Misted glass. How to effectively deal with fogging of windows in the car? Some motorists, trying to overcome condensate, treat windows from the inside with special compounds and liquids - the so-called anti-foggers

The problem of fogging windows in a car is familiar to all motorists, this usually happens after rain, with high humidity. Nevertheless, with the onset of autumn and the first cold weather, the windows, as they say, simply flow. If you want to know why windows are leaking and how to get rid of it, read our article.

Is it worth it to deal with fogging car windows?

Many motorists do not even pay attention to the fact that their windows are fogged up, and some are trying in every possible way to solve this problem. Maybe really put up with it and continue to ride, not paying attention!? - Not! It is necessary to solve the problem of fogging windows in the car, since your safety and the condition of the interior in the car depend on it.

Firstly, if your car windows fog up, this affects the visibility of the road, or rather, you will not have complete information about the traffic situation, since you will not be able to side mirrors and a rearview mirror. Because of this, every maneuver you make will carry the risk and danger that you will not notice a car moving in the same or opposite direction, as well as their signs. Secondly, constantly high humidity in the car negatively affects the interior elements. That is why it is best to use various methods to prevent increased humidity in the cabin and in particular fogging of the windows.

Why do car windows sweat?

Fogging windows is a normal physical process. Which occurs due to the fact that there is warm air in the car and high humidity, and it is quite cool or very humid outside. Due to the fact that there is no good air exchange in the car, high humidity and temperature differences are reflected on the windows.

Here it is impossible not to mention another fairly common reason for the fogging of glasses - the presence of a passenger who has consumed alcohol, the fumes immediately affect the humidity of the glasses in the cool season. But this problem, let's say, is temporary, so we won't dwell on it too much.

What to do if the windows in the car sweat?

So, what to do if you are tired of the problem of fogging windows in the car? As mentioned above, it is necessary to establish the cause of high humidity. Most often it consists in poor ventilation of the car interior. To do this, we recommend that you check air filter cabin, it is possible that a large amount of dust and dirt has accumulated on it, so it simply no longer lets air into the cabin from the outside. If you changed the air filter, or it is clean, and the fogging problem is relevant, then you can try to solve it in another way.

Exist special means from fogging windows. Thanks to them, the glass in your car, even with very high humidity, will be dry. We recommend giving preference to products from well-known manufacturers, although they are more expensive, but the effect will be much better than from cheap ones. When applying this tool, be very careful, as it contains a large amount of harmful chemical components. The way to use it is simple. To do this, you need to thoroughly wash the windows of your car and apply this remedy from fogging on the glass, then carefully rub with a rag, over the entire surface of the glass with inside. If the tool includes the possibility of applying to the glass from the outside, then perform this procedure, and do not forget to apply it to the side mirrors.

You can quickly remove moisture from the windows of the car by slightly opening the front windows, thanks to the flow of fresh air, fogging will immediately come off the windows. But at the same time, it is not very willing to open windows in heavy rain, a blizzard or in very cold weather. You can solve the problem with car air conditioner by directing the air ducts to the glass. The glasses will warm up quickly, and the moisture will come off them. For rear window heating can be used, if available. It will also heat the glass, which will help the moisture to drain from it.

If necessary, you can install a heater for the rear window of the car, if there is none. We also recommend installing heated side mirrors, if not available. This is a very useful feature that will prevent fogging of the mirrors during rain and when snow sticks to them.

In general, solving the problem of fogging windows in a car is quite easy and there are a lot of ways and means for this. By the way, speaking of autumn and winter, it is worth recalling

So, raise your hands those who have windows in the car never, ever sweat! What, there aren't any? It's OK! From time to time, the windows fog up in absolutely any car. Whether it's an old grandfather "Moskvich" or a brand new BMW with an "anti-condensation" system. Only in some cars this happens all the time, in others - less often.

Therefore, let's figure out why the windows in the car sweat and what it threatens. And we will find out what to do to prevent fogging or eliminate existing perspiration. We will study all the known methods and decide which ones really work and which do not bring any practical benefit. Content:

What are the dangers of misted windows?

The fact that driving with misted windows is very unpleasant is an indisputable fact. You can’t see anything, it’s difficult to change lanes, there is a risk of hitting a curb or not noticing a sign and getting a fine for it.

In addition, when the windows in the car are constantly sweating, this indirectly indicates high humidity in the cabin. Because of this, metal parts corrode faster, and textile elements become moldy. The air in the car becomes stale.

Even if you do not see obvious mold, this does not mean that everything is fine. Under the influence of dampness, fabric upholstery quickly loses its attractiveness and strength. Yes, and some mechanisms at one fine moment can jam sharply. A car is a very expensive thing, and it’s a shame to tears when you notice even a small scratch or a trace of rust on your swallow.

We agree in advance with your silent protest: it is hard to imagine that modern machines"sweated" enough to provoke the development of mold and rust. In old domestic models, this may have been the case, but in new ones you need to try very hard so that the interior begins to rot: do not dry it in time, constantly bring dampness into it.

However the main problem Wet windows are by no means in insufficient comfort. The worst thing that misted windows lead to is an increased accident rate.

You don’t have to look far for an example: you started to back out and didn’t notice your grandmother hurrying to the store. Or they decided to overtake the car in front, but because of the misted windows and mirrors, they did not see that the rear car also began to overtake. And what is maneuvering in the parking lot! In conditions of insufficient visibility, you can damage your own car, and at the same time several strangers. It’s good if you don’t crush a child or some animal at the same time.

And everyone understands: sweat on the windows is very bad and very dangerous. Do not drive with foggy windows. Everyone understands, but not everyone struggles with it.

Do you know why the windows in the car sweat? Many will now joke that due to the fact that one of the passengers is traveling with a hangover. Yes, alcohol "exhaust" enhances evaporation, but is not the main factor.

To understand why the windows in the car sweat, you need to remember the school physics course: the appearance of condensate is always associated either with temperature changes or high humidity. That is why most often glasses sweat in winter (when there is a large temperature difference between the outer and inner surfaces of the glass) or during rain (when the air is saturated with water vapor).

In this regard, there are 3 main reasons for fogging car windows:

• Human breath. The more people in the car, the more the windows sweat.
• Humid air intake from outside. If it is damp outside, then during the operation of the ventilation system and the stove, all this moisture is drawn into the cabin.
• Dampness in the cabin. It is caused by wet carpets, wet shoes, wet clothes in the car, etc.

What to do? Obviously, you can get rid of fogging of glasses either by reducing the humidity in the cabin, or by good ventilation of the car.

What to do if the glass in the car sweats: useless methods

So, why do the windows in the car sweat, figured it out. It remains to decide what to do with it. If you rummage through the Internet… Although, most likely, you have already done this and found a lot of completely useless tips that do not work in practice. All of them are aimed solely at eliminating the causes of fogging of glasses. We will analyze a few of them:

Tip #1: Get in the car with clean shoes. Do whatever you want: dust off your feet before getting into the car, keep a brush or broom under the seat to shine shoes. The main thing - do not bring dampness into the cabin. And then the glass will sweat less.

The advice is not devoid of logic. Yes, the less moisture is brought into the cabin, the better for the car. However, how do you imagine it? In the summer, will you spank in the puddles in shoe covers, and in the winter, pick out the snow from the tread of your boots for half an hour? Or will you start a "shift" purely for driving, and each time you will carefully pack street shoes in a bag? Then give the passengers slippers at the entrance.

Tip #2: Use rubber mats. They save when you don't have time to shake snow or water off your feet.

Actually, most Russians do just that - they use rubber coasters. As the snow melts, it forms a puddle on the carpet. Then you just pour water into the street and that's it. This method, again, is intended more to protect the underbody of the car from corrosion than to prevent perspiration. From the use of glass mats in the car, they will not sweat less.

Tip #3: Don't carry wet clothes in your car. As a last resort, pack them in a plastic bag.

In combination with all the activities, this method may play some role. But, first of all, which of us always carries bags with us to pack raw items? And secondly, if the ventilation in the cabin is poor, then the windows in the car will continue to sweat.

Tip #4: Use your stove and ventilation system correctly. If it is humid outside, it is better to switch the systems to circular air circulation (recirculation) mode, that is, without capturing street air masses.

A completely stupid idea. Some "specialists" even claim that when the air from the passenger compartment is repeatedly driven through the stove, it becomes drier, which makes the windows in the car stop sweating. As practice shows, everything happens exactly the opposite: when recycling, the glass of a car is instantly covered with a dense layer of perspiration.

So, no matter what site you go to, everywhere they seriously recommend exactly these methods of combating fogging. automotive glass. You can follow these four tips 100%, but you will still wonder why the windows in your car are sweating like before. And all because these methods DO NOT WORK!

As we have already understood, removing wet objects from the passenger compartment practically does not help to get rid of condensation on car windows. Especially if you are traveling with the whole family. The more you are in the car, the more the windows sweat. You won’t say to your spouse: “Honey, I have condensation on the windows from you and your children, can you take a taxi ?!”

So how do you lower the humidity in your car? - Of course, with the help of the most ordinary ventilation! And also with the help of drying the cabin.

1. Dry the interior well before driving. It would be a good idea to ventilate the car before warming up. Then the glass will sweat less.
2. Maintain the vehicle's ventilation system in good condition. Check if the filters are clogged, if the valves work well.
3. When driving in rainy weather, slightly lower the windows, and at the end of the trip, keep the car doors open for a while. And in winter, some far-sighted drivers switch from the stove to cold air a few minutes before stopping. This not only helps to minimize the risk of fogging on the next ride, but also prevents the formation of ice on the body.
4. If signs of fogging appear, turn on the ventilation of the passenger compartment to the maximum, directing the airflow to the windows.
5. Have clean, dry wipes for wiping windows in the cabin. They are needed if you are in a hurry and cannot wait for the blower to dry the perspiration.
6. Check the air circulation in the cabin. The free movement of air masses can be hindered by too large and dense curtains, clothes hung on hooks and a pile of luggage in the cabin. It is also worth checking how the ventilation shafts in the trunk work.
7. Modify the trunk by cutting small openings in the side trim. Yes, sometimes the answer to the question of why the windows in the car are sweating lies precisely in the insufficient air exchange between the cabin and luggage compartments. Even with a normally functioning mine! In this case, cuts are made in the skin, and then they are carefully closed with plastic gratings. Car owners rarely resort to such a cardinal method, but those who, with pain in their hearts, decided on such fanaticism are satisfied with the result.

The use of anti-fogging chemicals

So, the main reason why the windows in the car sweat is insufficient ventilation of the passenger compartment. However, when there is no time for thorough ventilation of the car, and there is especially no time to wipe the windows with a napkin, special chemicals come to the rescue in the form of a liquid, aerosol or mastic.

They prevent condensation from forming and prevent water droplets from adhering to the glass. Such funds perfectly cope with their task, one application is enough for several trips. Main disadvantage of such "anti-foggers" lies in the fact that they must be applied mainly on clean, dry surfaces. Otherwise, the effect will be null. The rules for applying such products are indicated on the packaging, so we will not go into details.

If you don’t want to spend money on special substances, you can easily get by with liquids like Anti-Ice or Anti-Freeze. A good effect is given by ordinary ethyl alcohol, especially if it is mixed with glycerin (in a ratio of 20: 1).

Conclusion

We repeat: there are many answers to the question of why the windows in the car sweat, and the main one is poor ventilation. Meanwhile, for some drivers, perspiration on the windows is caused by a clogged cabin filter, for others it is a violation of the outflow of air in the trunk, and for others it is simply diesel car, which, in principle, does not warm up well, although it is blown normally. Each case should be dealt with individually.

If there are no problems with ventilation, ventilate the interior, turn on the airflow on full power, and after a couple of minutes enjoy good visibility of the glass.

However, for greater confidence in protection from perspiration, we still recommend that you once again not neglect the cleanliness of the cabin: shake off snow from your shoes, do not spill drinks (especially alcoholic) inside the car and do not throw wet things on the seats.

Misted glass is very dangerous. If the windows in your car are sweating, then you must fix this problem as soon as possible. Unfortunately, not all motorists know the causes of fogging of windows in the car and how it can be prevented. We suggest you learn more about how to solve this problem.

Moisture is the main reason for the fogging of the windows in the car. Many people mistakenly believe that windows can only fog up when it's raining outside. In fact, in any and in dry warm weather, the windows can be completely covered with moisture, which makes it difficult for the driver to see.

The whole thing turns out to be in humid air. The more humidity outside, the more likely it is that the windows will start to fog up. And it already depends on the climate in the region where you live. For example, if you live in southern regions with a humid climate, then you probably often encounter this glass problem.

If the air has a high humidity, but it will be cold, then there is a chance that the windows will fog up due to the formation of condensate (small drops of water).

In most cases, many motorists, when fogging their windows, turn on the stove or increase the blowing of warm air windshield and other car windows. But this doesn't always help. Why do you think? Let's try to find out the most common causes when the glasses sweat and what needs to be done for this in order to prevent the problem from occurring again in the future.

1. Replace cabin air filter

Faced with severe fogging of the windows, many drivers basically cannot find the reason why this happens, not even suspecting that everything is much easier than it seems, replacing the old cabin filter in the car with a new one and that's it. The fact is that the most common cause of fogging of glasses is a dirty cabin air filter. As a rule, it needs to be changed every 15,000-20,000 kilometers.

A dirty filter reduces the air flow in the ventilation system. As a result, excess moisture that has collected in the car cannot leave the passenger compartment. Please note that it is advisable to buy a cabin filter with activated carbon. Such a filter will not only purify dirty air (dust, pollen and other substances) coming from the street, but also prevent harmful chemical compounds from entering the cabin.

The cabin filter can be located in different places of the car. Each manufacturer installs the filter in different places. If you think that it is very difficult to change this element on your own, then this is not so. It's actually very easy to do this. And you can find out directly how to change the cabin filter.

2. Correctly adjust the ventilation and heating of the cabin

If the windows in your car fog up too quickly, then there is a possibility or it is possible that you have not set up the ventilation system and the interior heating system correctly. If the air humidity is very high and the windows sweat very quickly, then it is necessary to turn on the blower at the highest speed, directing the air streams to the windshield. We advise you to quickly remove moisture from the machine, it is necessary to close the central air outlets.

Thus, you will ensure maximum air flow directed to the fogged windshield.

In addition, if your car is equipped with air conditioning, it can be a great helper for the fastest possible removal of moisture from the windows and from the car interior. from the cabin and dries the air very quickly.

3. Penetration of moisture into the cabin

As a rule, in the autumn-winter season, most drivers most often encounter fogging car windows. The reason is this. Moisture enters the passenger compartment not only when you open the car doors and it penetrates further through the ventilation system of the car. The fact is that under the hood of almost every car (usually under the windshield) there are drainage holes to remove water and moisture.

They are often clogged with mud or tree leaves. As a result, excess water and moisture are not properly removed outside, but immediately enter the nearby ventilation system.

For example, rainwater, accumulating under the hood, sooner or later passes through the filters, forming moisture, which then enters the cabin.

Therefore, if you do not know what and why the windows in the interior of your car are sweating, then immediately check the condition of the drainage system under the hood of the car.

4. Use regular sponges and wipes

Unfortunately, citizens motorists, air system and air conditioning can not always help you make the glass as transparent as possible. The fact is that very often the moisture that has collected on the glass leaves marks and stains that make it difficult to see through the glass of a car and thereby strain our eyesight.

Therefore, in order to make the glasses as transparent as possible, it is necessary to use ordinary microfiber sponges and napkins (rags). With them you can clean the glass, thereby removing the remaining stains and stripes.

Please note that in order to clean the glass from moisture as cleanly as possible, you cannot wipe the accumulated moisture with a rag or sponge, both horizontally and vertically. It is advisable to wipe the glass diagonally, following strictly in one direction.

Every motorist has probably encountered the problem of fogged windows. Many people think that this is only possible in cloudy or wet weather. However, the windows in the car often sweat in winter when the weather is dry. This is especially true for the southern regions, where the climate is constantly humid. How to overcome this problem, and why do the windows in the car sweat? 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 a car is moisture. And it can be not only in wet weather. In combination with cold glasses, moisture forms condensate. As a result, small drops of water form on the inner surface of the window and windshield. Of course, this negatively affects visibility and, as a result, traffic safety.

Often, excess moisture is removed from the passenger compartment by turning on the stove or blowing the windshield. But this does not always give the desired result. There is still condensation on the windows. If the windows are sweating in the car, the reasons may be different. Let's look at how we can fix this problem.

Rugs

Many motorists do not pay attention to this trifle. But it is precisely because of the rugs that many sweat the windows in the car. What to do in such a situation? Replacing these elements does not always help. Having installed other floor mats in the car interior, you may still encounter the fact that water will accumulate inside. You need to overcome the source of the problem. Perhaps the problem lies in a leaky windshield seal. As a result, water through the drainage enters the interior and onto the floor mats.

This problem often occurs on cars that have been in serious accidents, where the body geometry was incorrectly restored or the windshield was poorly replaced. The next thing you need to pay attention to is the stove radiator. On most modern cars it is located in the center of the instrument panel. At the same time, you can see greasy oily spots on the rugs. 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 mat has a greasy film, the problem is definitely a coolant leak. Owners of domestic cars often face it, including VAZ 2108-21099. How to achieve tightness? It is necessary to check the condition of the pipes that are connected to the heat exchanger. If they are loose, replace the clamps as well. The presence of the slightest cracks on the rubber pipes indicates their leakage. In rare cases, the radiator itself changes (in case of minor damage, repair by soldering is possible).

As you can see, wet floor mats installed in the car interior can be a symptom of a faulty stove radiator. Turning on the heater at full power will not solve the problem - so the antifreeze will run even faster.

cabin filter

All are equipped with this modern cars, including domestic ones ("Chevrolet Niva" is no exception). The cabin filter helps prevent dust and dirt from entering the car. The manufacturer advises to replace them once every 20 thousand kilometers. If the car is used in extreme conditions (for example, frequent driving on dirt roads), this period should be reduced to 8 thousand.

On some premium cars, for example, the Mercedes S-Class, not a paper, but a carbon cabin filter is installed. It fights pollution better, but its price is 10-15 times higher than usual. By the way, the replacement schedule is 50-100 thousand kilometers. A dirty cabin filter can reduce the airflow in the ventilation system.

How does this affect the accumulation of condensate? Everything is very simple. A clogged cabin air filter not only doesn't let air through, but it also makes it difficult for moisture to escape. Due to a clogged ventilation system, water can accumulate in its cavities and cause not only fogging of the windows, but also an unpleasant smell. If the windows in the car sweat, what should I do? As a rule, this problem is eliminated by replacing the cabin filter with a new one. The cost of a paper element is low - only 250-300 rubles.

Adjustment and repair of the heating and ventilation system

If replacing the filter does not help, misted windows may be caused by an incorrectly configured ventilation system. As a result, the air flow does not enter the windshield. To check this, just put a piece of paper on the air duct. If the stove makes noise and “does not blow” in the on position, you need to look for the place of the break. Often the pipe just comes off the seat.

As a result, the air does not blow on the glass, but in the middle of the panel. But to check this, you often have to completely disassemble the front panel. Again, this problem is domestic cars. For example, on GAZelles, these pipes are made of hard plastic and are installed without any fasteners, overlapping. On bumps, they can simply fly out of the seat. As a result, your car windows sweat. What to do? Check the condition of the air ducts.

drainage holes

In the autumn-winter season, moisture in the cabin can accumulate not only when you open the car doors. Water gets inside and through the ventilation grille. How does this happen? Under the hood, the windshield has drainage holes to remove moisture and water. Over time, they become clogged with fallen leaves. As a result, water is not properly vented to the outside and enters into the nearby ventilation grill. If you are wondering why the windows in the car are sweating, pay attention to the cleanliness of the drainage holes. In anticipation of winter, you need to check their condition and, if necessary, clean.

To get rid of condensation on the windows as much as possible, ventilate the car interior once a year. It is best to do this on a dry sunny day. Fully open the doors and trunk of the car for a day. Excess moisture will evaporate even from the most secret places. Having thoroughly dried the interior, you will no longer wonder why the windows in the car are sweating.

If the problem of misted glass has already overtaken you, you need to know how to properly remove moisture from the surface. Many faced the situation: if you remove the water from the inside of the glass, the next day there will be strong stains. It will not be possible to remove them with an air conditioner or strong air flow. But this problem can be fixed. Experts recommend using microfiber cloths. Them appearance presented below.

They qualitatively clean moisture from the surface, leaving no streaks. For the best effect, it is recommended to wipe the glass diagonally. So you will always have clean glass without streaks.

Wash features

An important point for those who use pressure washers. At the end of the procedure, leave the car open for 5 minutes so that excess moisture is removed from the seals. This is especially true in winter. Also dry the door locks thoroughly. You can use a hair dryer to speed up the process. Otherwise, the door will stick to the seals and you will not be able to open it. And if the locks also freeze, then there will be no chance at all to unlock the car. All important places where the door comes into contact with rubber bands, treat with a piece of dry rag.

Conclusion

So, we found out why the windows in the car sweat, and how to fix this situation. If you find characteristic oil streaks on the mats, there is definitely a problem with the heat exchanger. In the presence of bad smell cabin filter should be replaced. Well, if the water does not have an oil film and there is no smell inside, the problem is drainage holes that are under the hood. All these problems can be solved by hand.

Misted windows bring car owners a lot of inconvenience. The visibility of the road deteriorates, and the risk of getting into an accident increases. Most often, people face similar problems in rainy weather and in winter. To save drivers from a headache, many manufacturers have begun to produce cars with a glass heating function. However, most vehicle owners are still forced to solve problems on their own.

Far from always clouded windows, on which condensate accumulates, are the result of weather changes or the fact that there is a tipsy passenger in the cabin. There are many other factors that can be eliminated to improve visibility.

Causes of fogging car windows

Of course, the most obvious reason lies in the condensate. When the air temperature is very different from the temperature inside the machine, water droplets form and settle on the glass surface. They are covered in sweat. Also, the deterioration of visibility can be affected by:

• Increased humidity in the car interior. When in rainy weather people get into the car in wet clothes and turn on the stove, this leads to the rapid evaporation of moisture, which settles on the surface of the windshield and side windows.
• Clogged cabin filter. If this device ceases to absorb moisture and dust in the right amount, then condensation will also form on the glasses.
• Faulty valve clean air supply. If the sensor dampers cease to function in normal mode, then the circulation of air flows in the passenger compartment is disturbed.

Also, the problem may lie in the system, which is responsible for a kind of drainage in the car. If the holes for removing excess water are clogged with foliage and dirt, then this often provokes the appearance of perspiration on the glasses.

Typically the solution technical faults in the car helps to get rid of fogging of car windows. But, sometimes the car owner simply has no time to deal with diagnostics or the causes of perspiration are associated with other factors. In this case, you must follow the recommendations that will help solve the problem.

• Get into the car only in clean shoes, so as not to bring excess dampness into the interior. Anyone who has ever got into a car in winter or during heavy rain is well aware that it is simply impossible to completely clean the boots in such a situation. The only way is to wear galoshes or shoe covers on the street. Agree, few people want to become such a “fashionista” and even more so offer such solutions to car passengers.
• Use rubber mats. All the water from the boots accumulates on them, which can be easily poured into the street. These tools protect the bottom of the car from corrosion. However, while the motorist waits for the snow on the tread of the boots to melt and drain onto the mat, the moisture will evaporate and settle on the glass. Therefore, this also does not help to fully solve the problem.
• Setting up the stove and ventilation. When it's humid outside, many people advise simply switching the car's regular fan to air circulation mode, which, it is believed, after numerous runs through the stove, will become much drier. However, in practice, such manipulations with the recirculation of air flows lead to even more fogging.

• The use of salt. Some craftsmen, having read that salt absorbs moisture well, begin to diligently rub glass with it, especially in winter. Of course, this component dissolves snow well and absorbs liquid, but do not forget about the abrasive properties of salt. If you start rubbing her glass, then they will remain small scratches, which will only lead to their greater pollution and wear.

It makes no sense to waste time on the methods described above. It is better to get rid of excess moisture formation using more effective methods.

How to get rid of perspiration

The first thing to do is to replace cabin filter. Drivers rarely think that the service life of this element is no more than 20,000 km. Experts recommend buying new activated carbon filters. Such products perfectly purify the air, and do not allow chemical fumes to enter the cabin.

Other helpful tips to consider include:

• There should always be clean soft wipes in the car interior. If the windows are suddenly fogged up and there is no time to find the root cause of the sweat, then you can clean the windows from the inside and send a fan to them. This will help temporarily solve the problem.

• Trunk work. First of all, it is worth removing all wet things from the luggage compartment and generally making it a rule not to litter it. Also, some car owners cut small openings in the side trim and cover them with plastic bars. Such a cardinal measure allows you to improve the air exchange in the car.
• Hood grille. If snow or dirt accumulates on it, then you should not be lazy to clean this part before each trip.
• Warming up Before driving, especially in winter, it is recommended to first warm up the interior of the vehicle a little. This should be done gradually so as not to create sudden temperature changes. It is best to direct the heating to all windows and turn it on medium.

Sometimes there is no time for such manipulations. In this case, some turn on the stove to the fullest and get not the most best result. To quickly get rid of perspiration, it is recommended to use special formulations.

Specialized defoggers

Easiest to buy special liquid and spray it on car windows. The cost of the anti-fog is from 80 to 600 rubles, depending on the composition of the product. The cheapest drugs use glycerin. However, this liquid leaves iridescent smudges on the glasses.

It is better to give preference to anti-foggers based on mastic. They are more expensive, but much more efficient. After covering the surface with such a tool, drops of water will literally repel from it. The action of such trains is enough for several trips (up to 72 hours).

Important! Liquids of this type will only work if they are applied to clean and dry surfaces. Spraying anti-fogging agent on fogged glass won't change anything.

In winter, it is more rational to use various anti-freeze and anti-ice. They can not only be poured into glass washers, but also sprayed onto windows from the inside of the passenger compartment. These liquids contain alcohol, which keeps surfaces clean longer.

Some make their own defoggers. To do this, it is enough to mix 20 parts of pharmacy alcohol and one share of glycerin. The resulting mixture is poured into a spray bottle and applied to the glass.

There are other methods, using the cheapest means, that help to forget about perspiration.

If there was no specialized fluid nearby, then you can temporarily solve the problem using:

• Shaving foam. The composition is applied in a thin layer on the glass and wiped with a clean cloth.
• Lemon. For this method, it is necessary to cut the fruit and rub it with glass pulp. After that, the surfaces are wiped with a soft cloth.
• Salt. If you use this component correctly, you can achieve good effect. It is enough to fill several paper bags with salt and place them next to the glasses.
• Newspapers. This "grandfather's" tool helps to temporarily clean windows and prevent condensation. It is enough just to wipe the windows with thin paper.
• Soap. With it, you need to draw small squares at the four corners of the glass. After that, the entire surface is wiped with a dry cloth. Thus, a thin protective film is formed on the glasses, and visibility does not deteriorate.

In custody

Most of these methods allow you to get rid of the problem for a while. However, if the glasses begin to sweat with enviable regularity, then it is best to complete diagnostics auto. As preventive measures, it will not be superfluous to periodically ventilate the interior of the car, dry the upholstery, clean the mats and drain the liquid from them in a timely manner. Sometimes moisture accumulates in the soundproofing material. So it's worth finding out possible reasons the appearance of sweat.
