Car windows are easy to fog up in rainy days, how to solve it

Although many car supply stores currently have special defogging water for cars, it is indeed a bit expensive and outrageous, and it is really a bit too luxurious to use it.

When catching up with rain and snow, there is no need to use cold air or internal circulation air to defog, as long as the defogging water is prepared and applied to the windshield before this. The preparation method of defogging water is extremely simple, now almost every family has something like washing spirit, which is a necessary cleaning supplies in the kitchen, you just need to find a small utensil, squeeze in a little washing spirit, mix it with water in a ratio of about 1:10, and then use absorbent cotton or soft cloth dipped in it to apply it to the inside of the front and rear windshield (including the window glass at the rearview mirror), and then wipe the residual fibers left on the windshield with suede or a soft dry cloth after drying, and so on, you will go on the road steadily. No matter how heavy it rains outside, even if the windows are closed tightly, even if more than a dozen people are panting inside without fogging, applying it once can ensure that it will work when it rains for several days in a row, and the glass is very bright.

If you catch up with the weather with too much humidity, when the temperature difference between the inside and outside of the car is large, you can slightly increase the proportion of washing spirit.

In addition, many things related to household washing can also be used as substitutes, and they can achieve a very good defogging effect, such as melon and fruit cleaning liquid, hand sanitizer, soapy water, laundry detergent (of course, it must be dissolved), bath liquid, shampoo and so on. It is recommended to have the most simple and easy-to-use detergent at your fingertips. If you are lazy, you want to be simpler and more trouble-free, you can also use more cans in a small watering can at a time, spray as you like, just don't spray too much at a time to make it flow everywhere, so that even the glass is free, and when it comes to car washing, its existence can also directly play a role in cleaning.

The method is as follows: 1) Use special defogging products.

In many markets and places such as auto parts cities, there will be some stalls selling special products for defogging and anti-fogging, such as defogging agents or fog towels. This kind of defogging agent is sprayed on the inner surface of automobile glass, and wiped clean, while removing 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, spraying can prevent fogging for ten days - half a month.

2) Open windows for convection.

If the fog is not heavy, you can open a gap in the windows on both sides (you can't do this when it's raining) so that the air inside the car will be convection, and the temperature inside the car will gradually 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.

3) with air conditioning system.

The usual practice is to turn on the fan and refrigeration switch in the car, so that the cold air blows on the glass and the fog will soon disperse, and the effect is quick and direct. This is because the cold air blows onto the glass, forming a "cold film" on the surface of the glass, preventing carbon dioxide from condensing on the glass and having a defogging effect.

Because the temperature difference between the inside and outside of the car is too large.

The most effective way to dehaze is to add half of the washing liquid to half of the water, shake well, and wipe it with a cloth in the area prone to fogging.

The ratio of the two things can be flexibly controlled, and if there is more water, the maintenance time is short, and the advantage is that it can be used immediately without affecting the line of sight.

If there is less water, keep it for a long time, then wipe it, pay attention to a few hours before driving, the concentration of washing liquid is large, and it will affect the sight a little when it is not dry.

While saving fuel, there is no need to blow air conditioning in the winter.

You can use radish or alcohol to wipe the glass, so it is not easy to fog up

The windshield of a car looks very smooth, but it actually has very dense concave and convex holes. If you want the windows to not fog up, you can completely solve it by wiping it with dish soap.

1.You can turn on the air conditioner to hot air before the car starts, and blow the front windshield directly for 3 minutes, which can fundamentally avoid fogging the glass;

2. Turn on the cold air of the car air conditioner and turn the air outlet to the windshield in front of the car, so that the glass fogging can be quickly removed;

3. Turn on the dehumidification mode of the air conditioner to achieve a relatively fast defogging effect;

4. The owner can turn on the defogging function of the air conditioner, and the fog will dissipate quickly.

The main reason for the fogging of car window glass is that the temperature difference between the inside and outside of the glass is too large, and the other is that there is too much moisture. In winter, the warm air conditioner is turned on. In addition, when the weather is wet on a rainy day, both factors are satisfied, and it is easy to fog up.

If you don't want the glass to fog up, it's best to keep the temperature inside and outside the car consistent.

1. Rational use of air conditioning system.

2. Use special anti-fog products.

3. Open the window to convection of hot and cold air.

4. Wipe with dish soap and dry cloth.

5. Defogging of the heating wire of the rear windshield.

How to solve the fogging of the car window on a rainy day? Glass fogging after rainy days can be dealt with by the following methods: 1. Air conditioning refrigeration defogging:

There are two main causes of fogging of car window glass: low temperature and high humidity in the air. Air conditioning can be used to remove fog from the front windshield, but if the air conditioning in the car is too humid, then the effect will not be too obvious, and the windows can be opened slightly to quickly reduce the humidity in the car.

2. Open the window for convection and defogging: open the window for convection of cold and hot air, the fog is not large, and the windows on both sides can be opened a gap, so that the air in the car is convection, and the temperature in the car is slowly close to the temperature outside the car, and the fog will disperse. The advantage is that it can achieve the effect of turning on the air conditioner without increasing fuel consumption, such as in the cold winter and rain, it is recommended to take intermittent opening and closing of the window.

This method is not suitable when fogging is severe. 3. Anti-fogging agent: The use of glass anti-fogging agent can form a transparent hydrophobic ion film on the surface of the glass to prevent the condensation of water droplets and fog.

4. Anti-fog towel: When fogging, wipe it with an anti-fog towel, it will no longer fog up, and the effect of anti-fog towel and defogging agent is exactly the same. 5. Detergent anti-fogging

Blend with detergent. The ratio of washing spirit to water is about 1:10, and then use absorbent cotton or a clean and soft cloth dipped in it to apply it to the inside of the front and rear windshields, or you can use shampoo, shower gel, etc. at home and water at 1:

The ratio of about 10 is good, pour it in the watering can, and spray it on the glass before driving to prevent the car glass from fogging. Window fogging can be solved in the following three ways: 1. Automobile defogging; 2. Soap method; 3. Use the car defogging button.

The solutions to fogging of rainy windows include window opening convection, air conditioning defogging, detergent anti-fogging, glass anti-fogging agent and rain eyebrows.

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. The principle of this method is the same as turning on the air conditioner for cold air, but it does not increase fuel consumption. At the same time, it should be noted that the opening of the window should not be too small because of the rain, and the opening amplitude of the window should be adjusted according to the size of the rain to be effective.

2. Air conditioning defogging

This method is the most labor-saving and fast, find the front window defogging switch, then adjust the wind speed to the maximum, turn on the A C switch, and then adjust the temperature to the lowest, and the fog on the glass will be gone after a while. In addition, the rear windshield and exterior mirrors of some models are equipped with electric heating, which can be used to eliminate fogging in about a minute after the switch is turned on.

3. Detergent anti-fogging

This is a rainy day defogging method that many people will take, and the operation is simple. Car windows are sprayed with detergent defogging, the cost is very low, the operation is convenient, and the soap method and dish soap method are commonly used.

1. Soap method

Moisten the soap with water to soften it, then apply it evenly to the entire surface of the glass (be sure to be even), and when the soap on the glass is dry, remove it with a paper towel or newspaper. Be careful not to use a towel, as it is easy to leave fine crumbs with a towel. However, this method has a small disadvantage of defogging in rainy days, that is, a small amount of soap will remain on the glass, but it will not affect the overall vision.

2. Detergent method

Find an empty bottle, fill it with water and dish soap in a 9:1 ratio, spray it on the front windshield and two side windshields when it fogs up in the summer rain, and wipe it off with a soft paper towel to prevent fogging.

The principle of anti-fogging is: the detergent can damage the attraction between water molecules and reduce its surface tension, so that the water molecules are evenly dispersed on the surface of the glass treated with anti-fogging, and are attached in the form of a water film.

Fourth, glass anti-fogging agent and rain eyebrows

Spray a little defogging agent on the car glass window and then wipe it clean, you can form a thin transparent protective film on the glass, which can effectively prevent the car window from fogging, and the effective time is quite long, basically it is no problem to keep it for a day or two.

The easiest thing is to install "rain eyebrows" on the rearview mirror, but this is only effective when it rains lightly, and the effect is limited if it is in windy and rainy weather.

The correct way to defog a car on a rainy day is to use a defogger, air conditioner defogging, and air convection defogging.

1. Air conditioner defogging: Turn on the front window defogging mode, adjust the wind speed to the maximum, turn on the AC switch, and then adjust the temperature to the lowest, and the fog on the glass will be eliminated after a while. In addition, the rear windshield and exterior mirrors of some models are electrically heated, which can be used to eliminate fogging in about a minute after the switch is turned on.

2. Defogging agent: When using, you only need to spray it evenly on the surface of the glass, and then wipe it clean with a dry towel. The principle is to use surfactants to retain a certain protective film on the surface of the glass, change the surface tension of water molecules, and make the fog beads condense into large water droplets, so as not to block the line of sight.

Other glass in the car can also be used, especially exterior mirrors.

3. Air convection: After opening the window, you can increase air convection, reduce the temperature difference between inside and outside the car, and weaken the conditions for fog formation.

The principle of defogging of automobile air conditioners

1. The physical principle of automobile cold air: after the liquid refrigerant absorbs the heat of the object that is cooled in the evaporator, it vaporizes into low-temperature and low-pressure steam, which is sucked in by the compressor and compressed into high-pressure and high-temperature steam, which is discharged into the condenser.

2. The physical principle of hot air defogging: when the gas containing the fog foam flows through the mist eliminator at a certain speed, because of the inertia of the gas, the liquid droplets gathered because of the collision between the fog and the wave plate are very large, and the gravity caused by the droplets exceeds the combined force of the gas lift and the surface tension of the liquid, and the droplets are separated from the surface of the wave plate.

3. In the condenser, it releases heat into the cooling medium (water or air), condenses into a high-pressure liquid, throttles into a low-pressure low-temperature refrigerant through the throttle valve, and then absorbs heat and vaporizes in the secondary evaporation device, which reaches the purpose of circulating refrigeration. In this way, the refrigerant completes the cold cycle through four general processes of compression, condensation, throttling and evaporation in the system.

Summary. 1.Turn on the air conditioner switch and blow the air outlet against the glass.

2.Turn on the heater switch, and the air outlet blows air on the windows, but this defogging speed is slow, but the effect is good. 3.

It is also possible to open the windows a little to allow convection between the outside air and the gas inside the car.

1.Turn on the air conditioner switch and blow the air outlet against the glass. 2.

Turn on the heater switch, and the air outlet blows on the window, but the defogging speed is slow, but the effect is not combustible and wide. 3.A slight slit in the window of the car allows the air trapped outside to convex the gas inside the car.

Can you tell us more about that?

Fogging in the car is caused by the air in the car encountering the cold air bridge on the glass early, and becoming a liquid attached to the glass before the liquefaction hole disappears, so as long as the window is kept clear and the temperature inside and outside the same will not fog up.

It is normal to encounter fog in the car on a rainy day. It is also something that every driver can encounter when we drive, and the new drivers must not be nervous at this time. Then the fastest and fastest way is to turn on the cold air of the air conditioner.

Because we all know that if we turn on the refrigeration function of the air conditioner, plus the external circulation, it should take less than a minute for the fog on the glass to be blown clean. Therefore, new drivers must pay attention to this kind of problem. I believe that many old drivers will definitely refute, if it is in autumn or winter when it is very cold, then what should be done?

If we fog up while driving in the winter, we will definitely be scolded to death by the people in the car if we turn on the air conditioner. And if you turn the air conditioner on and off all the time, it will be a waste of oil.

And then a small way is that we can use the hot air of the air conditioner or heat. If you want the car to be completely free of fog, you should choose the heating of the air conditioner to blow the windshield. Because this defogging effect will be better.

We all know that the principle is to use warm air to dry the water molecules in front of the windshield. But we must be aware when doing this, such a problem is that small water droplets will form on the glass. The recommended method is that it takes a long time, and it is the best and most effective in rainy and snowy days, so novice drivers can try this method.

Another more economical way is to open the windows and sunroof, so that the air in the car and the outside air have a convection effect, which can reduce the temperature in the car. But this method is also the fastest way to remove fogging, first, it is more economical, no need to turn on the air conditioner to remove fog, but this method is not used for winter, because the effect is not obvious, the key is that it is particularly cold. Another small way is to buy some defogging agent on a certain treasure, which is also very effective.

**Generally between 10 yuan and 200 yuan, because of different brands, so there will be different**Oh, this is still according to your own situation to choose. There is another option that is more unpopular, we can prepare some anti-fog towels, and wipe them manually when there is fog, but this is the most inconvenient and unsafe one when we drive in the middle of the road.
