What should I do if the front glass of my car fogs up on a rainy day?

In the rainy season, the fog in the front windshield is caused by the inconsistent temperature inside and outside the car. If it is too hot, you need to open the windows to make the temperature match the temperature outside the car, and the windshield fog will disappear.

In winter, the glass fogs, generally need to wait for the warm air to come up before driving, and the fog will disappear with the warm air wind, but remember that the inner circulation button must be turned off when the warm air is turned on in winter, because once there are too many people in the inner circulation, it may absorb the breath of the people in the car and produce fog.

There is also a possibility that the windshield can also produce fog, that is, the small water tank on the car leaks, and the fog generated by this fault can only be solved by replacing the small water tank.

Car glass is easy to fog, teach everyone a good way.

The development of modern sedan appearance is closely related to the development of glass technology. As early as more than 40 years ago, the front windshield of a sedan has adopted a single-piece curved windshield, and gradually abandoned the flat windshield.

What should I do if the front glass of my car fogs up on a rainy day? Come in and learn, don't let your vision cover your eyes.

1.You can turn on the air conditioner to hot air before the car starts, and blow the front windshield directly for 3 minutes, which can fundamentally avoid fogging the glass;

2. Turn on the cold air of the car air conditioner and turn the air outlet to the windshield in front of the car, so that the glass fogging can be quickly removed;

3. Turn on the dehumidification mode of the air conditioner to achieve a relatively fast defogging effect;

4. The owner can turn on the defogging function of the air conditioner, and the fog will dissipate quickly.

The main reason for the fogging of car window glass is that the temperature difference between the inside and outside of the glass is too large, and the other is that there is too much moisture. In winter, the warm air conditioner is turned on. In addition, when the weather is wet on a rainy day, both factors are satisfied, and it is easy to fog up.

If you don't want the glass to fog up, it's best to keep the temperature inside and outside the car consistent.

Car glass is easy to fog, teach everyone a good way.

Workaround:

1. Spray anti-fogging agent for car windows.

2. Adjust the air outlet position of the air conditioner to blow the front windshield glass, so that it will not fog up.

3. Open the window appropriately to make the air circulation inside and outside the car consistent, and avoid fogging on the surface inside the windshield.

But there is no way to defog permanently. Window fogging is caused by a temperature difference between the sides of the window when the temperature is below freezing.

Ways to avoid fogging up your car windows:

Method 1: Spraying anti-fogging agents and other preventive methods. Spray a little defogging agent on the car glass window, and then wipe it clean to remove the dirt and stains on the glass window.

While polishing the glass, a thin layer of transparent protective film is formed on the glass, which can effectively prevent the condensation of water vapor on the glass and form a fog layer, which is especially suitable for cold winters.

Alternatives to anti-fogging agents and dish soap, soap, glycerin, alcohol or salt water are allowed to dry before wiping off excess fibers with suede or a soft, dry cloth that will keep the glass from fogging up for a few days.

Method 2: Air conditioning and refrigeration method. The air conditioner refrigeration and dehumidification function is used to reduce the air humidity to remove fog. When in summer, especially after many people enter the car, the air conditioner is not turned on in time, and the humidity of the air exhaled by people is large, and soon the front windshield will fog up.

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. Of course, it can also be used in conjunction with air conditioners, and the effect will be faster.

Method 3: Air conditioning and heating method. Fogging is removed by reducing the temperature difference. In winter, the warm air is used to blow hot air on the glass, which quickly increases the temperature of the front glass and reduces the temperature difference between the inner and outer surfaces of the window glass, which can prevent the fog vapor of the front windshield from being too heavy in time, but there is a point that the temperature of the rear and side glass rises slowly, so it takes a long time to remove all the fog.

Note: Whether it is an automatic or manual air conditioner, the air conditioner is turned on, which is conducive to dehumidification; Do not control the temperature of the air conditioner in the coldest position, otherwise the outside of the windshield will be easy to fog up after long-term defrosting.

Lower the front window, open the maximum cold air defogging of the external circulation, and open the front windshield hot air after the engine temperature is enough

The cause of windshield fogging is caused by a large temperature difference between indoor and outdoor temperatures. If the driving environment is more complicated during the driving process, you can use the cold air to do it, which has the advantage of quickly removing the fog on the windshield and avoiding the inability to see the road due to fogging. However, because the indoor temperature needs to be high in winter, after removing the fog, the temperature should be adjusted to the warm air position several times to prevent the fog from reappearing.

If you are in the parking phase or just hot car stage, you can directly use the way of blowing warm air, although the fog removal time is relatively slow, but the warm air should be turned on all the time, if necessary, turn on the front windshield defrost function. This prevents the fog from re-generating and meets the temperature needs of the indoor driver.

1. Rational use of air conditioning system.

2. Use special anti-fog products.

3. Open the window to convection of hot and cold air.

4. Wipe with dish soap and dry cloth.

5. Defogging of the heating wire of the rear windshield.

Use air conditioning or warm air to defrost the front window, and the fog from the front windshield and the left and right front door glass can be removed. Pay attention to where to defrost with the front windshield.

Fogging is the reason why the internal and external temperatures are different, turn on the fan, turn on the warm air in winter, open the external circulation in summer, and adjust the air outlet before the window is OK, and it will be done in 5 seconds.

1.Buy a special car glass defogging spray, ** is available. Pros: Simple. Disadvantages: Higher fees.

2.Apply the same detergent used for car washing (do not dilute) directly to the inside of the car glass and polish it when it is completely dry. The effect is obvious.

Pros: Cheap, negligible fees. Cons:

The taste is unpleasant. It's going to take a long time for that thing to dry. The polishing process is a cup.

When washing a car, scrubbing the inside of the window is also a cup.

3.Turn on the air conditioner, but does it need to be said? If that's all there is to it, do you still ask?

Turn on the outer circulation, and turn on the air conditioner to blow the front gear, and there will be no problem.

1. Air conditioning refrigeration and defogging.

There are two main causes of fogging of car window glass: low temperature and high humidity in the air. Air conditioning refrigeration can be used to remove fog from the front windshield, but if the air conditioner in the car is too humid, then the effect will not be too obvious, and the windows can be opened slightly to quickly reduce the humidity in the car.

2. Open windows for convection and defogging.

If the fog is not large, you can open a gap between the windows on both sides so that the air in the car can be convection, and the temperature inside the car will slowly approach the temperature outside the car, and the fog will dissipate. The advantage is that it can achieve the effect of turning on the air conditioner without increasing fuel consumption, such as in the cold winter and rain, it is recommended to take intermittent opening and closing of the window. This method is not suitable when fogging is severe.

3. Anti-fogging agent.

The use of glass anti-fogging agents can form a transparent hydrophobic ionic membrane on the surface of the glass to prevent the condensation of water beads and mist."

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.

After the rain, glass fog can be used: air conditioning refrigeration defogging, window opening convection defogging, anti-fogging agent, anti-fog towel, detergent anti-fogging.

1. Air conditioning refrigeration and defogging.

There are two main causes of window glass fogging: low temperature and high air humidity. You can use air conditioning refrigeration to remove the fog from the front windshield, but if the humidity of the air conditioner in the car is too high, the effect will not be too obvious, and you can open the window slightly to quickly reduce the humidity in the car.

2. Open windows for convection and defogging.

Open the window to convection the hot and cold air, if the fog is not big, you can open the gap between the two sides of the window, the air inside the car is convection, the slow temperature of the car is close to the temperature outside the car, and the fog will disperse. Its advantage is that it can achieve the effect of turning on the air conditioner without increasing fuel consumption, such as in winter and rainy days, it is recommended to take intermittent window opening. This method is not applicable when fogging is severe.

3. Anti-fogging agent.

The use of glass anti-fogging agents can form a transparent hydrophobic ionic membrane on the surface of the glass, preventing water droplets from condensing and fogging.

4. Anti-fog towel.

When fogging, wipe it with this anti-fog towel, and it will not fog again, and the effect of the anti-fog towel is exactly the same as the medicine.

5. Detergent anti-fogging.

Mix it with detergent. The ratio of washing spirit to water is about 1:10, and then apply it to the inside of the windshield with an absorbent cotton wool or a clean soft cloth, or you can use shampoo or body soap at home.

Causes of fogging of car glass on rainy days:

1. It is a rainy day, the temperature difference outside the car and the interior of the car is relatively large, even if it is a rainy day in summer, there will be a temperature difference in the car and the outside of the car, the temperature outside the car is very low, the temperature in the car is very high, then the temperature on the window glass will be reduced, and the moisture in the car will condense into water mist in the cold window.

2. On rainy days, the moisture in the air is relatively large. When the door is closed, water from your feet is carried into the car, and the moisture inside the car increases, so it is easier to form fog.
