With the onset of cold weather, many motorists have to deal with such a phenomenon as fogging of windows in the car... This phenomenon is not only unpleasant in terms of comfort, but also poses a great danger to drivers in the form of limited visibility. In addition, drivers constantly have to be distracted in order to wipe the fogged-up windows, which is strictly forbidden to do while driving.
Increased humidity in the cabin, which is the main reason for which fogging of glasses, is also fraught with the occurrence of corrosion and the appearance of unpleasant odors due to the formation of mold, fungi and harmful bacteria, for which a humid environment is an ideal breeding ground.
Today I will try to figure out and understand why glass sweats and how to avoid fogging up car windows.
First of all, I propose to talk about the reason why the windows in the car sweat.
The main reason why the windows fog up is condensation, in other words, moisture that settles in the form of the smallest particles of water in the coldest parts of the cabin, which, as you know, are car windows. Moisture is formed as a result of hot breathing of a person, therefore, the more passengers there are in the cabin, the higher the humidity in it, and the stronger the fogging of the windows.
In addition to the exhalation of a person, sources of moisture in the cabin can be damp weather outside the window, as well as wet shoes or car mats, which absorb a large amount of moisture from the shoes. The source of moisture in a car is often a car stove, which operates regularly during the cold season. Moisture ingress occurs through the oven hole, designed for air intake, it is located in the upper part of the hood, near the plastic protection. Snow that accumulates there during the melting from a warm engine increases the level of humidity in the car's interior.
About, why do glasses sweat you already know, now I propose to talk about how to eliminate fogging of windows, that is, about ways to combat fogging of windows in a car.
To get rid of the fogging of the windows, you need to regularly take care of the interior and adhere to simple rules, which we will now talk about.
The salon must be kept in constant cleanliness, this is especially important in rainy weather or in winter during a thaw. You should regularly ventilate the interior and make sure that the carpets are not wet, and dry them regularly. Before getting into the car, tap or sweep your shoes, and in rainy times, try to keep your shoes dry (avoid getting wet, or change). Alternatively, you can choose which is easier to care for, and if moisture appears, it can be carefully poured out. The shape of the rubber mats does not allow moisture to go beyond the sides, so the moisture from the shoes does not go anywhere.
If you notice that snow has accumulated on the hood grille, do not be too lazy to shake it off, otherwise the snow in the form of moisture will fall into the passenger compartment when the stove is turned on. Dry and ventilate the cabin from time to time, to do this, turn on the air circulation in the cabin, regularly clean the car windows from ice. In winter, fill the "anti-freeze" into the windscreen washer tank, the liquid must contain alcohol, which prevents freezing.
When constantly sweat glass in the car, make it a rule to properly ventilate and warm up the car interior before driving. Warm up all the glasses first, and do not create sudden changes in temperature; if the windows in the car are frozen, warm them up gradually. Do not forget also about such important elements as: air conditioner, stove - all these elements must be in good working order and clean.
- an excellent solution to the problem of fogging the windows in the cabin, it dries the air perfectly and keeps the optimum temperature. If the car is not equipped with air conditioning, then fresh air or a stove will help to defeat the fogging of the windows, and it is better if they work in tandem. That is, with a working stove, turn on the air circulation from the street.
For proper operation of the blowing, direct the flow regulators (deflectors) to the most misted areas and move the circulation lever to the extreme left position.
Alternatively, you can consider a method that allows you to partially "overcome" the fogging of the windows. It provides a small upgrade to the luggage compartment duct by cutting small holes in the side trims of the luggage compartment. In the resulting "windows" it is necessary to install plastic grilles (y), due to which the outflow of air will significantly increase. After such a small upgrade, air ventilation in the cabin will be more efficient, after such a procedure, much less sweat glass in the car.
The next option is the use of anti-fogging agents, which prevent moisture from collecting and effectively fight against condensation. Anti-fogging agents are most often of two types:
- In the form of a special liquid that covers the glass with a transparent film that does not allow moisture to accumulate on the windows.
- In the form of a liquid that repels moisture.
- Anti-fogging mastic. They are the most effective, but at the same time the most expensive among the above. The principle of their operation is based on similar principles - the glasses are covered with this compound and prevent the glasses from fogging up and getting wet. Most importantly, one treatment is enough for several "wet" rides in wet weather.
Anti-fogging agents are applied exclusively to a dry, clean surface, but if you apply liquid to a fogged window, there will be no effect, and the money will be wasted.
In winter, it is recommended to use "Antiled" and "Non-freezing" products in the cabin, they help to fight the accumulation of moisture on the glass and provide excellent visibility. These products contain alcohol in their composition, which prevents the formation of moisture and the accumulation of dirt, allowing you to keep the glass clean. The special composition allows for a long time to forget about the fogging of glass, as well as ice on the windows, even at -25 °. Special products work for at least 72 hours after application. the liquid does not affect the transparency of the glass and is excellent at fighting moisture.
That's all for today, I hope my article will help you solve the issue. fogging of windows in the car.
How to be and what to do.
Every driver at least once in his life has encountered such an unpleasant phenomenon as fogging of windows. In such a situation, windows do not just create discomfort, they can become a serious problem, because perspiration significantly limits visibility. Why is this happening? What to do in such a situation? Here are some tips for doing this.
Reasons for fogging windows
It is important to understand why this is happening.
Car windows can fog up for several reasons. Each of them is based on the process of steam formation. In the cold season, the glass of a car can become covered with condensation due to the temperature difference in the car interior and on the street. In addition, glass fogging occurs during rain, in damp weather. A defective or dirty cabin filter, its infrequent or untimely cleaning, can also cause condensation to form.
If an oily film begins to appear on the windows of the car, this is a dangerous signal indicating a leak in the battery.
General solutions to the problem
There is nothing difficult in eliminating perspiration.
1. First of all, it is necessary to correct the settings of the car's climate system. A directed stream of warm air can solve this problem in just a few minutes.
Turning on the stove most often does not work unless it is used in conjunction with the ventilation system.
2. You can resort to the use of special tools, which today are present in sufficient quantity and range on the market. Most of these "helpers" are readily available.
3. Drying and preventive ventilation of the passenger compartment will make a huge contribution to the fight against fogging of windows. Sometimes it is enough just to open the vents for this.
What to do when it rains
The main thing is to keep it dry.
1. First of all, the side windows should be slightly opened immediately after starting the movement. This will improve the air circulation in the passenger compartment. Do not forget about preventive drying and ventilation of the passenger compartment after the trip.
2. Do not leave wet things in the cabin, such as an umbrella.
3. Timely change and clean the pollen filter, eliminate malfunctions of the valve or sensor that regulates the operation of the dampers.
The windows fog up in winter, what to do
It is not difficult to remove fumes in winter.
In such a situation, it is best to use a special composition. Its regular use should completely eliminate the problem. However, you can try to solve the issue with improvised means. First of all, you can wipe the windows with a rag with shaving foam. You can do the same with lemon or soap. Finally, you can spread the newspaper or bags of salt in the cabin.
Car fogging is a problem that most often occurs during the off-season. On the street there is often high humidity, with shoes, a lot of moisture is brought into the salon from the umbrellas. And then, when you turn on the stove, moisture actively evaporates and condenses on cold glasses.
Cabin filter
Generally speaking, in a car in which everything is working properly, moisture is removed and the glass does not sweat, unless you boil the kettle inside. So, if the problem of fogging glasses is relevant to you, look for the reason.
The most common is the cabin filter. All drivers regularly change the oil filter and air filter, but for some reason they forget about the cabin filter. Meanwhile, it needs to be changed about once every 15-20 thousand kilometers. Most often it is changed from the glove compartment. Look at his condition. If it is dirty, then perhaps replacing it alone will solve the problem.
Door gutters
Another reason for increased moisture is clogged door gutters. There are drainage holes in the doors under the seals. After years of operation, they become clogged with dirt, small debris, and the water from the doors does not go anywhere. As a result, you have not only increased humidity in the cabin, but also accelerated corrosion of the bottom of the doors. Locate the drain holes and clean them with fine, stiff wire. Sometimes, already in the process of cleaning, water is poured out of there and the problem with the fogged glasses goes away.
Air vents clogged with leaves and dirt can also cause poor ventilation. In some car models, they are located between the windshield and the engine compartment. There, in the fall, foliage just accumulates, and in winter, debris and snow. There are also ventilation holes in the trunk. They are hidden behind the skin, but they work nonetheless. And if you passed them over or blocked them with something, excess moisture will no longer go away.
Air recirculation and air conditioning
Very often the windows sweat due to the fact that the driver does not use the air conditioning system correctly. Check if your cabin air recirculation mode is on. If it is on, then turn it off and turn on the mode of air intake from the street. In general, the air conditioner helps very well to dry the interior and remove excess moisture. If you have it in your car, turn it on (you can turn it on safely and without fear, even in case of frost) at least for a while.
The last argument
If none of the above helps, use a moisture-wicking pad. They are sold in car dealerships and car markets, and can be ordered on Aliexpress. Inside the pad is a desiccant, like the kind that goes inside the shoe in small paper bags. This filler will absorb excess moisture and become heavy and damp.
To dry it, you need to take the pillow home and put it on the battery. Or just put it in the microwave for a few minutes and turn it on. Then it can be used again.
In general, in order to avoid the accumulation of excess moisture in the cabin - and it accumulates most often on rugs or under rugs - in autumn and winter it is better to use rubber mats rather than pile mats. And under them it is still good to put special "car diapers" that absorb moisture. Well, or you can do it the old fashioned way - put a newspaper under the rugs in several layers and change it periodically when it gets wet. Newsprint is excellent at absorbing moisture.
You can also buy special auto chemistry for glass fogging, but many advise to rub the glass with shaving foam. They say the effect is the same.

Windscreen fogging is a real problem, especially for a novice driver. So why does the glass sweat? Due to the difference in temperature inside the car and outside. It is warmer inside the cabin than outside, because moisture condenses on colder glass.
One of the reasons for moisture condensation is people in the cabin. The air exhaled by passengers is abundantly saturated with moisture. Therefore, a trip in a large company often requires the driver to constantly adjust the airflow and adjust the climate system.
Another reason for fogging is. After poor-quality repairs, the air ducts from the climate system unit to the deflectors may not be installed correctly. Air conditioning system drain holes can also be damaged. As a result, condensation simply has nowhere to go, and it most likely enters the passenger compartment. And the more moisture inside the car, the more the glass sweats.
Finally, the windows can sweat due to the fact that the passenger is in the car, as they say, "after yesterday." As a result, a person's sweating increases and the pulse quickens. The exhaled air contains more moisture. And the car interior is a closed space, and here the air saturation with vapors occurs very quickly. By the way, the "fog" on the windows very much attracts the attention of the traffic police, who use it to identify drunk drivers.
How to fight?
The easiest way to combat fogging is to keep the air dry. To do this, turn on the air conditioner. It dries air very quickly. You can also change the air circulation in the passenger compartment by directing the ventilation deflectors to the glass, thereby heating the latter. Monitor your condition. If it is clogged or damp, it must be replaced, otherwise the glasses will perspire regularly.
Car chemistry manufacturers produce a variety of anti-fogging products: aerosols, wipes, liquids. These products form the thinnest film on the glass, which prevents moisture from remaining on the glass. All formulations are applied to a dry surface, otherwise they will not work.
There are also cheap anti-fog "glasses". Ten parts of alcohol are added to one share of glycerin and applied to glass. The old-fashioned method has a significant disadvantage. Such a composition leaves a greasy layer on the surface. At night, stains greatly impair visibility, glare appears.
Some even wipe the glass with tobacco.
There is also a special film that is glued, like when tinting a car. It is similar to the films used for the visors of motorcycle or racing helmets. But it is advisable to install it in a specialized service, otherwise bubbles will appear under the film, and the result will not please you.
In rainy autumn or winter, water or snow can enter the cabin. During warming up, water evaporates and condenses on the glasses. Therefore, it is very important to remove moisture from the passenger compartment. Shake off snow from your feet before getting into the salon. Clean your interior mats regularly.
Every motorist, no matter what car he drives, has come across such a seemingly insignificant problem, which is fogging of car windows. Contrary to popular opinion, the reason for this phenomenon is alcohol, which is by no means consumed by the driver or passengers of the vehicle, although this factor contributes to an increase in the intensity of fogging.
The danger of this phenomenon lies in a significant deterioration in visibility, leading to a decrease in the control of the traffic situation by the driver of the car, that is, it directly affects the level of traffic safety. How to deal with fogging of car windows?
To determine the optimal and effective methods to combat this phenomenon, it is necessary to understand the reasons for its occurrence.
The fogging process can be easily explained. It is based on the temperature difference between the inside and outside of the vehicle and the increased humidity inside the cabin. Automobile glasses, which serve as the boundary separating air masses of different temperatures, condense excess moisture on themselves.
Therefore, it is quite obvious that the only effective method of combating fogging of windshield (and not only) windows should be measures to minimize the humidity of the air in the car.
So why does the air mass inside the car have a high level of humidity? There are several main reasons for this:

How to eliminate fogging in a car
Currently, there is a whole range of measures to help the car enthusiast fight this negative phenomenon that affects traffic safety. Moreover, this complex includes not only measures for the direct elimination of fogging, but also measures of a preventive nature, helping to exclude the very possibility of the formation of wet fumes. So what to do?
- Regularly produce cleaning the inside of car windows with the obligatory use of high-quality detergents, and after cleaning, wipe them dry with a clean cloth. In addition, try to avoid touching the glass surface with your hands.
- In a timely manner dry interior elements: floor mats, noise insulation, seat upholstery, etc.
- In time replace the cabin filter and cleaning the drain hole of the climate control.
- Regularly inspect possible places of leakage salon.
- Monitor the performance of the vehicle ventilation system.
Ways to eliminate fogging
In the event that car windows are already fogged up (or icy), experts recommend:
- Warm up the car until the windows fog up, while excluding the presence of people in the passenger compartment.
- Turn on the ventilation system in a mode that ensures the flow of air masses from the outside, since the circulation of the air in the cabin is ineffective.
- If the vehicle is equipped with an air conditioning system, turn it on.
Anti-fogging chemicals for glasses
Modern manufacturers offer motorists a wide selection of chemicals (liquid and aerosol) that prevent glass fogging. The principle of action of these drugs is based on the formation of a moisture-repellent film by them, which reduces the coefficient of surface tension of the glass, which prevents the formation and preservation of excess moisture on the surface of automobile glass.
The action of almost all modern means of protecting glass from fogging can be roughly divided into two stages. Initially, the drug acts as a glass cleaner, since it contains cleaning components, and then the cleaned car glass is covered with a specific protective film.
However, in the process of choosing and using chemicals that prevent fogging of automobile windows, there are certain features, the so-called "pitfalls". Preparations of poor quality, of which, unfortunately, there are quite a few on the shelves of domestic auto shops, have a negative feature of leaving a non-drying greasy film on the surface of the auto glass. Traces from it stain the interior upholstery, and streaks and glare that appear on it can significantly complicate the driver's perception of the road situation.
The use of high quality drugs does not threaten the car enthusiast with such complications, but their search will require some effort, and the acquisition of some costs.
As a summary, it must be stated that if your windshield is sweating from the inside, this is a serious problem and it must be solved by no less serious methods and by means of serious means. It was about them that was described above.
