How to solve the fogging of the front glass? What to do if the front windshield in the car keeps fog

The solution to fogging up the front windshield of the vehicle is as follows:

1. Air conditioning and heating method. The cause of fogging of car windows is usually caused by two conditions, one is that the humidity of the air in the car is too high, and the other is that the temperature gap between the inside and outside of the glass in the car is relatively large, and defogging is to solve these two problems. 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.

Advantage: Keeps the interior of the car warm in winter.

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

2. Defogging by dehumidification. The air conditioner refrigeration and dehumidification function is used to reduce the air humidity to remove fog. Especially obvious is that when the temperature in the car is relatively high, coupled with the number of passengers, the air humidity in the car is very high at this time, and it is more likely to fog up.

Advantages: fast speed and obvious effect.

Disadvantages: It will be colder in winter.

3. Use anti-fogging agent to prevent fogging. First, wet the entire windshield with the anti-fog agent, wait a short time, and then wipe the anti-fog off with a clean, soft towel. 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.

Advantages: low cost and good effect.

Cons: Short duration.

1.It may be because the front windshield has been used for a long time, and tiny holes will appear in the front windshield. Other things such as dust in the air will remain in the holes, slowly forming a film of oil.

2.Or because the front windshield has not been cleaned in a professional beauty shop for too long, the usual dust, bird droppings, fruits, tree sap and other things will slowly form a layer of oil film on the surface.

3.It is also possible that when driving on the road, the exhaust fumes from the front car are oily, and oil mist will slowly accumulate on the front windshield. In this case, if the window glass is open, there will be oil mist on the inner windshield.

4.It's also possible that an oily object has splashed on the front windshield of the vehicle, which is why this is the case.

5.Or when you eat instant noodles, self-heating hot pot and other oily water vapor in the car, there will be oil mist on the inside of the front windshield.

Remove the oil mist from the front windshield.

1.Removing the oil film from the front windshield requires purchasing a professional cleaner online. After buying, you need to wipe the front windshield clean first.

2.The main thing is to remove dust and fine particles, then put some clean water on the windshield and wipe it back and forth with an oil film remover and a clean wet towel.

3.Wipe until no oil or oil mist is present, then wash the foam with clean water and dry the windshield to remove the oil and oil mist.

4.If you don't want to clean it yourself, you can go to a car detailing shop to have it professionally cleaned.

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 inhaled air, so that the defogging effect is particularly fast, which is the dehumidification function of the air conditioner, these relatively dry air continue to advance to the warm air tank, and the heated dry air blows to the windshield, which instantly absorbs the water vapor on the windshield.

3.Use specialized mist removal 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 stop if necessary, and do not rush to pedestrians and bicycles.

In winter, due to the large temperature difference between the inside and outside of the car, many friends will encounter fogging of the car window, especially in rainy and snowy days. Don't ignore fogging of the windows, which can affect the driver's vision and pose a safety hazard to the vehicle. So, what to do about fogging up the car windows?

Here are a few tips for defogging.

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

Turn on the fan and refrigeration switch in the car, and when the cold air blows onto the glass, the fog will quickly seep and 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 of the car feel cold during the winter months, so you might as well give it a try.

You can also receive 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.

Preventive methods such as spraying defoggers are used. A little defogging agent is sprayed on the car glass, and then wiped, and 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.

Hello! The windshield of the car is fogged because there is more moisture in the car, and the car air conditioner can be defogged by turning on it, because the car air conditioner has a dehumidification effect.

<> "In the process of using the vehicle, the most common thing for car owners is that the front windshield of the vehicle is easy to fog up. For example, the temperature difference between the inside of the car and the outside is relatively large, so once the people in the car exhale and encounter cold air, some water droplets will condense on the front windshield. However, the solution to fogging the front windshield of the car is also very simple.

A solution to windshield fogging.

1. When the front windshield is fogged, you can open the window for convection for a period of time to eliminate the fog on the car window, but in this case, it is often for the windshield, and the fog is not very large. And when opening the windows, you need to open the gaps of the same size on both sides of the windows.

2. The fog of the windshield can be eliminated by the method of external circulation, because the temperature difference of the air outside the car will be reduced a little bit in the process of convection, so that the fog will dissipate. This requires the owner to find the outer circulation button on the car and turn it on.

3. On the central control panel of the car, you can find a button painted with the front windshield to eliminate fogging, which is a fan-shaped button with three wavy arrows. After finding this button, as long as you press it, and then adjust the air outlet to align with the front windshield, basically about 2 to 3 minutes The fog will be eliminated naturally.

4. You can use the defogger, you need to spray the defogging agent evenly on the car cloth, and then wipe the front windshield with the car cloth, or directly spray it on the glass.

If you want the windshield not to fog, in fact, there are also small tricks, you can use the ratio of dish soap to water 1:6, wipe the windshield after dilution or take a small piece of soap bubble to soften it and apply it to the surface of the glass, after the completion needs to be wiped clean with a rag, which can basically be kept for a period of time without fogging.

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

1. You can open a gap between the windows on both sides, and the air inside and outside the car will be convection, and the fog will dissipate naturally.

2. The air conditioner can be defogged, turn on the fan and refrigeration switch in the car, let the cold air blow onto the glass, and the fog will disperse.

3. Turn on the hot air of the air conditioner, stop the vehicle on the side of the road, adjust the temperature to about 25 degrees, wait for the fog on the inside of the glass to dry out, and reduce the temperature a little. The windshield is made by sandwiching two pieces of glass together and separating them with a layer of PVC plastic, which makes the windshield have the properties of absorbing energy and absorbing shock.

1. Turn on the hot air conditioner. Yes, this trick is not unfamiliar 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. So if you can use the first method, it's still the first way.

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 wheel curved 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.

Workaround:

1. After diluting with 3m cleaning agent, wipe the inside of the windshield with a towel, and wait for it to dry naturally, so that the glass will not affect the line of sight due to the temperature difference and fogging.

2. It is very effective to open the skylight, or to open the cold air, using the refrigeration principle of the air conditioner, which can quickly eliminate the fog. Xiangkuan.

3. Turn the air conditioner to the warm air.

4. Defogging agent for removal.

Understand the causes of fogging on the front windshield to prevent and solve it:

First of all, the reason for the fogging outside the windshield is that the temperature difference between the inside and outside of the car is large, and the temperature in the cab is higher than that outside.

The water vapor in the car condenses on the glass and forms small water droplets, which adhere to the glass surface, causing the window to be white. Especially in places with high humidity, car windows are very prone to fogging.

If the front windshield is fogged, it can be defogged by the air conditioner defogging function, and you can also directly open the window for ventilation, and the fog will disappear. Another way is to turn on the cold air, and another way to remove the fog, which is to use a defogger to remove the glass mist water.

When the temperature inside the car is higher than the outside of the car. As the temperature rises, the humidity of the air is higher than that outside the car. However, when the moist air in the car air comes into contact with the windshield with a low temperature, the moisture in the air in the car will gradually precipitate moisture due to the cold, and gradually accumulate and eventually form a water mist attached to the glass.

Therefore, as long as there is an obvious temperature difference between the inside and outside of the car, or the humidity of the air in the car is too large, the phenomenon of fogging will occur.

In principle, the method of glass defogging is either to reduce the temperature difference or to reduce the humidity of the air in the car.

If there is fogging, it can be defogged by air conditioning. The method is also very simple, first turn on the hot air of the air conditioner, and then choose to turn on the defogging button, and the fog will disappear after a while. The good thing about this method is that it doesn't fog up the glass repeatedly.

In fact, there is another way to remove fog, and that is to open the cold air. Because everyone knows that if the fog encounters cold air, it will disappear. Therefore, after turning on the cold air for a while, the fog on the glass can be gone, so if you are afraid of the cold, wait until the fog is completely gone, and then turn on the hot air for a while, and you can do it.

The fog on the front windshield can be removed by the air defogging function, or you can open the window directly for ventilation and the fog will disappear. Another way is to turn on the cold air, and another way to remove the fog is to remove the glass mist using a defogger.

When the temperature inside the car is higher than the temperature outside the car. As the temperature rises, the humidity of the air body will be higher than that of the outside of the vehicle. However, when the moist air in the car comes into contact with the windshield with a low temperature, the water vapor air in the car will gradually precipitate moisture due to the cold, and gradually accumulate to form a water mist that adheres to the glass.

Therefore, as long as there is a significant temperature difference between the inside and outside of the car, or the air humidity in the car is too high, fogging will occur. In principle, the method of glass defogging is either to reduce the temperature difference in the car or to reduce the humidity of the air inside the car.

If fogging occurs, it can be adjusted by air. The method is also very simple. First turn on the air hot air and select the defogging button, and the fog in front of you will disappear in a while. The advantage of this method is that it does not fog up the glass repeatedly.

In fact, there is another way to remove fogging, and that is to turn on the cold air. Because we all know that if the fog meets the cold air, it will disappear. As a result, the fog on the glass can disappear after some time of cold air. If you are afraid of the cold, wait until the fog is completely away before turning on the hot air for a while.
