What to do if there is water mist outside the windshield, what to do if there is fog outside the win

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 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 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.

The following methods are available to solve the problem:

1. Open the window for convection, and when the fog is not very large, you can open a slit in the windows on both sides.

2. The air outside the car drives convection, the temperature difference is reduced, and the fog disappears.

3. Open the front windshield defogging button on the center console panel and adjust the alignment of each air outlet with the front windshield.

4. After the fog disappears, you can turn off the AC button of the air conditioner, continue to adjust the air volume a little smaller, and adjust the hot air to blow on the glass.

5. Spray the defogging agent evenly on a soft cloth, and then wipe the front windshield with a soft cloth, or spray it directly on the glass.

Reason: In summer, fog will only occur on rainy days, because the outside air humidity is high at that time, but the temperature is not low, and after the moist air meets the cool glass, the water vapor will condense into small water droplets, forming fog on the outside of the glass.

The principle is the same as that of fogging the inside of the glass in winter, which is due to the high humidity in the cabin and the cold glass forms fog. So if the air conditioner is turned on in the summer, the windshield will be cooler and more prone to fogging.

Therefore, if the outside of the glass is fogged, do not turn on the air conditioner and use cold air to blow the windshield, it will blow more and more seriously. This is different from defogging the inside of the glass in winter, which can be defogged with a cold wind on, except that the wind blows the glass dry.

The temperature of the cab is appropriately increased, so that the difference between the air temperature inside and outside the cab is not too large, and the windshield will not be fogged up without the condition of water vapor condensation.

For the situation that has fogged up, if it is serious, you can use the wiper to scrape it off first, and then blow a little hot air in the direction of the windshield, and the fog will dissipate immediately.

Cause: The outside of the windshield is fogged up because the air temperature in the car's cab is much cooler than outside the cab.

Other methods: Turn on the air conditioner. When the water temperature of the vehicle rises to a certain level, you can turn on the warm air conditioner of the front windshield, blow directly on the front windshield, and turn on the external circulation.

In this way, the temperature difference between the inside and outside of the front glass is reduced to achieve the effect of defogging. However, if the water temperature does not come up when the car is just started, the effect will be very poor.

Use dish soap to prevent fogging. This is a way to prevent car windows from fogging, that is, dilute the detergent used at home with 1:6 with water, and then wipe the car glass with a soft cloth dipped in detergent, and then wipe it with a dry cloth after the detergent is dry, which can ensure that the windows will no longer fog up for about 10 days.

You can also mix shampoo, shower gel, etc. and water at home in a ratio of about 1:10, pour it into a watering can, and spray the glass before driving to prevent the car glass from fogging.

Defogging and dehumidification methods:

1.Turn on the air conditioner (the AC indicator is on).

2.The ventilation mode is selected as: or .

3.The air circulation mode is selected as External circulation.

4.The blower speed is selected as the highest setting.

5.The temperature can be adjusted to a suitable position as needed (generally: cold air in spring and summer, warm air in autumn and winter).

6.The vents in the trunk also prevent fogging, so be careful to keep them clear.

The fogging is due to the poor sealing of the tuyere flap, and the air conditioning wind blows all the way to this position.

Wipe clean.

Defogger Defogger on the market ranges from tens of yuan to hundreds of yuan, and the ingredients are not much different, and the only difference may be durability. To use it, you only need to spray it evenly on the glass surface and wipe it clean with a dry towel.

If the wiper of the car is not clean, foggy or has abnormal noise, it will cause the driving vision to be affected, generally because of the rubber strip of the wiper There is a problem, which may be caused by long-term exposure to hardening or corrosion in rain and snow, so here there will be a wiper friction between the front windshield is not very uniform or there is a sealing system to produce a scraping area. In this case, it is recommended that you go directly to Jiajia ** or a certain treasure, a certain east to buy a pair of wipers that match the model of the car, come back or find a car wash brother to help install it, the effect is very obvious.
