What to do if the front windshield of your car is fogged

When the car starts in winter, the windshield is always easy to fog up, which affects the line of sight and has a great impact on the line of sight. Moreover, it is particularly difficult to eliminate, and it takes a long time to complete the defogging after opening the air. What do we do when the front windshield of a car is foggy?

Air conditioned cold 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. The problem with this method, however, is that it can be very cold in the car, especially in late autumn. The strange thing is that if the weather turns cold again, the person who gets cold in the car will not curse you to death.

What's more, once the air cold air is turned off, fog will immediately form, which is very annoying, not to mention the problem of fuel consumption.

Warm air air conditioning.

If you want your car to be completely fog-free, you should choose on the air and hot air blowing 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. This method is slow to remove fogging, but the effect is indeed the best and most aggressive in rainy and snowy weather.

When the humidity in the car is reduced and the air is dry, it is possible to keep the windows fog-free for a long time, and it is also suitable for the cold autumn, at least the interior of the car will be warm and pleasant. The disadvantage is that this method is not suitable for driving, because the warm air in the early stage will increase the temperature difference in front of the windshield, causing fog to cover the entire glass. Only by waiting patiently for it to dry completely can the windows be clear and clear before driving.

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 windows. 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 glass will not continue to produce fog.

However, whether this method is harmful to the human body remains to be examined. 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 outside of the front windshield is fogged up, and the windshield wipers can be used to scrape the fog away and see the outside.

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 up the windows, which will affect the driver's vision and pose a safety hazard to the vehicle. So, what to do about fogging up your 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 dissipate. 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 feel cold in the winter, so you might want to give it a try.

You can also get 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. Spray a little defogging agent on the car glass, and then wipe it clean, you can remove the dirt and stains on the glass. While polishing the glass, 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.

The reason for the fogging of the windshield is very simple, it is because of "cold on the outside and hot on the inside". It can be solved like this:

1. After diluting with 3M cleaning agent, wipe the inside of the windshield with a towel and wait for it to dry naturally. The glass will not be fogged up due to the temperature difference and affect the view.

2. You can open the skylight to have a certain effect, or you can open the cold air, using the refrigeration principle of the air conditioner, you can quickly eliminate the fog, 3, 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, causing the water vapor in the cab to condense on the inner windshield to form fog.

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.

This phenomenon is mostly seen in the humid rainy season, such as the environment of internal heat and external cold, and the carbon dioxide exhaled by the occupants after getting into the car will also condense into water vapor and adhere to the windows when they encounter cold glass, causing the front windshield to blur their vision, so defogging is essential.

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.

The reason for the fogging of the front windshield of the car is "internal heat and external cold", and when the temperature difference between the inside and outside of the car is large, the occupants in the car exhale'Water vapor condenses into water vapor when it encounters cold glass. So what do you do if you know that the front windshield of a car is fogged? The following is what to do if the front windshield of the car is fogged out by me for everyone, for reference only, I hope it can help you.

The most primitive method: wipe with a dry cloth or paper towel

Pros: Immediate.

Disadvantages: laborious, unsafe, leave marks after wiping.

The most primitive method is to wipe the glass directly with a dry cloth. This kind of scene must have been seen by many citizens: the old drivers always keep a towel and wipe the glass vigorously when they stop at a red light.

The disadvantage of this method is that it is more laborious, and it will leave marks on the glass after wiping, and it will quickly fog up again. If you wipe while driving, it is easy to cause accidents.

The most convenient way: blow with hot air

Pros: No distractions.

Disadvantages: Slow onset, the rest of the windows are still fogged.

The second method is to blow directly with hot air. However, this method works relatively slowly, and when the hot air is turned on in the middle of the vehicle, the fog on the front windshield becomes larger and larger, and it will take about ten minutes for the glass to gradually become clear. Netizen "Park Opportunity" suggested that the hot air should be turned on immediately after the car is heated, and the "high temperature" above 25 should be used to blow first, and then slowly lower the temperature after the fog disappears to control it at about 22.

The most creative way: Dish soap with a dry cloth to wipe

Advantages: Good preventive effect.

Disadvantages: To be dealt with in advance.

For the treatment of fogging in the front windshield of the car, you can refer to the above operation to try it. Especially when driving on the road, fogging up the front windshield of a car is a very dangerous thing.
