What to do if the front windshield of the car fogs up on a rainy day

The first method is to use the soap elimination method. Just take the soap and wipe it back and forth on both sides of the window, wait until the oil stain has hardened, and then gently wipe it off with a clean towel. In this way, the surface of the glass is equivalent to adding a layer of wax film, and when traveling on rainy days, there will be no fogging on the glass in the car.

The second way is to prepare a bottle of defogger. Spray on the car window, wait for a while and then wipe it clean with a dry towel or paper towel, after using the fogging agent, the car window can be kept without fogging for about a month, and the durability is still very long. I recommend everyone to use a defogger, because its ** is cheaper, and it lasts for a long time, it is very convenient to use, and female drivers can easily operate it.

Use your car's air conditioner to blow away the fogFinally, let's talk about a way to remove fogging, that is, using the car air conditioner, turning on the air conditioner can blow an appropriate amount of cold air, and then adjust the air outlet of the air conditioner to an upward angle, and then blow in the direction of the car window after a while, which can also effectively prevent fogging on the car window. When it rains, the sight inside the car will also be affected to a certain extent, so you should slow down and concentrate. Especially when crossing intersections, pay more attention.

If you encounter a rainy day, try not to go out unless there are special circumstances.

1. Open the front and rear windows to let the air circulate inside and outside the car, the temperature is consistent, and the fog can disappear quickly;

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

3. Turn on the cold air of the car air conditioner and turn the air outlet to the windshield in front of the car, which can quickly remove the glass fogging;

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

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

6. Use a professional anti-fogging agent, spray it evenly on the surface of the cleaned glass, and then wipe it with a clean towel after forming a protective film on the inner surface of the glass.

The first way is to open the windows for ventilation

If there is not much rainfall, just some misty drizzle, then we can choose to open both the front and rear windows with a slit, preferably in the form of a diagonal. In this way, as long as the car is moving, the air from the outside can enter the car and circulate inside, and finally exit through the rear window. Without the temperature difference, the fog disappears naturally.

The second method is to heat and defog

If the rainfall is relatively heavy, then we can't open the windows for ventilation, so we can only take other ways to remove fog. Since there is fog on the window, then we can directly use hot air to evaporate it, so that the fog will disappear, and many cars have a one-key heating defogging button, as long as it is opened, it can be defogged. It's just that this will make the fog worse in the first few minutes, so use it when it's safe to do so.

The third method is refrigeration and defogging

If the car is moving, it is somewhat dangerous to use heating to defog because it will block the view, then at this time we can turn on the air conditioning to defog. Since the fog is caused by the temperature difference, if we lower the temperature inside the car so that the temperature inside and outside is the same, then the fog will not be generated. However, this method is difficult in the winter and can only be used on demand.

The fourth method is chemical agents

There are a lot of defogging sprays on the Internet, as long as it is sprayed on the windshield, the fog will not continue to be generated, so car owners who have the conditions can buy one or two bottles and put them in the car. If you want to save a little money, you can also use soapy water or soapy water, which also has the same function.

Related Notes:

When the owner encounters fogging in the front windshield of the car in rainy days, you can first press the A C switch button, then open the front windshield defogging button, and adjust the temperature to the lowest, and then adjust the air volume, and the fog on the front windshield can be eliminated after a while. If fog is found on the rear windshield and exterior mirrors, the fog can also be removed by opening the rear windshield heating button when the front windshield is being defogged.

In addition, it should be noted that the heating system is used to remove the fog in winter, if the car has just started, the air conditioning will not be started temporarily, wait for the engine to preheat for a few minutes, after the water temperature comes up, start heating, open the external circulation, adjust the air volume to the maximum, and then open the front window defogging button, and the fog will disappear in a few minutes. This method is also suitable for fogging the outside of the glass in the summer.

And if the owner encounters fogging of the driving glass in rainy days, he really can't remember which button to press, and he should try to pull over as much as possible depending on the situation.

Air Conditioning Heating Method:Fogging is removed by reducing the temperature difference, and windshield fogging in cold or rainy and foggy seasons is often caused by the temperature difference between the inside and outside of the vehicle. The air conditioning and heating system can reduce the temperature difference between the inside and outside of the car, and by the way, it also has the function of drying air.

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

Anti-fogging agent is used to prevent fogging:The method of mixing anti-fogging agents to prevent it has been well known to many people, the ratio of washing spirit to water is about 1:10, of course, anti-fogging agents can also be bought ready-made, and then applied to the windshield.

Then wipe the inside of the front and rear windshield with absorbent cotton or a good cloth, and then wipe off the remaining watermarks left on the inside of the glass after drying.

It should be noted that when using the defogger, car owners only need to spray it evenly on the glass surface and then wipe it clean with a dry towel. The ** of defogger on the market ranges from tens of yuan to hundreds of yuan, and the ingredients are not much different, and the only difference may be the durability.

The front windshield of the car fogged up on a rainy dayYou can turn on the air conditioner of the car and quickly blow the windows with strong winds to defog it. First of all, the car air conditioner blows cold air, which can quickly reduce the temperature in the car, and blowing the window can quickly reduce the temperature of the window, so that the temperature of the inner surface of the window can quickly reach the same temperature as the outside of the car, so that the fog can disappear quickly.

However, if the air conditioner is turned off at this time, after a while, the temperature in the car will rise again, and fog will be formed, so it is generally necessary to turn on the air conditioner for a while and use the air conditioning compressor to remove the moisture in the car, so that you can keep the car free of fog for a long time.

On rainy days, avoid fogging your car windows

1. Open windows for convection.

If you find that the fog in the car is not large, you can open a gap in the windows on both sides, so that the air inside and outside the car will form a convection, the temperature difference will also decrease, 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. At the same time, it should be noted that the opening of the window should not be too small because of the rain, and the opening amplitude of the window should be adjusted according to the size of the rain to be effective.

2. Detergent anti-fogging.

Moisten the soap with water to soften it, then apply it evenly to the entire surface of the glass (be sure to be even), and when the soap on the glass is dry, remove it with a paper towel or newspaper. Be careful not to use a towel, as it is easy to leave fine crumbs with a towel. However, this method has a small disadvantage of defogging in rainy days, that is, a small amount of soap will remain on the glass, but it will not affect the overall vision.
