How to solve the fogging of the car glass, what to do if the car glass is fogging?

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.

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.

Auto glass fogging is usually more common in rainy days, cooling days and other weather environments, we can prevent glass fogging through air conditioning defogging, glass defogging, homemade defogging, such as preparing dish soap and other methods, each method has its own advantages and disadvantages.

1. Choose glass defogging agent, which is the most reassuring for prevention;

Glass defogging agent** ranges from tens of yuan to hundreds of yuan, various brands are dazzling, in fact, their composition is not much different, you only need to spray it evenly on the surface of the glass when using, and then wipe it clean with a dry towel. The defogging agent will retain a certain protective film on the surface of the glass, change the surface tension of water molecules, and make the fog beads condense into large water droplets, so as not to block the view.

Second, choose homemade defogger, ** the most cost-effective;

If you are worried about buying a low-quality product, we can try to make your own defogger, the most widely used formula is to mix dish soap and water, mix it up in a 1:6 ratio, put it in a spray bottle, spray it evenly on the glass surface, and then wipe it clean with a dry towel. The blended dish soap does have the same effect as the defogger, but the only drawback is that it is slightly less durable.

Third, the method of air conditioning defogging should be accurate.

For manual air conditioning, turn on the front window defogging mode, then adjust the wind speed to the maximum, turn on the A C switch, and then adjust the temperature to the lowest, and the fog on the glass will disappear after a while. In the case of automatic air conditioning, you generally only need to press the one-button defrost button, and after pressing it, the air volume will automatically turn on to the maximum and open the external circulation, which is both practical and convenient.

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 seep and disperse. 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 of the car feel cold during the winter months, so you might as well 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. A little defogging agent is sprayed on the car glass, and then wiped, and 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.

Pacific Automobile Network] The solution to the fogging of automobile glass: 1. You can first wipe the fog on the window with a clean rag; 2. Adjust the car glass button to leave a slit in the window of the car, so as to facilitate the air convection inside and outside the car, reduce the temperature difference and avoid the fog of the car; 3. Start the car engine in neutral or parking gear first to warm up the car; 4. After the water temperature gauge comes up, turn on the car air conditioner, and at the same time open the window defogging button to dry the water mist on the window through hot air.

The fogging of glass at home is due to the temperature difference between indoor and outdoor, and the humid and cold air outside condenses when it comes into contact with the glass with higher temperature, forming fog and water droplets on the glass. To prevent the glass from fogging, you can often open the window to cool down to balance the temperature difference between indoor and outdoor, or you can take the window sealing treatment to avoid cold air entering.

Why does the glass at home fog up?

1. The temperature difference between inside and outside the home glass fogging is because in winter, there is a temperature difference between indoor and outdoor, when the window has a gap or no drainage hole, the outdoor moist and cold air will enter the home, and the condensation reaction occurs in contact with the glass with higher temperature, forming fog and water droplets on the glass.

2. Open the window to cool the glass at home The serious fogging can be dealt with by opening the window to cool down, because the water vapor on the window is caused by the temperature difference and humidity between indoor and outdoor, and the intermittent window ventilation can balance the indoor and outdoor temperature and humidity and reduce the generation of water vapor.

3. Window sealing treatment: If the glass fogging at home is serious, the method of window sealing treatment can be adopted. Window sealing treatment is to use cloth strips, tape and other tools to close all gaps in the windows of the home, which can effectively prevent low temperature airflow from entering the room, which is not only conducive to indoor insulation, but also can completely solve the problem of glass fogging and dripping.
