of aging hard bottoming, <>

Not only does this rubber lose its buffering and sealing properties, but it can also cause rainwater to seep into the car. After the vehicle is exposed to the sun, whether there is a smell of plastic when it is opened, there are many decorations on the instrument panel that are all plastic, and the sun will speed up their old position, and the door window glass panoramic sunroof has rubber strips, and long-term exposure to the sun will also crack and age, endangering the airtightness, and there will be rainwater seeping in on rainy days. There are also plastic products that will release indoor formaldehyde through exposure to the sun, which will affect people's health when they stay in the room.

Car paint is generally divided into four layers: electrophoretic layer, topcoat layer, varnish layer, and topcoat layer. There is a difference between the original paint and the spray paint after the injury.

The paint that is sprayed after is basically only clear coat and top coat. The original car paint is all high-temperature paint of nearly 200°, and the topcoat layer can effectively prevent direct UV rays, and the high ambient temperature in summer is basically not a problem. The paint sprayed after is tempered at 60° in the car paint room, but the topcoat used in the general car paint room is relatively cheap, and the resistance to ultraviolet rays is much worse.

Exposure to the sun for a long time will not only damage the car paint, but also have a great harm to the car interior and its dashboard.

First of all, the temperature in the car rises rapidly after sun exposure, and the ambient temperature of the seat can reach sixty or seventy degrees; Secondly, because of the exposure to the sun, many harmful substances will be produced in the car, which endangers the health of the staff in the car; Moreover, it is easy to cause premature aging of the car interior and instrument panel. After getting into the car, the panoramic sunroof and window glass will be used to start the car (no need to blow the air conditioner at this time), so that the temperature in the car can quickly drop to a balance with the external environment according to the flow of air during driving, and the learning process must only take one or two minutes. Then turn on the air conditioner so that the vents are blowing upwards, and change the air conditioning cycle to the in-car cycle.

Generally, exposure to the sun after washing the car will not cause damage to the car paint, but it should be noted that the car cannot be used with cold water at a low temperature at noon, which may cause the car paint to crack or even damage the metal structure in the car.

Yes. Because the car is often washed in summer and exposed to the sun, the car paint will be aged, so the car paint will be damaged.

In summer, the car is often washed, and the sun is often exposed to the sun, which has no effect on the car paint. Just don't wash your car with sea salt water when you wash it.

First of all, in the summer, the car cannot be washed after being exposed to the sun, the vehicle is driven outdoors, baked by high temperatures, and the surface temperature of the body is very high. If you wash your car with cold water, it will cause a lot of damage to the surface of the car paint, which is likely to cause cracks and bumps in the car paint. In addition, the parts of the machine in the car will also be affected.

The difference in high temperature may cause cracks in metal parts, which can affect normal driving.

Secondly, don't wash your car in the sun or bask in the sun after washing it, many car owners think that this will make the car dry faster, but this is actually the wrong approach. First, high temperature exposure is not good for people, and the water droplets left on the car are like a convex mirror, which will concentrate on the car paint under the irradiation of the sun and damage the car paint. And because the evaporation of water droplets will cause uneven heating of the body, the temperature of the local position is too high, and it is easy to damage the paint and discolor after a long time.

It is recommended to wash the car in the morning or evening, the sun is not so hot, it is good for both people and the car.

Also, don't wash your car too often. As we all know, the clothes will fade after washing too much, of course, washing more cars is not good for car paint, if waxing or crystal car, washing too much will lose the surface protective layer, without protection will accelerate the aging of car paint, it is recommended to wash once in ten days and half a month, because it is not good to wash in the car wash shop, it is said that it costs money.

Moreover, the surface paint of many cars is very thin, because long-term exposure to sunlight will damage the car paint, causing the paint to crack, protrude or even peel off, affecting the appearance of the car. Moreover, many parts in the car are plastic products, which are glued together, and these substances will change after being exposed to the sun, thus releasing substances similar to formaldehyde. The more time you spend in the sun, the more these substances are released, which can be harmful to your body.

In addition, car seat leather can also be affected when exposed to sunlight.

Many car owners are also aware of it, so we can often see that some cars in the parking lot will be covered with a layer of clothing, and even if they are not covered, the windshield will be covered with a sunshade. Sometimes it is not necessary to avoid parking outside, which can not only prevent dust, rain and bird droppings, but also effectively prevent the car from direct sunlight. In fact, you can also make glazing, coating or reflective heat insulation film windows for the car, which can also effectively prevent the damage of high temperature and ultraviolet rays to the car.

When washing your car in the summer, never wash it in the sun, and don't wash it too often. Do not wash the car in the sun, otherwise it will damage the original car paint.

Be sure to pay attention to the cleaning time, do not expose it to the sun after cleaning, clean all the stains on the car, and do not wash the car after exposure.

Don't wash it on a rainy day, don't wash it in the sun, pay attention to the way you wash your car, and the tools you use to wash your car. I cannot wash it.

Because if you wash the car directly, it will cause great damage to the car, and you can't wash the car directly.

In the hot summer, when the car has been exposed to the sun for a period of time, many car owners will choose to wash the car at this time in order to cool down the car.

Because this is to prevent the end paint from rolling up after thermal expansion and contraction.

Because it is already very hot after exposure to the sun, if you wash the car, it may make it easy to peel.

Because if you wash the car directly, it will damage the paint of the car, which will affect the appearance of the car.

The temperature of the car itself is very high after exposure to the sun, so you can't wash it casually.

Because washing the car after exposure will cause great damage to the paint.

If you wash the car directly with cold water, then the skin temperature is very high, and the paint will be peeled directly.

It may reduce the hardness of the surface of the car, which can easily cause failure.

The main thing is that it is very harmful to clean the car at this time.

Car, don't wash too often. Because car washing, it does cause damage to the car paint. This damage, which may not be visible to the naked eye, can reduce the performance of the paint and affect the residual value of the car in the long run.

First, don't go to an automatic car wash machine to wash your car. New cars, cars over 200,000, especially luxury cars, never use automatic car washers.

In addition to the high-pressure water gun, the automatic car washing machine also has a high-speed rotating "mop" made of rubber to throw it on the car. This rapid friction with a certain force with the paint will speed up the peeling off of the protective wax that the new car paint wears at the factory. Of course, if the car has been around for a long time and has entered the category of broken cars, then it is not impossible to use an automatic car washing machine.

Second, use a high-pressure water gun to rinse the car in the car wash, if there is no sediment on the car, it is not a big problem. However, if there is mud and sand adhering to the surface of the car paint, try not to wash it with a water gun.

The pressure of the water stream pushes the sediment particles against the paint surface, which then moves rapidly, leaving marks on the surface of the varnish that cannot be seen or seen closely. In the same way, if the surface of the car is very dirty, if it is not washed with water, do not rush to wipe it with a rag, because some small sand particles are still left on the paint surface, which will move with the rag, thus straining the varnish.

Third, special attention should be paid to the car wash liquid used in car washes in car washes.

When washing cars in regular stores, you should choose a professional car wash liquid with a neutral pH, and add a certain amount of water wax to protect the car paint. Non-special car washing liquids, such as laundry detergent, have an alkaline pH and can cause damage to car paint!

Fourth, in hot weather, don't go to the car wash suddenly.

The paint surface is hot and cold, which will reduce the performance of the paint. In addition, the water droplets that remain on the paint surface after washing the car will form a convex lens that gathers sunlight and burns the car paint.

Fifth, the fabric towels and sponges used to scrub the car body have accumulated some dust particles in their pores after long-term use, and the use of these items to continuously wipe the body will inevitably leave traces on the surface of the varnish.

Therefore, the damage to the varnish when washing the car is self-evident. These injuries are usually ignored and can become apparent over time. When the varnish is damaged, the varnish suffers. The performance of the varnish will deteriorate, and the base coat will be more eroded by ultraviolet rays, rain, bird droppings, etc.

Frequent car washes can cause damage to the car paint. The following is an introduction to the damage to the car caused by frequent car washing: 1. Wound paint:

It will reduce the performance of the paint finish, and in the long run, it will affect the residual value of the car. The frequency of car washing should not be too high, try to wash the car at home, not only save money, but also try to avoid some damage to the car paint. When washing a car, the damage to the varnish is self-evident, and these damages are usually ignored and will be obvious over time.

There are a lot of chemicals in the cleaner that washes the car, and everyone should know the dangers of these chemicals, and some of them may even be corrosive.
