How to remove the fogging of the interior glass of the car, how to remove the fogging of the car gla

Automobile glass defogging method uses air conditioning system, window opening convection, and detergent anti-fogging.

1. Use air conditioning system

It is common practice to use the air conditioner's defogging function. Turn the air volume up appropriately, and turn on the refrigeration switch at the same time, then the cold air will blow on the glass, and the fog will soon disperse, and the effect is very fast and direct. One of the biggest drawbacks of this method is that the occupants of the car may feel very cold, and blowing for a few minutes may turn off the air conditioner, and after a while, the fog will start to hang on the glass again, and the air conditioner will be turned on again.

In addition, hot air defogging is also possible. Turn on the hot air without adding extra energy consumption and driving comfortably. In fact, the effect of blowing glass with hot air is better than blowing with cold air, but the process is much slower than that of air conditioning.

When it is first opened, it will indeed make the fog on the inside of the glass bigger, this is because the temperature difference between the inside and outside is greater, and after the hot air dries the moisture in the car, the glass will become translucent, and the process will be good in a few minutes, because the car is dry, and there will be no fogging for a long time. Therefore, it is recommended to use hot air to defog first when parked, and then you can keep it fresh all the time when you go on the road. In addition, opening the external circulation during driving can also prevent fogging to a certain extent.

In addition to the front windshield, the side windows can also fog up, and the fog on the front side windows can affect the driver's view of the rearview mirror. Nowadays, cars have an air outlet that blows the front side window separately, but it is generally very small, if you feel that the effect is not obvious, we can close the two ** air outlets, so that the air outlets on both sides can get a larger air outlet.

Summary: The air conditioner defogging effect is very fast, but the car will be colder; The hot air effect is slightly slower, if the hot air is defogged before driving, it will be very refreshing and warm along the way.

2. Open windows for convection

If the fog is not large, you can open a gap in the windows on both sides to allow the air in the car to be convection, and the temperature inside the car will slowly approach the temperature outside the car, and the fog will dissipate. The advantage is that it can achieve the effect of turning on the air conditioner without increasing fuel consumption, but this method is not suitable for all situations, such as in the cold winter and when it rains.

Summary: This is a good method when it is not raining and the temperature is acceptable, but the disadvantage is that it is not suitable for use when running at high speeds.

3. Detergent anti-fogging

The method of blending "anti-fogging agents" to prevent fogging has been well known to many people. The ratio of washing spirit to water is about 1:10, and then apply it to the inside of the front and rear windshields with absorbent cotton or a clean and soft cloth.

Allow to dry before wiping off any remaining watermarks left on the inside of the glass. It will work better with an air conditioner.

Summary of tips: It can be effective in 10-15 days, it costs very little, but the operation process is more cumbersome.

Wipe method. The so-called wiping method, that is, scrubbing the car glass with a towel, is only very limited by this method, such as some thicker icing, even if it is scrubbed with a towel, it may not work;

2. Heating method. It means that before using the car the next day, start the vehicle to do a hot car operation, and then turn on the vehicle heater system after the engine water temperature rises, so as to melt the frost on the glass. Although the heating method has a certain effect, the disadvantages are also obvious, such as taking a long time, and will lead to carbon deposits in the vehicle, and will also increase fuel consumption.

3. Heat dissipation method. For the concept of heat dissipation method, in fact, it means that after the car is used up the day before, do not rush to close the door first, so that the air inside and outside the car can be kept circulating, so as to reduce the residual heat in the car and avoid serious icing problems on the windshield after the temperature drops at night;

Car windshield de-icing tricks.

The so-called windshield de-icing trick is also the most common method used by veteran drivers, which not only keeps the windshield clean, but also very warm. This trick is the covering method, which uses a special car glass freeze cover to cover the windshield of the vehicle, so as to prevent the glass from being easy to freeze.

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.

There are the following methods to remove: 1. Air conditioning defogging; 2. Use defogging agent; 3. Open windows to remove fogging.

1. Air conditioning cavity cleaning and defogging;

When the glass is foggy, turn on the air conditioner to blow the glass, and the air outlet under the front windshield will blow the air against the large air volume of the glass, quickly blowing away the moisture, and at the same time, it can also reduce the temperature difference between the inside and outside of the glass, which has the effect of eliminating fog.

2. Use defogging agent;

There are a lot of defogging products nowadays, spray it on the windshield, wipe it clean with a rag, and spread it evenly. While removing the glass dirt, it can also form a thin layer of transparent protective film on the glass, which can prevent the condensation of water vapor on the glass and form a fog layer, which can really be effectively maintained for about a week or two, which is more convenient.

3. Open windows to remove fogging.

This kind of defogging is to open the windows on both sides of the car to allow the air to balance the convection, so that the temperature inside and outside the car is close, and the fog will disappear. Socks are made.

But this is suitable for use when the fog is not very large and the temperature is not very low. Generally, it is not recommended to use it when it rains and the temperature is low, so it is not recommended when driving at high speeds.
