What should I do if winter is here and the windows are prone to fogging?

<> as the weather changes, we inevitably encounter a wide variety of problems while driving. Some issues are not important, but some are closely related to our driving safety, and when you get up and drive in a winter morning, a layer of fog appears on the car glass. Fogging up the windows can seriously affect our driving vision and cause safety hazards.

This is the biggest headache for car owners in winter. How to solve the problem of anti-fog driving in winter. Some drivers will choose to wipe it with a rag.

First of all, the first measure is the defogging spray. Spraying a layer of liquid film on the front glass before departure can effectively prevent frost and fogging; Spray on the road to quickly eliminate condensation of frost and fog. One spray can last 2-3 days.

If you notice that the vehicle is fogging again, you should stop and spray again. Similarly, dish soap can also be used. Soak the cloth with water first, then pour detergent and wipe it on the inside of the windshield, which can effectively prevent fog from forming for about 20 hours.

Secondly, the second measure is to blow the glass directly. As for the situation that the left and right glasses are sometimes foggy, you can adjust the direction of the left and right air conditioners to face the left and right glasses without affecting the rearview mirror.

Again, the third measure is to open the windows intermittently so that air can circulate and the rise of fog can be reduced. Since the air inside the car is not dispersed well, frost and fog can be produced when cold air outside the car is encountered. Roll down some windows appropriately to let the cold air from outside the car blow into the car to achieve convection of hot and cold air, which can reduce the temperature difference between inside and outside and eliminate frost and fog.

This method works well for a lot of people.

Finally, the fourth measure is to turn on the air conditioner first, wait for the frost and fog to dissipate, and then turn on the heating. Turning on the air conditioner can quickly reduce the temperature of the front windshield, so that frost and fog lose the condition of condensation. Turning on the warm air conditioner is to prevent the owner from feeling cold.

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 such a situation, you should choose to open the inner loop, so that the fog on the window can be removed.

You can wipe the glass with soapy water, dry the fog directly with a towel, open the windows to allow air to convection, or you can use a defogger.

First of all, wipe the glass first, then use detergent 1:6 with water, wipe both sides of the glass, and then turn on the air conditioner to dry the glass.

The treatment method of fogging the car window in winter is as follows: 1. You can open the window to let the cold wind outside blow in to reduce the temperature difference between the inside and outside of the car, which will help to remove the fog, but this method will make the people in the car feel cold and uncomfortable, and the effect is slow. It can also be dangerous if the vehicle balances the indoor and outdoor temperatures by simply opening the windows while driving.

2. Now there will be a button on the air conditioner in the car specifically for the defogging function of the front windshield, turn on this switch, the air conditioner will blow on the glass with a large air volume, quickly blow away the moisture, and also reduce the temperature difference of the glass. Nowadays, most of the fogging of the front windshield glass is done in this way. 3. Although the car is basically equipped with this defogging function, there will always be certain safety hazards when passively eliminating it after fogging, and some preventive measures can be taken.

Now there are special glass anti-fog products, spraying the anti-fogging agent on the glass, and then wiping it dry, can prevent the occurrence of fogging phenomenon and improve the safety of driving. The effect of anti-fogging agents can generally last for more than 1 month, and before winter really comes, you can use it in advance to avoid this problem.

The following are the specific methods for fogging the windows in winter: 1. Turn on the warm air to blow the front window. You can also use soapy water inside and outside the front window to smear (you can't use laundry detergent water, soapy water contains grease), and then use a wiper to scrape once or twice, the soapy water in the front window can be gently tried with a paper towel to semi-dry, after the soapy water is completely dry, the front window glass will not fog up, as long as you don't try, it can generally be maintained for about 1 week.

2. Install a rain shield: There are generally two kinds of rain shields, one is glued to the top of the rearview mirror, and the other is inserted in the gap between the rearview mirror and the frame. But there are drawbacks:

When the rain is not very heavy, the rain shield is still very effective, but when it is windy and rainy, the role of the rain shield will be weakened, but at least one third of the rearview mirror can be guaranteed. The method is to start the air conditioner first, adjust the temperature to warm air, and use the hot air of the air conditioner to dry the fog in the car. In this way, not only the front windshield, but also the surrounding windows are clear and transparent.

4. Wipe and wash the spirit on the mirror. This is a temporary method, which is to put some car wax on the mirror surface, or rub some washing spirit, soapy water, etc., which can maintain the effect for a day or two. However, light rain is still easy to adsorb on the mirror surface, and the effect is relatively better in heavy rain.

1. Wipe with a dry rag. To prepare a rag, this is the most economical type, and of course the effect is also very practical. Whether it's winter or summer, keep a clean rag in the car, and wipe it in time if you see a tendency to condense fog on the glass.

Be careful not to use a dry rag and try not to leave a watermark when wiping, so as not to affect the line of sight.

2. Open windows for convection. If you just notice that the fog in the car is not very serious, you can open a gap between the windows on both sides, so that the air inside and outside the car will form a convection, and the temperature difference will be reduced and some moisture will be brought out. It can not only ventilate, but also defog, and the car will not be filled with cold air at once.

3. Air conditioning hot air. It is also possible to use the air conditioner to heat and defog the windshield, as the continuous high temperature will dry the fog on the windshield, but this method may take a little longer and the fog on the glass may be worse at first, but after a period of time the fog will dissipate, which is more effective. However, there are also drawbacks, the temperature in the car is high, you may feel stuffy, and it is easy to get sleepy.

4. Automatic defogging of automobiles. The automatic defogging function is directly activated, and the air outlet under the front windshield can directly and effectively blow away the fog. However, not all cars have this function, and many ordinary family cars on the market do not have this function, so this method has certain limitations.

5. Anti-fog supplies. You can choose some anti-fog spray, spray it evenly on the window before driving, you can form a transparent protective film, prevent the moisture in the car from coming into contact with the window to form fog, and also keep the glass surface clean and tidy. Most sprays can last for many days at a time, and they are not very expensive, which is also a relatively convenient way.

However, there are many kinds of anti-fog products on the market, so it is recommended that you compare them and try to choose formal ways to buy.

6. Open windows for natural ventilation. The root cause of fogging in the car in winter is due to the large temperature difference between the inside and outside of the car, so you can choose to balance the temperature difference between the inside and outside of the car. Intermittently opening the windows or sunroof will reduce the temperature in the car, making it less likely to fog up.

But this has a little premise, you have to resist frost, and the temperature in winter is still relatively low. However, this method is still more recommended, because the warm air is often turned on in winter, and the temperature in the car is high, so it will make people easy to get sleepy, and opening the window to ventilate can effectively alleviate the problem of sleepiness during driving.

<> "Presumably all friends who drive have experienced fogging of car glass, which generally occurs in rainy days or cold autumn and winter seasons. As we all know, when there is fog on the glass, traffic accidents are very likely to occur due to obstruction of sight, which brings great hidden dangers to driving safety, and it will fog up again after wiping off the fog with a towel, and the glass can not be wiped at any time while driving. Is there any better way to remove the fog?

1.Use the air conditioner's defogging block for quick defogging. Cons: Fuel efficient!

2.Open the windows a small slit to allow air to circulate inside and outside the car. Disadvantages: You need to endure the cold.

3.Apply some glycerin, alcohol, salt water or even dish soap to the inside of the windshield to keep it foggy for a short time. Disadvantages: Short-term effective, one wipe is gone.

4.Manually wipe the fog. Disadvantages: Increased driving hazards. Automobile repair and maintenance net.

5.Nanotechnology's defogging and anti-fogging products, which can avoid fog condensation, are said to be valid for up to three months. In addition to the front windshield, it can also treat the corner glass of the front door, which is convenient for a comprehensive view of the surrounding road conditions. Cons: Costs extra.

The above methods can achieve the defogging effect, but they also have their own limitations and shortcomings.

Method 1: Most of the fog on the glass inside the original car is because the temperature difference between the inside and outside of the car is obvious, and the moisture condenses on the glass to form fog, which affects the line of sight. In the case of heavy rain, the owner can open the front and rear window glass to let the air circulate inside and outside the car and keep the temperature consistent, so that the fog can disappear easily and quickly.

If it rains and snows heavily, the owner can close the windows and turn on the air conditioner defogging function after the interior glass is fogged, and the fog on the interior glass will quickly dissipate. Today's cars basically have the front windshield air conditioning outlet and the rear windshield electric heating wire, which can better solve the problem of water mist in the windshield. Turning on the windshield wipers can solve the hanging water and fog on the exterior glass of the car, and maintain a good driving sight.

Some models are equipped with a rearview mirror heating function, which can effectively prevent fog from blurring the mirror, which is very helpful for driving in rainy days.

Method 2: Models without rearview mirror heating function can be installed with a simple rain eyebrow, and the anti-fog design of the rain eyebrow through a reasonable air diversion groove reduces the wind resistance while guiding the wind to blow to the rearview mirror, so as to accelerate the drying of water droplets and fog on the rearview mirror, and greatly ensure the driving line of sight in rainy days.

Method 3: Spraying anti-fog items In addition to these simple methods, car owners can also use professional glass anti-fogging agents to solve the problem of fogging of driving glass in rainy days. The glass anti-fogging agent can be sprayed directly on the glass to form a transparent protective film, which effectively prevents water vapor from condensing on the glass.

Usually, such an anti-fogging agent can be sprayed for about a week. If you don't have a professional glass anti-fogging agent at hand, you can also use a dry towel to wipe the glass with a little shampoo and shower gel that are often used at home, such a protective film can also effectively prevent the glass from fogging, but the effective time is shorter, but the operation is convenient.

Open windows for convection. When the fog in the car is not large, you can open a gap between the two side windows to let the air inside and outside the car form a convection, reduce the temperature difference, and the fog will slowly disappear. The principle of this method is the same as turning on the air conditioner for cold air, but it does not increase fuel consumption.

It should be noted that although it is convenient and quick to open windows for convection, it is not suitable for rainy days and heavy fog.

Air conditioner defogging. For most car owners, the use of air conditioning system defogging is the most common, 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, so the windows are fogged. Turn on the AC cooling switch in the car and let the cold air blow through the front windshield, and the fog will soon disappear.

But the biggest drawback of this method is that when it's cold, people in the car will feel cold, and the fog may reappear after turning off the cold air.

Warm air defogging use At the same time as the warm air defogging, open some gaps in the front 2 side windows, and the fog will be dried by the warm air after a while. Use warm air to remove fog, it is recommended to use it before driving on the road.

Adjust the side window air vents.

Sometimes the side windows can also fog up, affecting the driver's view of the rearview mirrors on both sides of the car. At this time, on the basis of air conditioning defogging, adjust the air outlet of the side window, so that it does not blow directly to the glass of the side window, which can generally be solved.

Defogging agents. Use a defogger. Spray the mist remover onto the inner surface of the car glass and wipe it clean to remove the glass dirt and form a protective film.

In addition, it is possible to make your own defogging agent. Mix dish soap with water at a ratio of 1:10, spray it evenly on the glass, and then wipe it off with a dry rag, which is also conducive to reducing fogging.

Now there are more and more cars.

Equipped with the function of "one-click defogging".

In humid, cold weather.

You can save the effort of manual defogging.
