What to do if the outside of the car window keeps fogging, and how to solve the fogging outside the

Here's how to fog up the outside of the car window all the time:

Tools Raw materials: BYD, glass water, anti-fogging agent, soapy water.

1. Turn on the cold air of the car: Generally, the fog outside the window is caused by the large temperature difference between the inside and outside, at this time, we can turn on the cold air inside the car and blow the cold air on the glass outside the window, and the window glass will be very clear after a while. (This method is not suitable for winter, because it is too cold for people to stand it.)

>2. Turn on the warm air of the car: After the car starts, adjust the air conditioner of the car to the warm air shield and blow it against the glass. But it takes a long time to ensure that the temperature difference between the inside and outside is the same, so that the fog can disappear and the window glass can be clear.

3. Window anti-fogging agent: We can go to the Internet to buy some window anti-fogging agent, and then apply it to a towel, and then wipe the glass around the window, so as to avoid fogging the window, this method can last about a week.

4. Apply soapy water: This method has a low cost, but it is troublesome, we can wipe the glass inside and outside the window with a towel with soapy water, and when the soapy water is dry, it can have the effect of anti-fogging, and the validity period is about one week.

5. Window glass water: The last one is more affordable, we can buy some glass water, and then apply it to a towel, and then use it to wipe the car window, which can effectively protect the window from fogging, and the time is about a week.

The solution to the problem of fogging up outside the window all the time is as follows:1. The simpler way is to use the method of air conditioning and refrigeration, plus external circulation, to remove the fog from the front windshield. If the humidity effect of the air conditioner is not obvious, you can open the windows at the same time to remove the fog faster.

2. If the fog is not large, you can open the window a little, which can also make the temperature inside and outside the car close, and the fog can be removed.

3. The air conditioner warm air blowing on the windshield can also make the heating, drying the water molecules of the front windshield, and also has a good effect of removing fog.

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. 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.

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.

1. Open windows for convection

If we find that the fog inside the car is not large, we can open the windows on both sides, so that the air inside and outside the car will form a convection, the temperature difference will also decrease, and the fog will slowly disappear. The principle of this method is the same as turning on the air conditioner and cold air. The disadvantages of open window convection are very obvious, and it is not available in rainy and snowy weather, highways, and fog.

2. Cold air defogging

For most car owners, the use of air conditioning system to defog is the most common. Nowadays, almost all cars on the market have air conditioning outlets under the front windshield, and you only need to select the air conditioner to the corresponding gear to use the air conditioning to defog. Cold and warm air have their own advantages and disadvantages, if you are in a hurry to hit the road, you can use cold air for emergency.

In most cases, we recommend using a warm air.

3. Warm air defogging.

The cold air effect is straightforward, but there is one biggest drawback, after turning off the cold air, the fog will reappear. Therefore, we do not recommend using cold air defogging. The effect of blowing glass with hot air is better than using cold air.

However, due to the low water temperature when it is first started, it takes a while for the air conditioner to blow hot air, so the waiting time is long. When the hot air is blown, the fog inside the car will become larger, because the temperature difference between the inside and outside is also larger, and when the hot air dries the moisture in the car, the fog will disappear completely. Remember, wait for the fog to disappear completely before hitting the road.

4. Defogging agent.

The defogger is a product specially designed for this kind of water mist phenomenon, spraying the defogger on the inner surface of the glass, and wiping it clean, while removing the glass dirt, it can also form a protective film to prevent water vapor from condensing on the glass and forming a fog layer, and the spray wipe can prevent fogging for about 5-10 days. Another way is to mix the washing spirit with water at a ratio of about 1 10 and apply it to the inside of the window windshield and the mirror surface of the rearview mirror, which can also have the same effect, but can only prevent fogging in the short term.

5. Rear windshield heating.

Most cars basically have a "rear windshield electric heating" function, and the button position will be different, but the function is the same. Turn on the "Rear Windshield Heating" switch, and it only takes a minute or so for the fog from the rear windshield to disappear.

Wipe clean.

Defogger Defogger on the market ranges from tens of yuan to hundreds of yuan, and the ingredients are not much different, and the only difference may be durability. To use it, you only need to spray it evenly on the glass surface and wipe it clean with a dry towel.

If the wiper of the car is not clean, foggy or has abnormal noise, it will cause the driving vision to be affected, generally because of the rubber strip of the wiper There is a problem, which may be caused by long-term exposure to hardening or corrosion in rain and snow, so here there will be a wiper friction between the front windshield is not very uniform or there is a sealing system to produce a scraping area. In this case, it is recommended that you go directly to Jiajia ** or a certain treasure, a certain east to buy a pair of wipers that match the model of the car, come back or find a car wash brother to help install it, the effect is very obvious.

The solution to fogging outside the window windshield is as follows:

1. Open the window for convection, if the fog is not big, you can open a gap in the windows on both sides to let the air in the car be convection, and the fog will disperse when the temperature in the car is close to the temperature outside the car, but this is only suitable for the state of low-speed driving.

2. Reduce the wind speed to open the external circulation, and then adjust the air volume to the first gear of full glass blowing, but the effect of defogging will be slower, which is only suitable for the case of small fog.

3. The ratio of anti-fogging agent washing spirit and water is about 1:10, and it can be smeared on a glass with a cloth, which not only has a short defogging time and less cost, but also has no detergent to remove fog with the help of glass water.

4. When the fog is heavy, open the window convection or use the wipers does not work, adjust the temperature of the air conditioner to warm air, adjust the temperature, rotate the direction of the air conditioner to the full blowing glass, and soon the fog will disappear, and the effect is very obvious.

Precautions for driving in foggy weather

1. Reasonable use of lights: When driving in foggy days, the fog lights should be turned on. If the fog is very large, turn on the double flashing lights to avoid rear-end collisions and scraping accidents. The high beams cannot be turned on on foggy days.

2. Pay attention to the speed limit: When driving in foggy areas, turn on anti-glare low beams, width indicators and tail lights according to different visibility, and appropriately increase the driving distance to reduce the speed, and the speed shall not exceed 20 kilometers per hour.

3. Don't step on the brakes suddenly: Suddenly stepping on the brakes can easily cause the driver of the rear car to react to a rear-end accident, and if it is on the highway, it is more likely to cause a series of rear-end traffic accidents.

Hello dear, when the car is moving, the temperature difference between the inside of the window and the outside is the main cause of glass fogging socks, especially when the weather is cold, wet or foggy. There are several ways to solve window fogging:1

Use an on-board dehumidifier: Many cars are equipped with an on-board dehumidifier. Turning on the car dehumidifier removes moisture from the humid air inside the car, reducing the possibility of glass fogging.

2.Use a defogging switch: Most modern cars have a defogging switch that can be pressed when the window is fogged.

This function uses the air conditioning system in the car to minimize the temperature difference between the interior and exterior and remove fog. 3.Use a window heater to sell it

Some cars have windows equipped with heaters, which can be used to heat the surface of the glass to remove the fog when fog builds. 4.Open the window:

Boot windows allow moisture to be released from inside the car, reducing the likelihood of glass fogging.

1.Open the window to remove the fog: If the fog in the car is not large, you can open the windows on both sides to a small gap, so that the air inside and outside the car forms a convection, the temperature difference decreases, and the fog will slowly disappear.

However, 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.Air conditioning defogging: for most car owners, the use of air conditioning system defogging is the most common practice, 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 the outside is cold and the inside is warm, resulting in fogging of the car windows.

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; But this method has one of the biggest drawbacks, when the weather is cold, the people in the car will feel very cold, and after turning off the cold air, the fog may reappear; 3.Use a mist eliminator:

Spraying a defogger onto the inner surface of the car's glass and wiping it clean creates a protective film while removing dirt from the glass. At the same time, the owner can also use soap and dish soap mixed with water to spray on the glass, by forming 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;

1. You can use a clean rag to wipe the fog off the car window. Adjust the car glass button to leave a slit in the window to reduce the temperature difference and avoid car fogging. It can also be defogged by using the on-board air conditioning system, and can also be defogged by the dish soap blending method.

2. If it is foggy outside the window, it is generally made of rainwater condensation, and it is okay to scrape it with a wiper, but if it is a frost in winter, the stove is old, so you should wipe it with water, and do not use a wiper to scrape hard, so as not to damage the wiper.

3. If there is fogging in the window, you can open the window to ventilate and let the air circulate inside and outside, or turn on the air conditioner to blow the windshield in front of you, which can effectively deal with the fogging of the window in the car. And whether it is fogging the windows inside or outside the car, you can use dish soap poured on the towel to wipe the glass, and after a few minutes of foam disappearing, the fog on the window will be very effective.
