How should I properly defog a car window when it fogs up?

We all know that in fact, for most of you now, whenever we start school, there will often be some impression options, such as the weather and direct changes, which will cause my car window to fog up, so some people will produce such fish, or when the car window is fogged, how to properly defog it? After this question, it can't be seen that since I think we should also judge the change in weather at this time, we should use the right switch, let's take a closer look.

1 Judge the change in the weather

We all know that the fog on the general car window is mainly caused by the change of weather in winter and rainy days, so it is caused by a large indoor temperature difference, so in this case, generally in winter, we should start the nephew control, this time should also be opened at the same time. The front windshield defogging switch, and when it rains, we should turn on the external circulation and similar switches, as well as the front windshield window, defogging switch, these are the same operations.

2 Use the switch correctly

We all know that in fact, whenever we use a variety of switches, we need to be logical, if we are married, we must learn to discern, because everyone switches its function or nature is different, if you use the wrong one, then you will not be able to achieve the effect we want.

So we should pay more attention to this aspect of the problem in our daily life, for everyone, understanding this aspect of the problem is of certain benefit to us, and now we live in such an era in fact, I think that the loss of every kind of vehicle is to coax, do not take the corresponding ways and methods, but also pay attention to some specific ideas. There is a great danger in itself when it is used for filming, especially if the windows are fogged, we can have a blurry feeling, and it can also seriously affect the driver's vision.

Use a towel to wipe off the fog: stop the car first, because wiping the fog while driving will distract you and affect driving safety; Use open windows to remove fog: You can open the window to a gap, and the air entering the vehicle will lower the temperature inside the car, and the fog will slowly dissipate.

You can close the windows and turn on the air conditioning system in the car, and the fog will dissipate automatically, or you can spray the windows with a defogging agent and wipe them clean with a rag.

In addition to using hardware methods to remove fog, physical defogging is also a good way to try. Apply soap or dish soap evenly on the inside of the window glass, and then wipe it clean, which can completely avoid fogging, maintain the effect for about 3 days, drive in rainy weather, use the same method, apply it to the rearview mirror, can prevent rain from blocking the rearview mirror.

Through the window defogging spray on the market, spraying and wiping the window glass can play a role in preventing fogging, according to the owner, the last time is about a week, and the effect is still good.

For rain and snow weather, eliminate the fogging of the car window, in order to prevent summer and winter driving, overheating and overcooling in the car, there are also many car owners who choose to use the method of poisoning to eliminate, but the effect is slow, and it takes a certain amount of time to run-in.

For example, driving in winter, it is easy to fog up, the owner will still choose to use warm air to eliminate, but will adjust the wind speed to the maximum, and point the air conditioning wind direction to the front windshield, although the defogging effect is slow, but to avoid the invasion of cold wind.

Xiao Kun said that the car, so that you don't have to worry about driving a car!

First of all, the most common is that some drivers will take a towel, when the water mist is larger, use a towel to dry the glass, but this method has great drawbacks, in addition to the need to wipe once from time to time, the driver will affect the normal driving operation every time he wipes the glass, and secondly, it will also affect the safety of driving. From this point of view, this most traditional method is not the best choice.

In winter, it can be removed by opening a window or turning on a cold wind.

The reason for the fogging of automobile glass is that the temperature difference between "internal heat and external cold" is large, and the hot air in the car encounters the cold glass water vapor condensed on the inside of the glass, which will affect the driving speed, and may affect the driver's vision and cause serious traffic accidents.

1. Spraying anti-fogging agent and other preventive methods: spray some defogging agent on the car glass, and then wipe it clean, you can remove the dirt and stains on the glass window. This not only cleans the glass, but also forms a transparent protective film that prevents moisture from condensing on the glass to form a fog layer, especially in cold winters.

2. The cold wind blows away the fog: the cold air is called, and the air volume is turned up, the cold wind blows on the glass, and the fog is quickly blown away, the speed is very fast, and the glass is very clean.

3. Air conditioning heating method: the method of reducing the temperature difference: blowing hot air on the glass with warm air in winter, quickly increasing the temperature of the front glass, reducing the temperature difference between the inner and outer surfaces of the glass, and preventing the fog vapor of the front windshield from being too heavy in a timely manner.

4. Open window convection method: When the fog is not large, you can open a slit in the window to let the air inside and outside the car convection. When the temperature inside and outside the car is close, the fog will disappear naturally. However, this method is not suitable for cold winters and rainy days.

In fact, the windows are always fogged up due to the large temperature difference between the inside and outside. If it is foggy outside the window, it is generally caused by rainwater condensation, and it is okay to scrape it with a wiper, but if it is a frost in winter, you should wipe it with water, and do not use a wiper to scrape hard, so as not to damage the wiper.

If there is fogging in the car window, you can open the window to let in ventilation to let the air inside and outside circulate, or turn on the air conditioner to blow the windshield in front of you, which can effectively deal with the fogging of the car window.

And whether it is fogging the windows inside or outside the car, you can use dish soap to pour on the towel to wipe the glass, and after a few minutes of foam disappearing, the fog on the window will be very effective to deal with, and the time to defog is longer, and the fogging is more thorough.

The use of defogging agent has a good effect, and there are also defoggers on the market that prevent glass fogging without using air conditioning, ** is not expensive, basically within 100 yuan at any price, and the effect of different brands is not the same, so I will not recommend it here. In short, fogging inside and outside the car is not a trivial matter, because it is still very dangerous to block the view.

I know! I'm an old driver! The fog outside the car must have been due to the weather!

No one can solve it! The fogging of the windows in the car is a large temperature difference between the inside and outside! It's better to turn on the air conditioner!

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.

**It's sold online, and that spray is good for a while.

The dirt solution is the soap cube in the car.

Method 1: If you find that the windows of your car are fogged, don't panic, you can open the windows on both sides of the vehicle, and the width of a fist is fine. This causes convection of the air in the car, blowing the moisture away, and the fog quickly dissipates.

Method 2: Turn on the fan and refrigeration switch in the car, and when the cold air blows on the glass, the fog will quickly 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 feel cold in the winter, so you might want to give it a try.

Method 3: In fact, you can also get 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.

Method 4: Preventive methods such as spraying defogging agents. 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.

Hope mine can help you, hope!

There are two ways to defog the windows: turn on the cold air to remove it, which is faster. Turn on the hot air to remove, relatively slowly.

You can turn on the hot and cold air in the car, or you can spray some glass water on the windows.

Hello! The reason for the fogging of the car window is that the temperature difference between "internal heat and external cold" is large, which may be more than ten degrees, and even reaches 20 degrees in winter, so that fog will appear on the glass. Here are some ways to share with you how to prevent fogging and defogging.

The first type of method - with special defogging products.

In many markets and places such as auto parts cities, there will be some stalls selling special products for defogging and anti-fogging, such as defogging agents or fog towels. This kind of defogging agent is sprayed on the inner surface of automobile glass, and wiped clean, while removing glass dirt, it can also form a thin layer of transparent protective film on the glass, which can prevent the condensation of water vapor on the glass and form a fog layer, spraying can prevent fogging for ten days - half a month. Of course, the way to spend money to save trouble, for a simple problem like fog, spending this money must not be the most cost-effective.

The second type of method is fenestration convection.

If the fog is not large, we can open a gap in the windows on both sides (this cannot be done when it is raining), so that the air inside the car will 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, but this method is not suitable for all situations, such as in the cold winter and when it rains. This is a good method when it is not raining and the temperature is acceptable, but the disadvantage is that it is not suitable for use at high speeds.

The third type of method is the use of air conditioning systems.

We encounter windshield fogging in winter and rainy days, I believe many friends have used the air conditioning system to remove fog, in fact, there are some tips here. I believe that many friends have questions and controversies about the use of cold air or warm air defogging effect, in fact, this problem is two-sided, and it is discussed due to different situations.

The usual practice is to turn on the fan and refrigeration switch in the car, so that the cold air blows on the glass and the fog will soon disperse, and the effect is quick and direct. This is because the cold air blows onto the glass, forming a "cold film" on the surface of the glass, preventing carbon dioxide from condensing on the glass and having a defogging effect. One of the biggest drawbacks of this method is that the people in the car may feel very cold, just imagine that in rainy days and winters that are prone to fog, the taste of blowing air conditioning in the car is really uncomfortable!

Blowing for a few minutes may turn off the air conditioner, and after a while the fog starts to hang on the glass again, and the air conditioner ...... turned on againThis repeated operation is inconvenient and the temperature in the car will be very unsuitable, and the operation of the head down has caused certain hidden dangers to safety. Of course, if you are physically strong or have just finished an intense workout, this method can also be useful.

So can you use hot air to remove fog? The answer is absolutely! Turn on the hot air, which will not add additional energy consumption, but also drive comfortably, killing two birds with one stone!

If it's outside, it's definitely a wiper brush, but if it feels cute, then you have to wipe it with a dry rag, if it's in the car, you must turn on the air conditioner for his cook, and slowly you can get rid of the rain and fog, the fog is like this, and you can slowly get rid of it with air conditioning.

The windows have a defogging function.

If it's winter, it's recommended that you turn on hot air.

Screw the hot air turn knob to the setting with a window sign.

Blowing glass will do the trick.

When driving, don't be very big, generally the hot air is the heat of the engine, and in the summer, you can turn on the cold air.

Turn on the air conditioner when necessary.

If you want to defog out the window, you can turn on the air conditioner of the car, as long as the temperature is higher than the temperature outside the car, you can effectively remove the fog.

The quickest way to do this is to blow the air conditioner out of the air vent position, aim it at the front windshield, and then use the cold air.

The most common way to do this is to turn on the fan and refrigeration switch in the car, and the cold air will blow to the windshield and quickly "sweep away" the fog.

The easiest way is to turn on the air conditioner and use the cold air to blow faster.

The method of defogging the front windshield of the car is as follows:

1. Open the window;

2. Use defogging agent;

3. Turn on the air conditioner heater;

4. Turn on the defogging function of the car;

5. Apply dish soap to the car windows with water or soapy water;

6. Put a dehumidification box in the car;

7. Wipe with a towel;

8. Turn on the refrigeration switch by increasing the air volume appropriately.
