How can you prevent your car windshield from fogging up on a rainy day

Hello, in winter and rain, the front windshield of the car can be fogged up, and the warm air can be blown against the glass, so that the fog can be removed. In fact, there is another way, buy a bottle of defogging, spray the defogging agent and evenly apply it to the glass with a rag, and then blow dry, so that the mist cannot be formed. Apply at least one week at a time.

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.

1. Spraying anti-fogging agents and other preventive methods.

Spray a little defogging agent on the car glass window (inner wall) and 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.

2. Hot air defogging.

When turning on the hot air defogging, due to the humidity in the rainy days in the south, the temperature in the car is not high enough at the beginning, so the fog may become larger in a short time, but when the temperature continues to rise, the air in the car is getting drier and drier, and the fog can be eliminated naturally.

When it rains, the windshield of the car will generally be fogged, so it will block the driver's vision, so how to prevent the glass from fogging when driving in rainy days?

1. When the driver drives in a rainy day, he must avoid rainwater entering the car, and the windows can be closed at this time. However, if the windows are closed, the humidity in the car will be high, and it will be difficult for the driver and occupants to exhale air out of the car. At this time, the external circulation can be opened, which is conducive to the exhaust of fog in the car.

2. When driving on a rainy day, when the rain is not heavy, the driver can keep the temperature of the front windshield and the indoor and outdoor balanced, which can alleviate the fogging of the front windshield.

3. When it rains heavily and it is inconvenient to open the car window, you can also use the method of turning on the air conditioning in the car. When the air conditioner turns on the cold air, the fog on the glass will generally subside, and the effect is also better.

According to the above analysis, when driving in rainy weather, if the driver wants to prevent the glass from fogging, the above measures can be adopted to ensure driving safety.

Don't reach for the fog while driving.

A few days ago, Wan, who was about to get his driver's license, drove a private car and braved the cold rain to send his girlfriend home in the middle of the night. It's warm inside the car and cold outside, fogging the front windshield. I couldn't see anything clearly in front of me, so Wan drove and wiped the glass with his hands.

Driving north to south along Zhongshan North Road to the vicinity of the Nanjing Hotel, the car was filled with fog, but Wan was still driving at a speed of 50 kilometers per hour. Suddenly, he vaguely saw a motorcycle riding in front of him. At this time, the distance between the two cars was only six or seven meters, and he urgently applied the brakes, resulting in a serious car accident.

Expert advice: Novices must be careful when driving in autumn and winter, and pay attention to accumulating experience in dealing with bad weather. The windshield is covered with fog, which can completely adjust the air vent space in the car, allowing the warm air to blow the windshield for a while.

Even if you use your hand to wipe the glass, you should park your car in a place that does not affect traffic, and you should not wipe it while driving.

Once the owner finds that the fog affects his vision, never wipe the windshield with his hands or cloth. In addition, when driving in the morning, you find a thin layer of ice on the windshield, don't let it melt on its own for fear of trouble, because this thin layer of ice will also affect the vision. The way to clear it is also to let the warm air blow on the windshield for a few minutes, wipe it with a cloth after the ice turns into water, and then drive on the road.

It will take a little time, but it's safe.

Effective precautions.

It is rainy in autumn and winter, and the empty windshield is easy to fog and frost, which affects the line of sight and brings hidden dangers to driving safety, and the driver cannot take it lightly. There are a few ways to prevent frost on your windshield, and car owners may wish to give them a try:

1.After the engine heats up, turn on the heater, temporarily close other air ducts, and concentrate the air to blow directly on the surface of the glass, which can quickly blow away the frost.

2.Open the air to adjust the temperature in the car, eliminate the fog in the car, and make the frosted glass melt quickly.

3.Apply a thin layer of glycerin or alcohol to the windshield to prevent frost from forming on the glass surface for a short period of time.

4.Dissolve the dishwashing detergent in water and apply a clean cloth to the inside of the windshield. There will be a lot of bubbles.

Just wait for a while for the foam to disappear on its own, and the dish soap film left on the glass will effectively prevent frosting on the glass within 2 hours. When the temperature inside the car rises, wipe off the liquid film from the glass with a clean, damp cloth.

5.If the windshield is frosty, stop to scrape off the frost and wipe it off with a dry towel. Avoid driving reluctantly or wiping while driving to ensure driving safety.

6.Mix dish soap with water in a ratio of 1:10, put it in a sprayer, and spray a thin layer on the window, which can effectively prevent fogging for a period of time after drying.

The solution to the fogging of the windshield in rainy days: 1. Turn on the air conditioner: you can turn on the AC in summer, blow the front windshield, and the external circulation, and blow it away soon.

In winter, if the water temperature does not come up, adjust the temperature to warm air, turn on AC, and blow the front windshield. When the water temperature rises, you can turn off the AC and only use the heater, and be sure to use external circulation. 2. Open the window:

This method is more suitable for light rain, and the rain will not come in in large quantities. Generally speaking, blowing for tens of seconds can play a role in removing the fog cavity. The principle is that the temperature in the car can be lowered, so that the moisture is not prone to condensation.

Generally, it is better to use this method in winter, because the air is dry in winter, and opening the windows can not only cool down but also take away the moisture in the car, and the moisture outside the car is also heavier in rainy days, so it will not take long for the window to close and frost. 3. Windshield defogging defogging agent: There are many brands of fog repellent, just see a suitable one, and the fog repellent can ensure that a faction does not fog up for a period of time.

The automotive glass fog repellent is to form a layer of nano U002F micron protective film on the glass surface; And this protective film has a hydrophobic (repulsive) effect. As a result, rainwater will automatically shrink into round droplets when it hits the surface of the glass, which will slide off the glass on its own. The auto glass fog repellent mainly changes the properties of the surface of the auto glass, from hydrophilic to hydrophobic, so as to achieve the purpose of rainproof.

Car window fogging is most likely to occur in two situations, one is rainy days, the other is winter, in winter, you will generally find that the car window is fogged before driving, which is easier to deal with; But whether it's summer or other seasons, maybe when we are driving, a rain falls, and the windows will suddenly fog up, in this case, sometimes it can be a mess to deal with. It's easy to understand why car windows are easy to fog up when it's cold in winter, but why are car windows easy to fog up on rainy days? Actually, there are two main reasons.

First of all, when it rains, the temperature difference between the outside of the car and the inside of the car is relatively large, even if it is a rainy day in summer, there will be a temperature difference between the inside and outside of the car, the temperature outside the car is low, and the temperature inside the car is high, then the temperature of the window glass will also be reduced at this time, and the moisture in the car will condense into water mist after encountering the cold window.

The main reason is that there will be a temperature difference between the inside and outside of the car on rainy days, the temperature outside the car is low, the temperature inside the car is high, and the moisture in the car will condense into a mist after touching the window. The easiest way to remove the fog is to turn on the air conditioning hole in the car, turn on the liquid head defogging button to the maximum, let the air conditioner cold air blow vigorously against the car window, and soon the water mist can be removed.

When it rains, even if it is a rainy day in summer, there will be a temperature difference between the inside of the car and the outside of the car, the temperature outside the car is low, the temperature in the car is high, then the temperature of the window glass will also be reduced at this time, and the moisture in the car will condense into water mist after encountering the cold window. When the window is fogged, use cold air to defog it, turn on the air conditioner, press the A C button to blow the air conditioner, select the wind direction as blowing the front windshield, and adjust the air volume to the maximum. First of all, it blows cold air, which can quickly reduce the temperature of the car window, which is equivalent to forming a wall on the windshield, a wall of wind, preventing water vapor from gathering fog on the glass, so that the fog potato sock will be quickly swept away.

When the owner travels on a rainy day, he hates the fog on the car glass the most, which greatly affects the vision of the car owner, so how to remove the fog on the car glass on a rainy day?

1. The air conditioner of the general vehicle has a defogging mode, after the owner turns on the defogging mode of the vehicle, the fog will basically dissipate, if there is no defogging mode, you can turn on the cold air of the vehicle, and switch to the external circulation mode of the vehicle at the same time.

2. The owner can lower the window to open a small gap, so that the air inside and outside the car is convection, when the temperature difference between the air inside and outside the car is not much different, the fog will naturally dissipate.

3. The owner can buy defogging spray, first wipe the mist dry, and then use the defogging spray, a protective film will be generated, the fog will not be produced again, and the owner can also achieve a similar effect by using soapy water.

4. The owner can place a rag on the dashboard, and wipe it dry in time after finding that the window is fogged, which can quickly solve the problem, but the fog will be frequently generated, and the owner often needs to wipe it repeatedly.

On rainy days, the interior glass of the car can easily be covered by a layer of fog, and some novice drivers are a little caught off guard and don't know how to deal with this situation. Let's talk about how to eliminate the fog that is easy to fog up in the car on rainy days. <>

How can fogging be removed from the interior glass of the car?

The first method is to use the soap removal method, which is simply to wipe back and forth on both sides of the window with soap, 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 method is to prepare a bottle of defogger, spray it on the car window, wait for a while and then wipe it clean with a dry towel or paper towel, after using the defogger, the car window can be kept no longer 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. <>

If you don't have soap and no fogging agent, you can open a small gap in the window on a rainy day to keep the car ventilated, which can also alleviate the fogging of the window to a certain extent. The air inside the car is circulated, and the water vapor generated by breathing will drift away with the air, improving the fogging situation. If it rains heavily and is accompanied by strong winds, then it is not advisable to open the windows for ventilation.

Use your car's air conditioner to blow away the fog

Finally, 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. Defogging with air conditioning system It is a common practice to use air conditioning to defog out. Turn on the cold air to blow the glass, and the defogging effect is very straightforward.

Second, the effect of hot air blowing fog with hot air blowing glass is better than that of cold air, but the effect is slower than that of air conditioning. When the hot air dries the moisture in the car, the glass will no longer fog up for a long time. It is best to turn on the hot air first when parked, and then pick up a rag and wipe it again.

In addition, opening the external circulation during driving can also prevent fogging to a certain extent.

3. If the fog is not big and the temperature outside the car is not very low, you can lower a part of the windows on both sides to let the air in the car convection, and the temperature in the car will slowly approach the temperature outside the car, and the fog will disperse.

Fourth, the method of detergent anti-fogging blending "anti-fogging agent" to prevent fogging has been well known to many people. The ratio of washing spirit to water is about 1:10, and then use absorbent cotton or a clean and soft cloth dipped in it to apply it to the inside of the front and rear windshields, and then wipe off the remaining watermarks left on the inside of the glass after drying. It will work better with an air conditioner.

You can turn on some air conditioners to adjust the temperature in the car, or open the windows or sunroofs, which can achieve the effect of defogging.

You can put potatoes on the glass so that you can get rid of the fog, and you can also see the road ahead, so you will have a good view.

You can open a slit in the window to allow air convection inside and outside the car, and you can also directly use the window defogging function, just click the button.

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.
