How to defog the windshield of a car in winter?

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.

2. Air conditioning system.

For most car owners, the use of air conditioning system to defog is the most common. Nowadays, almost all cars on the market have air conditioning outlets under the front windshield, and you only need to select the air conditioner to the corresponding gear to use the air conditioning to defog. If you're in a hurry to get on the road, you can use a cold air, but in most cases we recommend using a warm air.

3. Defogging agent.

Auto parts city, supermarkets and many other places have special defogging agents, spraying the defogging agent to the inner surface of the car glass, and then wipe it clean, while removing the glass dirt, it can also form a protective film to prevent water vapor from condensing into a fog layer on the glass. The defogger can be sprayed and wiped for about ten days, and the easiest way is to mix it with detergent: detergent and water press 1:

10 of the mix, then use a clean, soft cloth dipped in it and apply it to the inside of the front and rear windshields, or pour it into a small watering can.

4. Defogging the rear windshield and exterior mirrors.

The cars sold on the market now basically have the "rear windshield electric heating" function, and the button position will be different, but the functions are the same. Turn on the "Rear Windshield Heating" switch, and it only takes a minute or so for the fog from the rear windshield to disappear. In dry climates, exterior mirrors are generally less prone to fogging.

1. Open the window for convection, open a gap between the windows on both sides to form a convection of the air inside and outside the car, the temperature difference will also be reduced, and the fog will slowly disappear;

2. Use the air conditioning system to defog, and select the air conditioner to the corresponding gear to use the air from the air conditioner to defog.

Summary. Dear, the defogging method of the windshield of the car in winter: open the window for convection, use the air conditioning system for defogging, use professional defogging agent, use detergent to prevent fogging, the common method is to open the window for convection.

In winter, the windshield is fogged, and the defogging methods are: 1. Press the defogging button of the front windshield; 2. Press the A C button to put the air conditioner in refrigeration mode; 3. Eliminate fog with the heating function of the air conditioner; 4. Use air convection; 5. Use defogging agent.

1. Heating function, after the engine is preheated for 5 to 10 minutes, when the water temperature reaches 80 to 90 degrees, the air conditioner can be turned on, and the temperature knob can be rotated to the red logo, the red logo refers to the warm air, adjust the air volume to the maximum, and turn on the front window defogging mode of the vehicle, and the fog will slowly dissipate.

2. Press the A C button, let the air conditioner be in refrigeration mode, turn up the air volume, blow the air outlet against the windshield, and the fog will slowly dissipate, this method is more suitable for no one in the car, because the refrigeration function will make the temperature in the car very low, which is a bit unbearable.

3. Turn on the air conditioner first, find the front window defogging button under the air conditioning control panel and press it, and adjust the wind speed to 18 degrees Celsius, and wait until 5 to 10 minutes later, the fog will be completely gone.

4. According to the principle of air convection to eliminate fog, open the window of the vehicle, do not need to open it all, open 1 8, this is to make the temperature difference between the car and the outside of the car smaller, so as to complete the purpose of eliminating fog, this method has certain limitations, is not suitable for vehicles in high-speed driving, or rain and snow weather.

5. Use a defogger to eliminate fog, buy a better quality defogger to spray on the windshield and windows, wait for 2 to 4 minutes and wipe it off with a dry paper towel, the defogging agent can prevent the generation of fog.

Causes of fogging outside the front windshield of the trolley:

The interior of the vehicle is hotter than the outside, causing a temperature difference between the inside and the outside, and the carbon dioxide that is caused by the breathing of the occupants in the vehicle contains carbon dioxide.

When this carbon dioxide encounters the cold glass on the outside of the vehicle, it condenses to form small water droplets. Generally, when the temperature inside the vehicle is higher than the temperature outside the car, it will lead to fogging, which is usually more common in winter.

In winter, the outside temperature is low and the inside of the car is high. When the temperature inside the car rises or the heater is turned on for a period of time, most of the windows are covered with fog. At this time, you only need to adjust the wind direction to the front windshield and let the warm air blow the front windshield for a minute or two to remove the long-term fogging.

If you want to quickly defog, you can turn on the air-outside circulation (turn off the warm air first, switch to the cooling air duct) or turn on AC cooling, and then adjust the wind direction to the front windshield to quickly defog, but this method cannot be defogged for a long time, and it will still fog up when the warm air is turned on again. Therefore, the first long-term defogging method is more recommended.

In addition, you can use special anti-fog products, special anti-fog products can be purchased in car stores or online, spraying once can be anti-fog for ten days and a half a month, the effect is very good, and the speed is also very fast.

At present, many models also have automatic air conditioning auto, and to turn on the automatic air conditioning defogging, you need to adjust the wind direction to the front windshield first, or directly use the defogging button. Automatic air conditioners, which we can think of as the "plus" version of manual air conditioners, have a "auto" button added to the appearance of manual air conditioners. When you set the temperature you want to need, and then press the "auto" button, at this time, the air conditioner will adjust the temperature in the car according to the temperature, humidity, ring number answer, etc., and adjust the environment in the car to the temperature calibrated by the driver and passengers as soon as possible, and adjust the constant temperature after reaching this temperature.

Millions of car purchase subsidies.

In winter, the front windshield of the car is defogged and teased: 1. Open the window; 2. Use defogging agent; 3. Turn on the air conditioner heater; 4. Turn on the defogging function of the car; 5. Apply dish soap mixed with water or soapy water to the car window; 6. Put a dehumidification box in the car; 7. Wipe with a towel; 8. Turn on the refrigeration switch by increasing the air volume appropriately. The causes of fogging in the front windshield of a car in winter are:

The temperature difference between the inside and outside of the car, the temperature in the cab is high and wide, and the temperature is staring at the outside, causing the moisture in the cab to condense on the inner windshield and form fog. The methods to prevent fogging in the front windshield of the car are: 1. Use special defogging products before driving the car; 2. Use the refrigeration and dehumidification function of air conditioning to reduce air humidity.

There are the following solutions to fogging outside the car window:

1. Kaishi shouts window defogging: adjust the car glass button to leave a silver dust gap in the window, reduce the temperature difference and avoid the car fog production. In this way, the air inside and outside the car forms a convection, the temperature difference decreases, and the fog will slowly disappear;

The limitations of opening windows to remove fog are very obvious, if the fog in the car is large, or it is rain and snow weather, or driving on the highway, it is not suitable to open the window to remove fog, and opening the window will also reduce the temperature in the car;

2. You can use a clean rag to wipe the fog on the car window;

3. Air conditioning defogging: you can use the vehicle air conditioning system to defog, at present, basically all cars on the market have air conditioning outlets under the front windshield, just select the air conditioning to the corresponding gear;

In winter, the temperature difference between the inside and outside of the car is too large, and it is cold outside and warm inside, causing the windows to fog up. At this time, you can turn on the AC refrigeration switch in the car to let the cold air blow on the front windshield, and the fog will disappear soon;

4. Detergent blending method is sprayed on the outside of the car window to defog: use soap and dish soap mixed with water to spray on the glass, and form a layer of oil film on the surface of the glass to achieve the effect of no fogging. However, this oil film will cause the front windshield to form a dazzling effect at night, affecting driving safety;

5. Defogging with wipers: The fog outside the window is generally caused by rainwater condensation, and it is okay to scrape with a wiper, but if it is a frost in winter, it should be wiped with water, not with a wiper to avoid damaging the wiper;

Fourth, carry a frank cavity defogging method, and make it easy for you to believe that the branch will fog up the car in different situations, which is simple and useful.

When driving the car, we can turn on an internal circulation hot air, so that we can deal with this problem very well.

The air conditioner should be turned on for defogging, and the air conditioner should also be turned on for defogging, these are all methods of defogging, and the effect is also very obvious.

At this time, it is necessary to open the inner circulation in the car, which can purify the air, and then enter the fog into the glass, or some vehicles can also open the defogger to effectively remove the fog.

There are three main ways to defog the front windshield, the first is to intermittently open the window to allow the temperature inside and outside the car to balance, and the fog will disappear automatically soon. The second is the air conditioner warm air defogging, which can not only dry the fog on the windshield, but also allow fresh air from the outside to enter the car, and you won't feel too stuffy when sitting inside. The third is the automotive glass defogger, which is now very good, and it can be sprayed for about a week.

You can use a dry towel to wipe it off, or you can turn on the heater to warm it up and remove the fog, which is a safe way to travel.

The easiest way is to open the window to remove the fog, you can also use the cold air of the air conditioner to remove the fog, of course, you can also remove the fog manually, find a clean rag to wipe it clean.

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.
