Each motorist probably faced the problem of stamped glass. Many believe that this is possible only in cloudy or crude weather. However, glasses often sweat in the car in winter with dry weather. This is especially true for southern regions where the wet climate is constantly. How to overcome this problem, and why do glass fighter in the car? What to do in such a situation, and what are the reasons, you will learn in our today's article.
Why is this happening?
The main source of this problem in the car is moisture. And it may be not only in crude weather. In combination with cold windows, moisture gives condensate. As a result, small droplets of water are formed on the inner surface of the window and windshield. Of course, it negatively affects visibility and, as a result, the safety of motion.
Often, the removal of excess moisture from the cabin is made by turning on the stove or blowing the windshield. But it does not always give the desired result. Condensate is still formed on the windows. If the machine sweats the glass, the reasons can be different. Let's look at what methods can be eliminated by this problem.
Rugs
Many motorists do not pay attention to this little thing. But precisely because of the rugs, many are sweating the glass in the car. What to do in such a situation? It does not always help replace data of items. By installing other mats into the car's salon, you can still encounter water inside. You need to overcome the source of the problem. Perhaps the problem is hidden in a leakage grid glass seal. As a result, water through drainage enters the salon and on the mats.
Such a problem often occurs on cars who visited serious accidents, where the geometry of the body was improperly restored or replaced by windshield. The next thing to pay attention to is a stove radiator. On most modern cars It is located in the central part of the instrument panel. At the same time on the rugs you can see fatty oily spots. Sometimes they have a certain shade - yellow, red or blue (depending on which antifreeze was used in the system).
If the water accumulated on the rug has a fatty film, is definitely a problem in the refrigeration leakage. It often faces owners of domestic cars, including VAZ 2108-21099. How to achieve tightness? It is necessary to check the condition of the nozzles, which is summed up to the heat exchanger. If they are easily adjacent, replace the clamps. The presence of the slightest cracks on rubber pipes speaks of their leaks. In rare cases, the radiator itself changes (with minor damage it is possible to repair by soldering).
As you can see, wet rugs, in the car's salon installed, can become a symptom of faulty radiator stove. Power on the heater full power Does not solve the problem - so Tosol will run even faster.
Salon filter
Such are all modern cars, including domestic ("Chevrolet Niva" no exception). The cabin filter allows you to prevent dust and dirt from entering the car. The manufacturer advises to replace them once by 20 thousand kilometers. In case the car is used in extreme conditions (for example, frequent riding on dirt roads), this period must be reduced to 8 thousand.
On some premium machines, for example, "Mercedes" of the S-class, is not installed not paper, but coal salon filter. It is better struggling with pollution, but its price is 10-15 times higher than usual. By the way, the replacement regulations are 50-100 thousand kilometers. A contaminated cabin filter can reduce the speed of the air flow in the ventilation system.
How does this affect the accumulation of condensate? Everything is very simple. The clogged cabin filter not only misses the air, but hardly produces moisture. Due to the scored ventilation system, water can accumulate in its cavities and cause not only fogging glass, but also nasty smell. If the glasses sweat in the car, what to do? As a rule, this problem is eliminated by the replacement of the salon filter to the new one. The cost of a paper element is small - only 250-300 rubles.
Adjustment and repair of heating and ventilation systems
If the filter replacement did not help, the cause of the stamped glass can be an incorrectly configured ventilation system. As a result, the air flow does not enter the windshield. To check it, it is enough to put a piece of paper on the air duct. If there is noise and "not blowing" in the stove on the position, you need to look for a break place. Often the nozzle just goes off landing.
As a result, the air is not blowing on the glass, but in the middle of the panel. But to check this, it often has to fully disassemble the front panel. Again, this problem is subject to domestic cars. For example, on "gazelles" these nozzles are made of solid plastic and installed without any fastener, braziness. On the bumps they can simply fly out of the landing place. As a result, you sweat the glass in the car. What to do? Check the condition of the duct nozzles.
Drainage holes
In the autumn-winter season, moisture in the cabin can accumulate not only when you open the doors of the car. Water falls inside and through the ventilation grille. How does this happen? Under the hood at the windshield there are drainage holes for the output of moisture and water. Over time, they are clogged with fallen leaves. As a result, water is not displayed properly and penetrates the nearby ventilation grille. If you are wondering why glasses sweat in the car, pay attention to the purity of the drainage holes. On the eve of the winter you need to check their condition and clean it, if necessary.
In order to get rid of condensate on the windows as much as much as possible, it is possible to carry out the car's interior. It is better to do it in a dry sunny day. Open the fully door and trunk of the car per day. Extra moisture will evaporate even from the most secret places. Thoroughly drying the salon, you will no longer wonder why the glasses sweat in the car.
If the problem of the stamped glass has already nuts, you need to know how to remove moisture from the surface. Many have come across the situation: if we remove the water with inner Glass, the next day there will be strong divorces. It will not be possible to remove them with air conditioning or a strong air stream. But you can fix this problem. Experts recommend using microfiber rags. Them appearance Presented below.
They are highly cleaned moisture from the surface, not leaving the divorces. For a better effect, it is recommended to wipe the glass diagonally. So you will always have a clean glass without divorce.
Features washing
Important moment for those who use high pressure sinks. At the end of the procedure, leave the car open for 5 minutes so that the extra moisture leaves the seals. This is especially true in winter. Also carefully dry the door locks. To speed up the procedure, you can use the hairdryer. Otherwise, the door sticks to seals, and you can not open it. And if you frozen and locks, then there will be no chance to unlock the car. All important places where the door comes into contact with rubber bands, treat a piece of dry vet.
Conclusion
So, we found out why glasses sweat in the car, and how to fix this situation. If you find characteristic oil drips on mats, definitely the problem with the heat exchanger. In the presence of unpleasant odor The cabin filter should be replaced. Well, if the water does not have an oil film and there is no smell inside, the problem is in the drainage holes that are under the hood. All these problems can be solved with their own hands.
Good visibility is one of the key driving parameters of the car. The driver must control the situation around the car at 360 degrees, and for this frontal, side and rear glass, as well as mirrors, should always be clean. In winter, or during the rain you can see the situation when the glasses sweat in the car from the inside. Because of this, visibility is seriously deteriorating, and the operation of the car in such cases is not recommended. As part of this material, we will explain why glass in the car is sweat inside, as well as we give recommendations what to do in such situations.
Explained from a physical point of view the process of fogging the glasses is quite simple. Because of the cold air on the street and warm inside the car, condensate is formed on the border of their junction. Moisture from warm air does not evaporate and settles in small drops on the glasses. Since warm air from the car partially leaves, it settles on the rearview mirrors, which are also fisted at low air temperature outside.
To minimize the process of fogging glass in the car, you need to as much as possible with warm air. In other words, it is required to create inside the car conditions under which the air will be less wet. It comes from this that the main reasons for fogging the windows of the car are as follows:
- Wet seats, shoes or rugs;
- Human respiration, the more passengers in the cabin, the stronger the glasses are fisted;
- Working car stove. It takes the air through a special hole in which rain falls or melting snow, which leads to an increase in air humidity in the car's cabin.
From the above, the reasons for fogging glass in the car can conclude that it is necessary to minimize the amount of moisture in the air circulating in the car.
In most cases, the windows in the car do not stove, it suffices to comply with simple rules:
- When landing into the car, knock on snow or raindrops with shoes;
- Do not put wet things in the car's salon. If it rains on the street and you have a wet umbrella, fold it into the package and maximize the seal;
- Rugs, armchairs must be maintained in a dry state;
- Check the purity of the drainage system under the hood of the car. Before you go on a trip, especially in the autumn time of the year or in winter, remove the foliage / snow from the hood lattice, otherwise, when the stove is turned on, the snow melts, and after the moisture falls into the car's salon.
The recommendations described above allow you to minimize the amount of moisture in the car, which reduces the likelihood of fogging glass. If the glasses still continue to fog, you need to more seriously approach the solution to the problem.
Direct the air conditioner on the glasses
One of the most simple ways Get rid of the problem of fogging glass - this is the air conditioner on them. To do this, you need to include by blowing on maximum speed and direct the air jet directly on the glass. So that the moisture leaves the car's interior faster, you can overlap central holes Air supply. The air conditioner itself dries the air in the cabin and displays moisture.
The air conditioner will allow you to quickly cope with the fogging of the windshield of the machine, but for heating the entire cabin and "drying" of the air he will need more time, so the rear and side glass Risk to remain unsuitable for driving.
Use "Chemistry", preventing fobs of glasses
There are many special Toolswhose task is to combat the formation of droplets on the surface of the glass. In common, they are called "Anti-Layer", "Anti-Congrent" or "Antisputor", and they create a surface on glass that does not allow water to accumulate. The use of "Anti-Layer" is advisable both outside by covering it windshield and in the cabin. Similar funds are 2 species:
If there is a problem with the fogging of glass in winter, you can use conventional washers or agents of the anti class. Their application on the glass in the cabin will allow to overcome the problem with the formation of condensate for 2-3 days, while specialized funds act much longer.
Change the cabin filter
When the question arises, what to do if the glasses sweat in the car even when the air conditioner is turned on, you immediately need to think about the salon filter. When it is contaminated, an obstacle arises to exit the air interior with excessive moisture, and it settles on the glass windows.
W. different models Car cabin filter can be located in different places, and its finding is easiest to determine from the documentation from the car. Also in technical passport Information about the frequency of the salon filter change is prescribed, but in practice, drivers change this "consuming" less frequently than it is recommended, which is why there are problems with the circulation of air in the cabin. At the same time, to change the cabin filter with their own hands is quite simple, and it should be concerned if the windows in the car are stuffed.
If condensate was formed on a glass of car, then it must be deleted, even if the air conditioner is already enabled. Some drivers begin to wipe the glass with a cloth, which they use to clean various contaminants on the car, but it is impossible to do so. Get a separate sponge or microfiber cloth to wipe the glass on the inside. Wipe the windshield should be diagonally so that there are no divorces.
Poverty glass in the car significantly reduce visibility, can cause a traffic accident. Most often with this problem, drivers face in the cold period of operation of the car.
Why windows in the car from the inside sweat and what to do to reduce their "sweating" read further.
Why windows are fought in the car in terms of physical processes
Missing glass in the car is a consequence of the physical process of transition of water from a gaseous state in liquid (condensation). During the parking machine, the air temperature inside the cabin and outside ( ambient) Align both relative humidity.
At the time of landing, the humidity in the cabin and passengers increases significantly due to exhaled air, which contains a large concentration of water vapor. Many drivers know that the effect is repeatedly enhanced if there are alcohol pairs in exhaled air.
Since glass at the time of landing remains cold (its temperature is lower than the dew point), air pairs are instantly condensed on it. Condensation occurs on other elements of the cabin, but it is not essential for visibility.
The video - why the windows in the car are fogged and how to deal with it:
Most effective methods Combating air condensation so as not to sweat the glass in the car:
- heating of glass to a temperature exceeding the dew point;
- powerful blowing glass, leading to reverse evaporation of water;
- application of special means on the inner surface of glass that reduce the sedimentation of vapors that convert the microcapel structure.
Thus, in the cold season, the condensation process, leading to the fogging of glasses in the car, is inevitable. It can be repeatedly intensified under the action of other operating conditions of the vehicle:
- in the winter period of operation of the car, the temperature of the dew point changes, the time increases for the desired glass heating;
- during the rain, the humidity of the air is significantly increasing, the probability of moisture in the salon, due to the kneading drops of glass increases and the time of their warming;
- during the movement of the car immediately after the landing of the driver and passengers in the immense salon, warm the glass is more difficult due to its cooling of counter-air flows.
Causes affecting the increase in the effect of fogging glass in the car
In addition to the above effect, the presence of alcohol vapor near the passenger, the overall operation of the car can increase the fogging of the glass in the car:
- Increased air humidity in the cabin. It can be wet rugs, sitting after contact with wet clothes of the driver and passengers, water that fell into the cabin with bad glass seals, plugs, loosely closing doors, the remaining droplets of rainwater and snow after opening doors, drinking drinks (especially hot) in Salon. All this can significantly increase relative humidity.
- Pollution, wear of the cabin filter. Many drivers do not change the cabin filter for years. The moisture accumulates in its cavity, especially in the summer period of operation of the car during the frequent activation of the air conditioner.
- The incorrect operation of the blades of the blade system of the salon. In this case, the recycling of air flows in the cabin can be broken, efficiency forced ventilation The air is significantly reduced. Excessive moisture from the cabin in this case during the movement of the car will not be removed.
- Radiator leakage stove. Even a minor leakage of antifreeze from the radiator of the stove or pipes, which is not detected by visually and human smell, can increase relative humidity in the cabin. It is possible to detect a possible small leakage of the stove radiator according to the characteristic oily flap on the inner surface of the windshield.
- Frequent car wash.If the car is not new, door seals, glasses are wear. At the time of washing, especially under high pressure, moisture penetrates into the car, which completely does not have time to leave the cabin until the next procedure.
What to do if the windows are fled from the inside
A set of measures to reduce the effect of fogging windows from the inside can be divided into preventive and operational.
Preventive measures include:
- Timely replacement of the cabin filter. It is best to change the cabin filter while changing the seasons of the car's operation: cold - warm and warm - cold, that is, twice a year. If the machine is not operated in tense mode, it is enough to replace the cabin filter once a year - at the end of the warm period of operation. Simultaneously with the replacement of the filter, clean the inner cavity of the filter installation site, pallet and condensate drain holes.
- Periodic cleaning machine salon.During the operation of the car during the cold season, especially after prolonged precipitation, it is necessary to periodically dry non-resident rugs and seat covers, if any. They like a sponge absorb moisture. Drying can be done by placing them overnight on the heating radiator. To dry out the salon, you can leave a car in a dry heated garage with open doors. there is special materials type silica gel (bags with it sometimes placed in high-quality shoes when pre-sale preparation), Which absorb moisture. To absorb moisture from the volume of the machine, it will take at least 1 kg of material. It is dried on the heating battery, then put on a day in the cabin car, after which they dried again.
- Regulation of ventilation salon. Before the cold period of operation of the machine, it is necessary to check the efficiency of all regulators and valves responsible for the redistribution of air heating and ventilation fluxes, if necessary, repair them.

Operational measures to eliminate fogging glass in the car:
- Permanent availability in the cabin of a soft dry car for wiping the glasses.Practically, you must have a minimum of two cloth napkins, one of which is kept at home on drying, the other is in the car. At the end of the trip, they change places.
- Processing the inner surface of the glass with special means. The simplest means is a homemade aqueous soap solution of low concentration. It changes the superficial tension of the glass material. Moisture rolls in microcliga, which practically do not interfere with visibility. At a negative temperature, this mixture is ineffective. Some motorists make up a mixture using glycerin, but it causes glare to dark time day. In the car market you can find many special means of chemical origin. Each of them is effectively effective, they should be selected by their experimental way.
- Glass coating with a special nanowillion. Such a coating is made in the motorcycle. Before holding such an expensive procedure, you should consult specialists.
- Reduce the number of unnecessary things in the car. They can absorb moisture, especially different blankets, bedspreads, and plaid rugs.
- Less talk to the car, especially during the heating of the cabin.
Additional warnings
To avoid problems, you should not wipe the inner surface of glass with alcohol-containing liquid, as well as means of dubious origin!
One of the problems with which car enthusiasts often face is the fogging of stalk. What are the reasons for fogging the brass in the car and what to do to restore visibility?
Increased air humidity
With a long parking lot of the car, air humidity in the cabin is equal like on the street. Man, sitting in the car, fills the salon with wet air from his breathing. Water droplets, settled on cold glass, create a thin film that limits the review.
The problem of fogging the glass is aggravated during the rain. At the same time, the glasses often sweat so that the car becomes impossible due to the complete lack of visibility. The problem is solved without applying technical means. To restore visibility, you should include blowing the automotive heater on the glass. Visibility will recover in a minute.
For machines equipped with air conditioning, it is better to include it. Just a minute to eliminate fogging, it copes better "stoves". At the same time, turn the blower switch to the "headshield only" position.
In winter, fogging machines occurs when the engine starts when the temperature in the cabin and on the street is different. It should be enabled by blowing on the windshield, and as the interior is heated to switch to other positions.
If the cause of the fog is consigned only in high humidity, possibly using special compositions To prevent fogging Steak car. Made in the form of spray, they are easily applied and provide a long effect. The cost of such compositions: from 200 rubles.
Wet rugs under the legs
Despite the fact that wet mats are the cause of high humidity (which could be attributed to the first item), such situations should be considered separately.
First, it is necessary to find the cause of moisture on the rugs - it is possible to the salon that the water is falling due to worn out door seals or the windshield seal. If it is so, you should replace them.
Another reason is the flow of the "stove" radiator, which is located under the instrument panel on most cars. At the same time, the glasses do not sweat in the generally accepted understanding of this word, and are covered with a fatty film consisting of a cooling liquid droplets. Remove such a film can only be used to clean the brake. Wipe the dry cloth exacerbates the situation.
As a rule, noticing a slightly swollen glass, the driver directs the stream warm air. When coolant leakage, such actions lead to a rapid fogging enhancement. This is one of the diagnostic signs of a malfunction. In addition, during the leaks of the radiator under the rug in the driver's feet, the driver often detected to detect leaks of antifreeze. Repair is to replace the radiator, checking the tightness of connections of pipes.
Secondly, at least once every six months fully air car interior. To do this, you need to open all the doors, the trunk and leave the car to dry with a warm air temperature per day. So you can dry the entire interior and remove excess moisture.
Salon filter
The cause of the fogging of the glass often becomes a clogged cabin filter. Over the summer, a lot of road dust falls into it, the leaves, which disrupts the conductivity of the air through it. At the first autumn rains, such a filter reaches and completely ceases to perform its function. A wet and poorly purified air begins to the cabin.
With the onset of the coldness of many drivers, the same problem combines the same problem: fading windshield in the car, and not only in the rain or snow, but also in dry weather. This phenomenon is especially dangerous in winter, when ice crust is almost immediately beginning to form on the glass, therefore, it is advisable to eliminate the causes before the onset of cold weather.
Why fading windshield
Before overcome fogging glass in the car, you will have to figure out why this phenomenon occurs. Actually, the only cause of fogging is increased humidity in the cabin of the car. It remains only to find out where it is from.
- First, the moisture is contained in the air, exhaled by all located in the cabin. By the way, the well-known pun "sweat the glasses from the inside - drink less" has a real basis, because the alcohol pairs (due to their hygroscopicity) collect around themselves a lot of moisture around themselves, therefore the car's glass is stuffing even more intensively. It is worth noting that the smaller the people in the cabin talk, the smaller the wet air exhale, and the slower moisture settles on the glasses.
- The second reason for high humidity in the car's cabin is wet clothing, mats, seats, so the problem is aggravated in the rain. The moisture gradually evaporates and immediately condenses on the windows. Many car owners are perplexed: why the stove is turned on, the fan works, and the windows are "delayed" even stronger. The reason is very simple: the more hot and intensively blowings, the faster the moisture evaporates.
- The third reason leading to the occurrence of a problem - worn seals of doors and glasses through which water falls into the cabin. To determine that it is time to pay attention to the sealing pretty easily: if the floor's upholstery rain and the rear shelf are constantly moat, it means that the seals do not cope with their task. In addition, their appearance can also be said about many things: as wear, cracks and ruptures begin to appear in them.
- Another reason for the fogging of glasses from the inside of the car (although quite rare, but still occurring machines with climate control systems) - closed drainer air conditioner. Condensate instead of pouring, remains inside the system, and the passing air is overly moistened. In this case, to cope with the problem of foaming, it is enough to clean the drain hole.
- In addition, the problem may wage in the jammed ducts, which is why air flows are incorrectly redistributed. For their repair will have to disassemble the torpedo. The procedure, of course, troublesome, but necessary.
How to deal with fogging glass
The most reliable means against fogging glass is heating. If the rear window is moving - everything is simple: it is enough to turn on its heating, and the entire condensate will evaporate. In many modern carsThe windshield is equipped with electric heating. As for the rest, the main thing is to prevent moisture settlement. Air flows need to redistribute so that as many air can fall on the windows. 
Contemporary cars have a function of intense blowing glass, thanks to which even completely duned glass can be quickly transparent. Often, at the same time, enough air falls on the side glasses, clearing them.
It is important to note one circumstance: the air for blowing should not be taken from the inside of the salon, where it is wet, but from the street. Often, a clogged cabin filter becomes often the cause of stuffing windows of the car. Its transmitting ability deteriorates, and part of the air is captured from the cabin, so you need to monitor its condition and change in a timely manner. In addition, instead of the usual, you can purchase a carbon filter. He dries air passing through it, and glass, not only the windshield, but also others, fogged less.
By car equipped with air conditioning, you can turn it on in parallel with the stove, if possible. Air passing through air conditioning becomes less wet. By car with climate control system, this function, as a rule, works automatically.
It has long been noticed that the less often the driver ishes the glass, the stronger the condensate is settled on them. Therefore, it is necessary to regularly wipe them. In addition, clean glasses do not give glare at night when the car is illuminated by the oncoming machines, thus riding becomes safer.
As for the rugs, it is necessary to regularly shake with rubber, ice and water, and textiles need a periodic drying, especially if they drove into the rain. Many car owners in winter are put under the feet of the newspaper. It is also not deprived of meaning, because paper absorbs water well. You only need to constantly change them, because otherwise, it is the newspapers that become a source of high humidity in the car. 
Use of fogging equipment
There are various aerosols that prevent moisture condensation on the glasses, but choose means against fogs should be carefully. Some formulations for spraying form a fatty film on a glass that greatly gloves in the light of the headlight. High-quality funds are quite expensive, but they are proper use Completely invisible and do not require subsequent removal. It should be remembered that any means of fogging glass is an extra "chemistry" that will be constantly present in the cabin, and even the quality composition is needed with caution.
Dedovsky Method Obtain the windshield of the car with salt wrapped in a rag, thereby eliminating the possibility of his fogging, it is better not to apply, because salted water flowing from the glass will become a corrosion source, and where the window is blown up with white salt divorces, see which that - It is very problematic.
