What should I do if there is always fog on my windshield when driving in winter?

1.During driving, window fogging will leave gaps in the windows or sunroofs, accelerating the air convection inside and outside the vehicle, further reducing the temperature difference between the inside and outside of the vehicle, and achieving natural defogging. Since it is caused by the temperature difference, the easiest way is to keep the temperature inside and outside the car consistent, and the fog will disappear soon after opening the window for ventilation.

However, when you open the windows in winter, it is definitely sour and refreshing. So this defogging method is really not used by ordinary people, except for antifreeze. And if the fog is too heavy, the defogging effect is also average, and it will take a long time to completely eliminate it.

Turn on the air conditioner in the car, turn on the defogging mode, and then turn on the external circulation mode, adjust the temperature to cold air, and quickly reduce the temperature in the car.

2.While this method can quickly remove window fog, it is not suitable for cold winters. If there is heavy fog on the front windshield and windows, it is recommended to turn on the air conditioner and heater to dry the fog inside the car.

However, when the warm air is first turned on, it may make the fog in the car worse. Therefore, when defogging with warm air, it is best to pull over and wait for the fog to dissipate before starting. Car air conditioners are the most commonly used defogging method.

Both cold and warm air have a defogging effect, but the principle is very different. Cold air defogging: The principle of cold air defogging of air conditioners is the same as that of opening windows, which is to keep the temperature inside and outside the car consistent, and the effect is obvious.

Basically, the fog disappears in a short period of time. But in the cold weather, the cold wind is also drunk, and it will come back as soon as the air conditioning fog is turned off, so it is not recommended to use it. Rear glass defogging is done with a heating wire instead of blowing.

3.The effect of the heating wire is better than blowing cold air to defog, but the cost of glass is relatively high, so it is generally only used in the rear windshield. Now of course there is the front glass, electric heating, defogging.

In addition to fogging, it is also necessary to try to prevent fogging when driving in winter, such as not turning the temperature of the air conditioner too high and turning on the external circulation frequently. Learning to reduce fog is actually more important than defogging. Spraying a professional defogger on the inside of the glass can not only remove the fog from the glass, but also form a thin protective film on the glass to prevent the formation of fog.

Generally, the effect of a spraying can last for about 5 to 10 days.

The internal and external circulation of the car should be opened in time, and the car should be parked in a safe and reliable place, wipe the fog on the windshield with a clean rag, and then open the window to allow the air to circulate better, and then continue to drive after the fog dissipates, and in the process of driving, the internal and external circulation and the internal circulation of the car should be opened alternately, and the wiper should be used at any time.

Windshield fogging solution in winter: turn on the air conditioner defogging function, generally about ten minutes, it will be clearly visible; When the temperature in the car is higher than the outside temperature, there will naturally be no fog; Apply anti-fog agent to the windshield to ensure that the glass does not frost in winter.

You can open the window to circulate the inside and outside air, and the fog will be eliminated naturally, or wipe the glass with dish soap, so keep the glass from fogging for about a week, you can also turn on the AC switch when you turn on the heater, and the fog can also go down quickly after the compressor works.

You can turn on the air conditioner, adjust to the gear of the glass blowing one, and blow the warm air all the time, and the fog on the glass will slowly dissipate.

1. Wipe the glass first. Because when the vehicle just started, the water temperature did not rise, so it is useless to turn on the heater, it is better to use a clean towel or a special anti-fog wool towel to wipe the glass first, this is a faster method, and so on to turn on the heating, the temperature in the car rises - some, the gas will not condense again. It should be noted that the glass must be in the parking state when cleaning, and do not wipe the glass when driving.

2. Use dish soap. Dilute the dish soap used at home with water in a ratio of 1:6, then pour it on the car glass cloth, wipe the front and both sides of the windshield, and wait until the dish soap is dry and then wipe it with a clean cloth, which can ensure that the car window glass will not fog up again for seven or eight days.

3. Turn on the air conditioner. When the water temperature of the vehicle rises to a certain extent, the heating air conditioner of the front windshield can be turned on, and the front windshield should be blown directly, and the external circulation should also be opened to reduce the temperature difference between the inside and outside of the front glass to achieve the effect of defogging. However, if the glass fogs up during driving, don't turn on the hot air, which will make the glass more serious, because it increases the temperature difference between the inside and outside of the car.

The glass should be blown dry by turning on the hot air before driving, or the hot air conditioner should be turned on in advance to dry the moisture in the car, and the fog on the glass will disappear.

4. Professional defogging agent. Spraying a professional remover can also prevent the windows from fogging. Spraying a small amount of remover on the car glass and then wiping it clean can not only remove the dirt and marks on the glass, but also form a transparent protective film on the glass, which can also be called a water displacement layer, which can effectively prevent water vapor from condensing on the glass, especially in cold winters.

For some high-end brands, the vehicle has the function of preventing the vehicle from fogging, and the air conditioning system on these models will always detect the temperature and humidity of the car, and through these two indicators to analyze the critical temperature of the condensation of the car vapor at this moment, through comparison, you can judge whether the car air will fog up on the front windshield.

If the system detects that fogging is about to start, the air conditioning system initiates a series of defogging operations, such as adjusting the temperature, wind direction, air volume, external circulation, etc.

Yes, it is possible to turn on the air conditioner, but it is also possible to reduce the fog on the glass by opening the windows, or you can prepare a cloth to wipe it in the car.

At this time, the air conditioner should be turned on, because the air conditioner can balance the temperature inside and outside the car, so that the fog on the glass will disappear.

Yes, when driving in winter, if this always happens, you should turn on the air conditioner in time.

1. Turn on the hot air conditioner.

This trick is no stranger to many friends in the north, after the vehicle clears the snow, the window will leave a layer of mist, at this time turn on the heating, the fog will be clear quickly. Nowadays, some cars have a one-key defogging function, which also uses this principle to achieve the defogging effect.

2. Open the window.

Sometimes the fog on the windshield is formed by the hot air we exhale. At this time, open the window to dissipate heat. However, this method may work in the south, but it is not recommended in the north, because the cold after opening the window is unacceptable to many people.

3. Chemicals.

This thing can be bought in many 4S shops and car repair shops, in fact, these chemicals are applied to the windshield, and then the car glass will not continue to produce fog. However, it remains to be seen whether this method is harmful to the human body. So everyone should still be vigilant.

4. Refrigeration and defogging.

The reason why the windshield produces fog is entirely because the temperature on the outside of the windshield is not the same as the inside of the windshield. As long as we adjust the temperature of the two to a close value, the fog will naturally disappear. However, it also takes courage to turn on the cold wind in winter.

If you're not a person who can handle the cold, it's still not advisable to try.

The main reason for windshield fogging is caused by the different temperature difference between inside and outside the car, at this time we only need to eliminate the temperature difference between inside and outside the car, the fog will naturally be eliminated, but the disadvantage of this is that the speed is too slow, you open the window and wait for the natural circulation of air, it is estimated that you have to wait for a long time, because the temperature difference needs a slow process to eliminate, the car heating and cooling device is broken can not be used There is also a way, the winter windshield is easy to fog up, you can use the family tableware dish soap, according to 1:1 and diluted with water, Apply a towel evenly to the glass to keep the glass water foggy for about a week.

In the winter, when we turn on the heater, be sure to turn on the AC switch to let the compressor work, so that the fog goes down very quickly! (Note: The temperature can be adjusted to the desired temperature).

Now there is a special anti-fog spray for glass, wipe the window glass clean and then spray it on the inside of the glass, and wipe it evenly with a cloth. A small move can prevent the occurrence of glass fogging, reduce potential safety hazards, and it is more convenient to use.

When driving on ice and snow roads in winter, you should not drive in a higher gear, but should control the power of the vehicle to leave room for improvement, and minimize the number of gear changes to prevent accidents. Maintain an even driving speed when driving, reduce the speed of the vehicle, reduce or avoid changing lanes and overtaking vehicles as much as possible, and strictly prohibit the use of emergency braking.

The most effective way to do this is to spray a car anti-fogging agent, which can form a protective film for the glass and prevent water vapor from forming a fog layer. It generally lasts for about five days, and it can be purchased at a general car supply store. This is the most effective approach.

Many cars today are equipped with this feature, the front windshield is heated by blowing hot air, and the rear windshield is heated by resistance wires. In both cases, the water mist on the glass is dried by hot air, and the fog will increase when it is first opened, but it will subside after a while.

You can turn on the heater in the car, so that the temperature in the car is high, and the fog will dissipate, or put a water-absorbing cloth in the ** console to wipe it.

Then you can buy a special film, so that it can block the generation of fog.

The best way is to find the glass defogging switch on the central control, after opening it, there will be hot air blowing out, and there will be no fog on the glass.

The solution to fogging the windshield before driving in winter is as follows:

1. Warm air defogging.

With the increase in the temperature of the water tank, the temperature of the air outlet will slowly rise, so that the glass will have a slow heating process, and the windshield will slowly adapt to this temperature change, so that the windshield will not fog up for a long time. As a veteran driver, I must love this one the most.

2. Cold air defogging.

This method is the fastest of all the defogging methods, because in winter, the outdoor temperature is low, and if the cold air is blown, the temperature of the windshield is similar to the outdoor temperature, and the cold air can quickly remove the moisture on the glass.

3. Open windows to remove fogging.

By opening the window to let the outdoor air into the cab, keep the temperature difference between indoor and outdoor is not large, so as to ensure that the temperature of the windshield is constant, and it will not be easy to fog up, the principle of this method is similar to the cold wind defogging, it is still difficult to use for a long time in winter, if it is sunny day, once there is rain and snow, it is more embarrassing.

4. Wipe and defog.

Usually when we wipe the windshield of the vehicle, try to wipe it with a wet towel dipped in dish soap or soapy water, and after it dries naturally, wipe it again, after three times in a row, a smooth film will be formed on the windshield, so that when the fog appears on the glass again, it can quickly dissipate and will not affect our driving.

5. Defogging agent defogging.

The fifth method is to spray defogging agent on the windshield, it is recommended that you prepare this kind of car glass anti-fogging artifact, as long as you spray and wipe on the glass, you can form a protective film to prevent the glass from fogging.

Fogging the windshield before driving on rainy days can be done as follows:

1.Use warm air to blow the windshield.

Adjust the temperature of the air conditioner to the position of the warm air, automatically adjust the temperature of the air conditioner, rotate the direction switch, adjust to the blowing glass, and the fog will disappear after a while, and the effect is very obvious.

2.When the heater is turned on, the external circulation is turned on and the compressor is turned on at the same time.

Dehumidify the air sucked in, so that the defogging effect is particularly fast, that is, the air conditioning dehumidification function, these relatively dry air continues to advance to the warm air tank, and the heated dry air blows to the windshield, and the water vapor on the windshield is instantly absorbed.

3.Use specialized defogging and derounding products.

Before driving, spray the defogger evenly on the surface of the window glass and wipe it clean with a dry towel. The principle of using fogging remover is that it will form a certain protective film on the surface of the car window, changing the surface tension of water molecules, so that the probability of fog beads forming is reduced.

Precautions for driving in rainy weather:

Prevents tires from slipping

When the ground is wet in rainy weather, it is easy for tires to slip sideways, so you should not brake sharply when cornering, and it is best to slow down in a straight line before entering the corner.

If you encounter an emergency and need to brake suddenly, don't panic, either twist the steering wheel to avoid, or brake in a straight line, do not brake and avoid at the same time, this will not play any role.

Slow down

Regardless of the width of the road and the condition of the road surface, slow down when driving in the rain, pay attention to the distance between the vehicles in front and behind and your own car at any time, and be mentally prepared to take various emergency measures in advance.

In rainy days, the visibility is low, the visibility is poor, and the vehicle's braking distance and other emergency performance will also be reduced, so it is necessary to slow down in advance and leave enough time and space to deal with the situation to ensure safety.

Keep an eye out for pedestrians

Due to the fact that pedestrians hold umbrellas in the rain and cyclists wear ponchos, their vision, hearing, and reaction are restricted, and sometimes they are in a hurry to cross the sharp turn, and often panic and slip when the vehicle is approaching, which catches the driver off guard.

In this case, the driver should slow down, be patient and avoid, choose a safe place to park if necessary, and do not rush with pedestrians and bicycles.
