What should I do if my windows fog up while driving?

Cold air defogging. If you want to say that the most fundamental cause of window fogging, that is, the temperature difference between the inside and outside of the car is too large, and the outside is cold and the inside is warm, so it causes the windows to fog up. Therefore, if you turn on the cold air to remove the fog, you can quickly dry the water vapor on the windshield.

Therefore, it is ideal to urgently defog and blow with cold air while driving. But the effect is only temporary. After a while, you'll notice another layer of fog on your car windows.

And if you turn on the cold air in the car to remove the fog, it is really too cold, and the passengers in the car will not be able to stand it if they can't blow it.

Warm air defogging, using warm air defogging, the fog on the car glass will get heavier and heavier at the beginning, but after a while the fog will be dried by the warm air. And because the water vapor is gone, there will be no fog in the windows for a long time, and the interior of the car will be much warmer. This method is recommended for everyone to use before driving on the road, which can not only ensure safety, but also has a very good effect.

Open the window or defogger, if it is not particularly cold, you can also open the sunroof (window) of the car while driving, so that the temperature in the car is the same, so that there will be no fogging again. In addition, you can also mix the dish soap with some water, spray it evenly on the glass, and then wipe it clean with a dry rag, which can also remove the fog for a long time and will not leave traces.

There is only one way for several people to deal with fogging up the front windshield: turn on the air conditioner and blow it into the glass. But turning on the air conditioner on a cold day and getting cold yourself is not a long-term solution.

According to a technician with many years of experience in auto repair, the reason for the fogging of the car window is "internal heat and external cold". The temperature difference between the inside and outside of the car is 10 to 20 degrees Celsius, and the hot air exhaled by the occupants of the car condenses when it hits the cold glass.

Defog the windows so they are clean, fresh and do not obstruct your view. There is a front window defogging button on the car, and there is also a rear window defogging button.

When the windows fog up while driving, just turn on the warm air and blow it!

This is a good solution, as long as you open the window less, divide or turn on the air conditioner to blow the glass.

When driving on a rainy day, the windows are prone to fogging? The old driver teaches you a few tricks to solve it easily.

When the windows are fogged, you can use the air conditioner in the car to blow the glass to remove the fog.

The most economical way to remove fog is to blow it with hot air. The specific operation steps are: turn on the car air conditioner, adjust to the hot air position, and then start the external circulation, align the air outlet with the front windshield and blow the hot air directly, so that the outside air enters the car.

Under normal circumstances, the fog on the front windshield will dissipate in about 5 minutes.

You can also turn on the rear tilt mode of the sunroof, so that the fog can be cleared through the negative pressure principle of the sunroof, and at the same time, the air in the car can be circulated, and the temperature in the car will not be reduced too much.

There are the following solutions to fogging outside the car window:

1. Open the window and remove fog: adjust the button of the car glass to leave a gap in the window to reduce the temperature difference and avoid the fog of the car. In this way, the air inside and outside the car forms a convection, the temperature difference decreases, and the fog will slowly disappear;

The limitations of opening windows to remove fog are very obvious, if the fog in the car is large, or it is rain and snow weather, or driving on the highway, it is not suitable to open the window to remove fog, and opening the window will also reduce the temperature in the car;

2. You can use a clean rag to wipe the fog on the car window;

3. Air conditioning defogging: you can use the vehicle air conditioning system to defog, at present, basically all cars on the market have air conditioning outlets under the front windshield, just select the air conditioning to the corresponding gear;

In winter, the temperature difference between the inside and outside of the car is too large, and it is cold outside and warm inside, causing the windows to fog up. At this time, you can turn on the AC refrigeration switch in the car to let the cold air blow on the front windshield, and the fog will disappear soon;

4. Detergent blending method is sprayed on the outside of the car window to defog: use soap and dish soap mixed with water to spray on the glass, and form a layer of oil film on the surface of the glass to achieve the effect of no fogging. However, this oil film will cause the front windshield to form a dazzling effect at night, affecting driving safety;

5. Defogging with wipers: The fog outside the window is generally caused by rainwater condensation, and it is okay to scrape with a wiper, but if it is a frost in winter, it should be wiped with water, not with a wiper to avoid damaging the wiper;

6. Use defogging agent: spray the defogging agent on the inner surface of the automobile glass and wipe it clean, which can also form a protective film while removing the glass dirt.

In summer, there is no need to rush to fog the windows of the car, turn on the air conditioner to remove the fog in minutes.

In winter, due to the large temperature difference between the inside and outside of the car, many friends will encounter fogging of the car window, especially in rainy and snowy days. Don't ignore fogging of the windows, which can affect the driver's vision and pose a safety hazard to the vehicle. So, what to do about fogging up the car windows?

Here are a few tips for defogging.

If you find that the windows of your car are fogging, don't panic, you can open the windows on both sides of the vehicle, and the width of a fist will do. This causes convection of the air in the car, blowing the moisture away, and the fog quickly dissipates.

Turn on the fan and refrigeration switch in the car, and when the cold air blows onto the glass, the fog will quickly dissipate. This is because the cold air blows onto the glass, preventing the water vapor from condensing on the glass, and the defogging effect is obtained. However, this method can make the occupants feel cold in the winter, so you might want to give it a try.

You can also receive the effect of defogging with hot air! However, one thing to remind everyone is that if the glass has fogged up while driving, turning on the hot air switch will make the fog on the glass heavier and heavier. Therefore, it is recommended that riders do not try to blow the glass with hot air while driving, and it is best to blow the glass with hot air until it is dry before driving.

After the hot air dries the moisture in the car, the fog on the glass will disappear and it will only take a few minutes. One thing to note is that the rear and side glass temperatures rise slowly, so it takes a long time to remove all the fog.

Preventive methods such as spraying defoggers are used. Spray a little defogging agent on the car glass, and then wipe it clean, you can remove the dirt and stains on the glass. While polishing the glass, a thin layer of transparent protective film is formed on the glass.

It can effectively prevent the formation of fog caused by water vapor condensation on the glass, especially suitable for cold winters.

In summer, there is no need to rush to fog the windows of the car, turn on the air conditioner to remove the fog in minutes.

The principle of fogging up the windows is "hot inside and cold outside". The temperature difference between the inside and outside of the car is 120 degrees Celsius, and the carbon dioxide exhaled by the occupants of the car will condense into water vapor when it encounters cold glass, which will condense on the windows. Therefore, defogging is essential.

The following methods are available to solve the problem:

1. Open the window for convection, and when the fog is not very large, you can open a slit in the windows on both sides.

2. The air outside the car drives convection, the temperature difference is reduced, and the fog disappears.

3. Open the front windshield defogging button on the center console panel and adjust the alignment of each air outlet with the front windshield.

4. After the fog disappears, you can turn off the AC button of the air conditioner, continue to adjust the air volume a little smaller, and adjust the hot air to blow on the glass.

5. Spray the defogging agent evenly on a soft cloth, and then wipe the front windshield with a soft cloth, or spray it directly on the glass.
