What should I do if I close the windows and drive on a rainy day and there is fog in the car?

C5847F2668B1035FFCC7700C077A5E80E3C7A81For many car owners, fogging in the window has always been a headache for them, because if you wipe it with a rag, it will be time-consuming and laborious, and the point is that the effect is not good. Especially in the rainy season, dozens of days of rainy weather

1.The first relatively simple way to solve the fogging of the rearview mirror, at present, many cars have the function of heating the rearview mirror. If you also have this function in the car, when the fog is up, just turn the knob to the function icon position of the rearview mirror heating, and it will be automatically heated.

Then the rearview mirror fogging is.

2.A simple way to do if the mirror is not heated and fogged is to first apply the top of the mirror with toothpaste, and then wipe the toothpaste evenly with your hands or a dry rag. After a few minutes, wipe off the toothpaste with a damp cloth and rinse it with water.

This method is relatively simple and validated. 3. How to prevent it.

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.

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, but it does not increase the fuel consumption of the pants. The disadvantages of opening windows for convection are very obvious, it is not available in rainy and snowy weather, highways, fog, and open windows will reduce the temperature in the car.

2. Air conditioning system.

For most car owners, the use of air conditioning system to defog is the most common. Lun Zheng now has an air conditioning outlet under the front windshield of basically all cars on the market, and the air conditioner can be used to defog the air blown by the air conditioner only by selecting the corresponding gear. But whether to use cold air or warm air.

Cold and warm air have their own advantages and disadvantages, if you are in a hurry to go on the road, you can use cold air for emergency. In most cases, it is recommended that you use a warm air.

On rainy days, especially in winter, a layer of fog can create on the window glass and affect the driver's vision. When it's serious, you can't see anything clearly, and it's dangerous. How should we remove the fog?

Fog is caused by excessive humidity and temperature difference between inside and outside the car. If it doesn't rain, we can open the windows to reduce the temperature difference, and the fog will lessen. But it's not suitable when it rains.

The interior air conditioner will have a special front windshield defogging button. The owner can turn on this switch, and the air outlet under the front windshield will blow a large amount of air to the glass, quickly blowing the moisture away, and at the same time, it can reduce the temperature difference between the inside and outside of the glass, thus eliminating fog.

However, if the humidity is too high and the air conditioning effect is not obvious, you can open the windows slightly to quickly reduce the humidity in the cab. Of course, it can also be used with air conditioning, and the effect will be faster. In this process, it is still a very dangerous thing to do if the vehicle cannot pull over on the way.

So, on the one hand, you have to know how to defog, and on the other hand, you have to know how to prevent fogging. You can also add a rain eyebrow. Models that do not have mirror heating can add a simple rain eyebrow, and rain stains on mirrors that have been exposed for a long time are often difficult to clean.

In order to defog, for some models that do not have the heating function of the rearview mirror, many car owners will choose to install a rearview mirror rain eyebrow on their car. The anti-fog design of Yumei reduces wind resistance, and the wind is directed to the rearview mirror through a reasonable air duct, which accelerates the drying of water droplets and fog on the rearview mirror, and greatly ensures the driving sight in rainy days. Some car owners will say that applying soap can prevent fogging.

However, applying soap either turns the soap into soapy water and sprays it on the glass, or it softens the soap and applies it directly. Both methods are time-consuming, and if not applied properly, an uneven layer of white flower residue can form on the glass, which is not only unsightly, but also affects the eyesight, and will not last long.

There is something called a mist eliminator on the market, which is a special anti-fog product specially designed for this water mist phenomenon. After use, car glass is cleaner, clearer, and more transparent. The effect of spraying the mist eliminator once can last for about a month, or even longer.

The advantage of this method is that it works best, has a long maintenance time, and does not need to adjust the temperature and other operations when driving, once and for all. It can be said that this method is the most convenient and advanced, and it is no wonder that it is the most popular among veteran drivers.

In this case, all you need to do is turn on the car's defogging function, which will remove the fog from the glass.

I think that if you can turn on the glass defogging function, the air outlet will blow hot air into the glass, so that the fog can be removed.

The biggest causes of windshield fogging are temperature differences and humidity. The rainy weather has low temperatures and high humidity, so fog is formed, and the outside temperature is lower than the cold air, so this fog occurs inside the glass and cannot be cleaned with wipers. For a quick and effective defogger, a defogger can be used to spray the inner surface of automotive glass.

The windows are full of fog, so you can turn on the windshield wipers to brush them or stop the car and wipe them first.

I feel that maybe I can open the glass to remove fog, and blow hot air into the glass at the air outlet, so as to eliminate the fog.

In this case, the only way to do this is to turn on the car's defogging function, so that the fog is removed from the glass.

How to clear window fog on rainy days:1. Air conditioned cold air. 2.Air conditioned hot air or heat. 3.Defogging agents. 4.Fogging is cleared through the rear windshield heating wire. 5.Detergent anti-fog.

1.Air conditioning cold stove pat the air.

When fog is found on the windshield, the fastest and fastest way is to adjust the empty air outlet to the front windshield first, turn on the empty air conditioning function, with external circulation, the fog on the glass can be quickly "blown off" with the maximum air volume in about ten seconds.

2.Air conditioned hot air or heat.

If there is no fog at all in the car, then you should choose to open the air and choose hot air to blow the windshield. Similarly, use the external circulation first, select the air conditioning hot air and the front windshield air outlet, wait for about 5 minutes, and then choose to switch to the internal circulation, or close it directly. Of course, with the air-heat modulation function, the defogging effect will be faster and better.

The principle is to use warm air to dry the water vapor molecules in front of the windshield and circulate them to the outside of the car to prevent them from condensing on the glass and forming water droplets.

3.Defogging agents.

When using, just spray it evenly on the glass surface and wipe it clean with a dry towel to achieve the anti-fog effect. The principle is to use surfactants to retain a certain protective film on the surface of the glass, change the surface tension of water molecules, and make the fog beads condense into large water droplets, so as not to block the line of sight.

4.Defogging of the rear windshield heating wire.

At present, all models on the market basically have the function of "rear windshield heating", and the instructions for switching buttons are similar. Turn on the "Rear Windshield Heating" switch and it takes less than a minute to make the rear window of the bench transparent.

5.Detergent anti-fog.

Spray cleaners for window defogging are inexpensive and easy to handle. The soap method and the detergent method are commonly used. The detergent can destroy the attraction between water molecules, reduce their surface tension, and make the water molecules evenly distributed on the surface of the glass with anti-fog treatment, adhesion in the form of a water film.

The more rain falls on the glass, the greater the water film is formed, and the glass always maintains good transparency.

Ways to go to the car window fog on a rainy day: 1. Air conditioning cold air. 2. Air conditioner hot air or heating. 3. Defogging agent. 4. Defogging of the rear windshield heating wire. 5. Detergent anti-fogging.

1. Air conditioner cold air.

When it is found that there is fog on the windshield, the fastest and fastest way is to adjust the air conditioning outlet to the front windshield first, turn on the function of air conditioning refrigeration, plus the external circulation, with the maximum air volume It only takes about ten seconds to quickly "blow" the fog on the glass.

2. Air conditioner hot air or heating.

If you want to make the car completely fog-free, then you should choose to turn on the air conditioner and choose hot air to blow the windshield. Similarly, use the external circulation first, select the hot air of the air conditioner and the front windshield exit, wait for about 5 minutes, and then choose to switch to the internal circulation, or turn it off directly. Of course, with the heating function of air conditioning, the defogging effect will be faster and better.

The principle is to use warm air to dry the water vapor molecules in front of the windshield and circulate them to the outside of the car to prevent them from condensing on the glass and forming water droplets.

3. Defogging agent.

When using, you only need to spray it evenly on the glass surface, and then wipe it clean with a dry towel to have an anti-fog effect. The principle is to use the method of surfactant to retain a certain protective film on the surface of the glass, change the surface tension of water molecules, and make the fog beads condense into large water droplets, so as not to block the line of sight.

4. Defogging of the rear windshield heating wire.

At present, the models on the market basically have the "rear windshield heating" function, and the indication of the switch button is similar. Turn on the "Rear Windshield Heating" switch and the rear window will be made clear in less than a minute.

5. Detergent anti-fogging.

Car windows are sprayed with detergent defogging, the cost is very low, the operation is convenient, and the soap method and dish soap method are commonly used. The detergent can destroy the attraction between the water molecules and reduce the surface tension, so that the water molecules are evenly distributed on the surface of the anti-fog treated glass, and adhere to it in the form of a water film.

Open the windows, apply anti-fog mirror products, and open the air adjustment 1If the fog is not too big and the windows are not very cold, make a gap between the window glass on both sides so that the gas will be convection, and the temperature in the car will slowly approach the temperature of the window, and the fog will dissipate. 2.

If you are not afraid of spending money, you can buy special anti-fog mirror products from auto repair shops or online, and spray anti-fog mirrors once every half a month to half a month. 3.Turn on the air conditioner to cool, and the cold air blows against the wind.

The operation steps are to stop, operate the air conditioner, turn the indoor temperature adjustment button to the direction of the warm air, and then press and hold the defogging gear, and use the warm air generated by the heat air adjustment to dry the fog in the windshield of the car. When defogging, the air conditioning system can be converted into external circulation, so that the fresh air outside the vehicle enters the cab, and the compressor and wind speed can be adjusted to 25 or higher, which can speed up the vertical land rough defogging speed. Before each use, the window glass should be sprayed evenly and scrubbed neatly, and the glass should be transformed into layers of transparent protective film to prevent fogging transformation.

Yuzhen anti-fog mirror can be sprayed once, ten days to half a month, which seems to be the actual effect of the product. Summary: It is a more convenient way to spend money to buy anti-fog mirrors, but the validity period is not long, and the cost performance is not high.

If the fog is not too large, a gap can be opened between the window glass on both sides. In this way, the gas inside the car will be convection, and the temperature inside the car will slowly approach the temperature outside the window, and the fog will dissipate. The advantage is that it can achieve the practical effect of turning on the air conditioner without increasing fuel consumption.

In case of cold winter and rain, it is recommended that the owner switch the window glass to intermittent power supply. Take dish soap and water (the ratio is 1 6), apply it evenly on the interior glass with a sponge, dry it and then wipe it with a car cleaning towel without leaving a watermark. It can usually be reasonably maintained for 20 hours.

This situation is normal, because the temperature inside the car is different from the outside, so fog is generated on the glass, and the amount of fog is related to the size of the temperature difference.

Fog is composed of tiny water droplets (fog droplets) suspended in the air by condensing water molecules evaporating from the earth's surface and condensed by cold air. The radius of these tiny droplets is only a millimeter to a millimeter, and a single droplet is difficult to see with the naked eye, but the hundreds of millions of droplets that accumulate together can form a fog that can be seen clearly.

After rain, glass fogging treatment methods include free mixed cooling and defogging, window convection defogging, anti-fogging agent, anti-fog towel, and detergent anti-fogging. Details are as follows:

Air conditioning cooling and defogging:

There are two main causes of window fogging: low temperatures and upper-air humidity. Air conditioning can be used to remove fog from the front windshield, but if the humidity in the empty car is too high, the effect is not obvious, and the windows can be opened slightly to quickly reduce the humidity in the car.

Open windows for convection defogging:

Open windows with convection of hot and cold air. If the fog is not too high, you can open a gap between the windows on both sides. In this way, 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 disperse.

Anti-fogging agent: Glass anti-fogging agent can form a transparent hydrophobic ionic membrane on the surface of the glass to prevent water droplets from fogging.

Anti-fog towel: When fogging, wipe with an anti-fog towel, and it won't fog up. Anti-fog towels work exactly as well as defoggers.

Anti-fog in the form of a detergent:

Mix with detergent. The ratio of detergent to water is about 1:10, then apply to the inside of the front and rear windshields with absorbent cotton or a clean, soft cloth.

You can also mix household items such as shampoo and body soap with water in a ratio of about 1:10, pour them into a watering can, and spray them on the glass before driving to prevent the car glass from fogging.
