How to solve the fogging of the front glass of the car, and what to do if the fog outside the front

Air conditioner defogging

This is the easiest way, just turn on the front window defogging mode, then turn the wind speed to the maximum, turn on the AC switch, and then turn the temperature to the lowest, and the fog on the glass will disappear in a while. In addition, the rear windshield and exterior mirrors of some models are equipped with electric heating, which can be used to eliminate fogging in about a minute after the switch is turned on. In addition, many vehicles now have a one-key defogging function, which can be turned on when fogging, which is convenient and fast.

Air convection: This method is suitable for very few situations, after opening the window, you can increase air convection, reduce the temperature difference between the inside and outside of the car, and weaken the fog formation conditions, this method seems to be very economical, but the situation is really too little, if it is raining outside, it is impossible to open the window, and the wind blowing in is also quite limited.

1. Spraying anti-fogging agent and other preventive methods: first wet the entire windshield with the anti-fogging agent, and wipe the anti-fogging agent with a clean and soft towel after a short wait. In the process of wiping, the anti-fogging agent will form a protective film, so it is difficult for the air to form a water mist on this film, and the better thing is that the anti-fog film is valid for 10-15 days, which is very easy to use in the season of frequent fogging.

2. Air conditioning and refrigeration method: The windshield fogging is usually due to the large temperature difference between the inside and outside, and there is more moisture in the car. At this time, you can turn on the air conditioner to blow cold air on the front windshield, and use the air conditioner's dehumidification function to remove the fog vapor on the front windshield slightly.

However, if the humidity is too high and the effect of air conditioning is not obvious, you can open the windows a little to quickly reduce the humidity in the cab.

3. Use air conditioning heating system to defog: the cause of fogging of car windows is usually caused by two conditions, one is that the air humidity in the car is too high, and the other is that the temperature gap between the inside and outside of the glass in the car is relatively large, and the defogging is to solve these two problems. The hot air can not only dry part of the air in the car and reduce moisture, but also reduce the temperature difference between the inside and outside of the window.

However, the temperature of the glass at the back and sides rises slowly, so it takes a long time to remove all the fog.

Pacific Automobile Network] The front glass of the car can be fogged with air conditioning, this method is the most labor-saving and fast, find the front window defogging mode, and 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 be gone after a while.

If it is winter, you can take the air conditioner hot air defogging, if the car has just started, do not start the air conditioner for the time being, wait until the engine is preheated for a few minutes, after the water temperature rises, then start heating, adjust the air volume to the maximum, and then also turn on the front window defogging mode, and the fog will disappear in a few minutes. The more economical method is to use the ventilation fan to blow the hot air, this method is to open the ventilation fan, adjust to the external circulation, align the air outlet with the front windshield, and blow directly with the hot air.

The operation of automatic air conditioner defogging is very easy, turn on the automatic air conditioner, adjust the mode switch to the defogging stop, and then the air conditioner will automatically convert to external circulation. If it is a manual air conditioner, first of all, the wind direction switch should be adjusted to the defogging block, and the external circulation should be started to let fresh air blow in to achieve the effect of removing lead mist.

In addition, you can also use a special defogger to solve the problem, but you need to prepare for it in advance. There is also a common use of sleepy manual wiping, although the effect was obvious at that time, but if it is operated during driving, it is easy to be dangerous, it is recommended that everyone still focus on safety, and must not wipe manually while driving.

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.
