Can I wash my car before getting on the highway, and can I wash my car immediately after running at

If there is no need to wash the car before the highway, whether the car needs to be washed depends on whether the car is dirty or not.

Car washing is not simply a hard work, but also pay attention to the method, you should pay attention to whether you go to the car wash or do it yourself, you must be in the car engine.

Wash the hood after it has cooled down thoroughly, especially in summer, and do not wash the car in strong sunlight, as this will cause the car engine to age prematurely.

It should be noted that different stains should be cleaned with different cleaning methods and different rags, such as cleaning the body of the car should be sprayed with dispersed water flow, do not wash with high-pressure water flow, excessive water pressure will damage the body paint. If there is hard dust and mud on the body, soak it with water first, and then wash it off with water.

Hello car owner, there is no need to wash the car before running at high speed, whether you need to wash the car depends on whether your car is dirty or not, and there is no dirty car can not be on the highway, and there will be a lot of mosquitoes on the front bumper of the high-speed car, it is recommended to clean it after running at high speed.

There is no need to wash the car during the high-speed time of the vehicle, there is no such requirement, but before the high-speed, you should check whether the tire pressure of the vehicle is normal, and whether there is a lack of antifreeze in the water tank.

Whether or not the vehicle needs to be washed before going on the highway depends on your own personal preference, and it doesn't matter if you don't wash the car, but you must make sure that the overall appearance of the vehicle is relatively clean.

This is not required, if the vehicle is dirty, it is still necessary to wash the car in time, and clean glass is also more conducive to driving safety.

It is not recommended to wash the car before getting on the highway.

On the high speed, the front face and front windshield of the car will hit a lot of small insects, a high speed down, countless insects, corpses.

It is recommended to wash the car after getting off the highway.

There is no car wash before getting on the highway! If the car feels dirty, wash it. It doesn't matter what kind of high-speed and low-speed it is. However, it is necessary to check the tires before hitting the highway.

Hello this rider, this is not necessary, before getting on the highway, if you want to run a long distance, it is recommended that you check your car, such as tire pressure, tires or something.

There is no such requirement. Whether to wash the car or not mainly depends on whether the car is dirty or not, and if it is dirty, wash it.

Generally, after running at high speeds, the engine and other systems can be washed after 15 to 20 minutes after getting off the highway. After running at high speed, the car, whether it is the brakes or the engine, is in the stage of heat dissipation. If you wash the car immediately and wash the brake disc with cool water, it will cause the brake disc to deform at least and cause the braking system to fail at worst, affecting driving safety.

After the car runs at high speed, do not wash the car immediately, wait for the temperature of the body to drop for a period of time, and then wash it, so as to have a correct maintenance of the car.

Because the speed of the car is very fast on the highway, the engine power is too high, when just getting off the highway, the engine temperature is high, coupled with the car's braking system, due to frequent work, resulting in huge heat, if the car is washed at this time, it is likely to cause the car steering wheel to shake violently, and even lead to the failure of the car's braking system.

In addition, due to the violent friction with the air and the increase in temperature during high-speed driving, if the surface of the car is washed with cold water, it is likely to cause the paint on the surface of the car to burst. In addition, if the car tires are washed with cold water after a long time of high-speed operation, it is likely to accelerate the aging of the car tires, which will aggravate the change of the tire pressure imbalance of the car, which may lead to unstable driving and even traffic accidents when the car is driven again.

Precautions. 1. Don't wash the car before the engine has cooled down completely, which will cause the engine to age prematurely.

2. Do not wash the car under the scorching sun, it will leave dry water beads on the body.

3. Do not wash the car in very cold weather, otherwise the water will freeze and cause the paint coating film to rupture.

4. Do not wash with water other than soft water, as it will damage the paint. If you use hard water, it will leave marks and a film after drying.

5. Do not wash the body with high-pressure water, it will damage the body paint. If there is hard dirt on the body, soak it with water and then rinse it with water.

6. Do not add detergent indiscriminately, do not use laundry detergent, detergent powder and inferior soap when cleaning, which may wash off the grease in the paint surface and accelerate the aging of the paint surface. Don't use stain removers, there may be very corrosive stains on the body, such as asphalt, oil stains, bird and insect droppings, etc., these stains are difficult to clean, and must be done in the right way.

7. Do not wipe indiscriminately, after rinsing with water, if you want to wipe, the cloth should use a soft cloth or a soft and clean sponge. When wiping, you should gently wipe from top to bottom in the direction of the water flow.

8. Do not use hard cleaning tools to remove dirt, such as plastic brushes and blades to scrape stains, which will easily damage the paint surface.

9. Do not touch the surface of the car body with dirty hands stained with oil, or put oily tools or wiping cloths containing organic solvents on the body, which will easily leave marks on the paint surface or make the paint surface fade prematurely.

The recommendation is not to.

First of all, because the speed of the car is very fast on the highway, the corresponding engine power is too high, so when you just get off the highway, the temperature of the car engine is very high, and at the same time, the braking system on the car, because of the frequent work, will also produce huge heat.

At this time, if you suddenly use a large amount of water to wash the car wheel, it is likely to cause the steering wheel of the car to shake violently, and even cause the car's braking system to fail, which is unimaginable.

Secondly, many car owners know that the cost of car paint is relatively expensive, because when driving at high speed, the violent friction with the air will still increase the temperature, if you immediately wash the surface of the car with cold water at this time, it is likely to cause the car surface paint to burst, which seriously affects the appearance.

Even after forcibly cleaning with water, the surface of the car will also have many markings due to uneven temperature, which will outweigh the losses.

Finally, after a long time of high-speed operation, if the car tires suddenly encounter cold water washing, it is likely to accelerate the aging of the car tires, and at the same time, because after the high speed, the tire pressure of the car has been affected to a certain extent, if the car is washed immediately, it will exacerbate the change of the unbalanced tire pressure of the car, which may lead to the car driving again, the driving is not stable, and even traffic accidents occur.

Therefore, after the car runs at high speed, do not go to the car wash immediately, the best way is to wait for the temperature of the body to drop for a period of time, and then go to the corresponding 4S shop for cleaning, so as to be able to maintain the car correctly.

It is best not to wash the car immediately, because after a long time at high speed, both the brakes and the engine are in a very hot state. It's like a person's heart suddenly startled by cold water. The engine cover and brake discs will have an impact on the vehicle when they encounter water, thermal expansion and contraction.

Hello, it's better not to wash, because after running at high speeds, the car is in the stage of heat dissipation, whether it is the brakes or the engine. At this time, washing the car and washing the brake disc with cool water will cause the steering wheel to shake, and the brake system will fail at worst, affecting driving safety. The car temperature is too high to cool for a while, and it comes down to rinse!

Safety first.

It's best to stop for a while and wait for all aspects of the engine to dissipate heat before washing.

If your car has just finished running at high speed, don't rush to wash the car, otherwise you will regret it.

The car table can be washed when the engine temperature drops, but in the summer, I am afraid that the outside temperature will be high, and suddenly the car will be washed in cold water, which is not good for the machine and the glass.

If the car temperature is too high, it will cool down for a while, and then it will be washed down! Safety first.

If your car has just finished running at high speed, don't rush to wash the car, otherwise you will regret it.

You can wash your car 15 to 20 minutes after getting off the highway. Some drivers rush to wash their cars just after running the highway, and it's nothing in winter. If it is in the summer, if the road conditions are not good and the brakes are used frequently at high speeds, the brake discs will heat up severely.

At this time, if the car is washed immediately, it will cause great damage to our brake discs. In addition, when running at high speed in summer, the car paint is exposed to the sun for a long time, and the car paint is not very good when washing the car at this time.

Just off the highway can not wash the car immediately. 1. Wait 15 to 20 minutes to talk about the engine to cool down before going to wash the car. The car has been running at high speed for a long time, then its various functions must be running at high speed, just like the engine is burned in it through fuel, so it can produce power After running at high speed for a period of time, its engine will definitely be very hot.

2. Not only the engine, such as the transmission, but also some other places where the activities are more flexible, as long as they are cleaned with cold water, they will cool down quickly. will have a bad effect on their performance. Especially when the car is repaired and you start it again, you will find that the car is less flexible, as if the engine is about to start for a long time as if it is frozen.

Its stability is also affected at the start, which is the consequence of the hot and cold conflict. In addition to the hazards of washing the car directly after the high-speed car is running at high speed, there is also the fact that washing the car when it rains is actually harmful. Chagao.

Summary. You can't wash your car immediately after running at high speed, and you can wash your car only after the car has cooled down. After running at the high speed for a long time, just getting off the high speed, both the brakes and the engine are in a very hot state.

The engine cover and brake disc will have an impact on the vehicle when exposed to hydrothermal expansion and contraction, causing the steering wheel to shake at least and the braking system to fail.

You can't wash your car immediately after running at high speed, and you can wash your car only after the car has cooled down. After running at high speed for a long time, just staring at the high speed at the age of pure age, whether it is the brake or the engine, it is in a very hot state. The engine cover and brake disc will have an impact on the vehicle when it encounters hydrothermal expansion and contraction, causing the steering wheel to shake at least and the braking system to fail.

I washed it once today, so it's fine.

I got off the highway and parked on the side of the road for about 15 minutes, but it didn't turn off, and I ran for about 10 minutes in the city to wash the car.

Are you there. If there is no obvious fault at the moment, there is no problem.

Today we will introduce the knowledge about automobiles. In the daily use of cars, there are often a variety of problems encountered. Do you have a friend who washes his car after a high-speed drive?

The following is a brief introduction to facilitate you to have a further understanding of this issue. So, I won't say too much, let's understand it together.

Driving on the highway can wash the car.

There are no laws or regulations regarding when and when a partner wants to wash a car.

However, it must be noted that after driving on the highway for a long time, you can't wash your car right away just after getting off the highway. The car cannot be washed until it has cooled down. Basically, the rotational speed is maintained at about 2,000 rpm and the operation can be carried out for more than 15 minutes.

If you drive on the highway for a long time and just get off the highway, whether it is the brakes or the engine, it is almost always hot. The hood and brake discs encounter water, thermal expansion, cooling, and are associated with the car. Lightness will affect the shaking of the steering wheel, vibration, weight, and the failure of the braking system, which is related to safe driving.

Comes with car washing taboo:

1. If the engine is not completely cooled, you hate car washing. This will make the engine deteriorate sooner.

2. It is strictly forbidden to wash the car under the scorching sun. This will leave traces of dry water beads on the body.

3. It is strictly forbidden to wash the car in very cold weather. When water freezes, the coating film of the paint breaks.

4. Avoid rinsing with clean water other than soft water, including molded hot water, alkaline water, and water with high hardness. These macro-terrestrial materials can damage the paint. After washing and drying with hard water, it leaves marks and films on the surface of the body.
