The windows in the car fog up from the inside - what to do?

Absolutely any driver, professional or novice, sooner or later faces a problem when the windows in the car sweat; he doesn’t always understand what to do. The windows of your favorite car, covered with sweat, not only cause discomfort, limiting the driver’s visibility when the vehicle starts to move, but also affect the immediate safety of traffic, and, no matter how sad it may sound, can be the cause of an accident.

Often, motorists do not know why their car windows fog up and how to deal with the problem by wiping the windshield with a rag or sleeve. Let's understand why car windows sweat from the inside and how to correct the situation? First of all, you can use car interior care services alarmauto-vrn.ru - protective coating for glass and special compounds used to treat car surfaces will significantly improve the situation.

Reasons why car windows sweat.

Condensation on glass is a product of an extraordinary physical phenomenon and occurs as a result of steam condensation, in other words, vaporization.

It is in view of this that, one and all, drivers do not attach much importance to the wet windows of their favorite iron horse, considering it an ordinary phenomenon, although there are several reasons for condensation on car windows. So: fogging of car windows, why it happens and what to do:

1. In the cool and winter seasons, the windows in the car become covered with perspiration due to the sharp difference in temperature and humidity between the car interior and the street. The warm air of the car interior interacts with the cold air brought into the car from the street, as a result of which the windows are covered with a thin layer of condensation.

2. This also happens in wet weather, during rain. The reason is not uncommon - the humidity in the cabin increases due to the evaporation of moisture from wet mats, wet clothes of the driver and passengers, and car seats. The stove dries things out, and the evaporating moisture covers the glass with condensation. In addition to wet rugs and clothes, the source of perspiration can be damage to the windshield insulation or damage to the integrity of the car door seals.

3. Contamination or malfunction of the cabin filter, as well as its rare replacement and cleaning, leads to deterioration of air conductivity, and as a result, this is a problem.

4. The windows of your car may also sweat if the valve or sensor that regulates the normal operation of the valve flaps breaks down. Due to these problems, no air flows into the cabin.

5. An oily film on car windows is a dangerous signal of a leak in the radiator, under the dashboard of the car and one of the reasons for foggy windows.

6. Washing your favorite car - moisture gets inside the cabin, but it doesn’t have time to dry.

7. A “cheerful” passenger who is in a tipsy state is also, albeit transiently, the cause of fogging of car windows. Alcohol vapor absorbs moisture and settles on the car windows in the form of condensation.

How to remove fogged windows in a car.

We found out the key reasons why the windows inside the car and the windshield sweat from the inside? Now our task is to try to prevent such a phenomenon, or to easily get rid of the problem. The following steps will help you do this:

1. Correcting the settings of your car’s climate system. A directed flow of warm air blowing on the glass will cope with this. Also, having an air conditioner will allow you to cope with the task in a few minutes.

2. Use of specialized anti-fogging agents, or in other words, anti-fogging agents. With a wide selection on the market today, you can choose anything to suit your taste, in the form of liquids, spray bottles or wipes. The most famous are Ombrello VISIO, Anti-Fog, etc.

3. Preventative ventilation of the car interior, drying it will also help cope with the problem, and you will no longer have the question of what to do about it, like fogging of the car windows.

4. Timely vehicle diagnostics. Do not forget to replace or clean the cabin filters, evaluate the serviceability of the valve or sensor that regulates the operation of the valve flaps, as well as the radiator.

5. A simple action will help you deal with condensation on the side windows. You just need to open the side windows slightly, the seals will quickly rid the windows of moisture.

6. Turning on the ventilation system together with the stove will cope with the task of eliminating foggy windows. When you turn on only the stove, the air will circulate in a circle without eliminating the problem.

Humid weather and rain, car windows sweat, what to do?

Humid weather and rain provoke condensation on car windows, what should you do if your car windows fog up in this case? A few simple tips will help you deal with this:

1. After you have started driving, you can open the side windows slightly to improve air circulation in the cabin, and after the trip, open the doors slightly to allow fresh air to enter.

2. Carry out preventative drying of the car interior, in particular, on the eve of autumn and winter.

3. Do not leave wet clothes or umbrellas in the cabin, and periodically dry the rugs.

4. Change or clean the cabin filter in a timely manner, as well as troubleshoot the valve or sensor that regulates the operation of the valve flaps.

What to do if your car windows sweat in the winter?

In the winter season, the dilemma of what to do if the windows in the car sweat and how to deal with it is especially relevant. Many modern cars are equipped with heated glass systems, which quickly dry the windows inside the car.

It is also recommended to systematically check the operation of the stove and fan. To get rid of this quickly enough, you need to turn on, in addition to the stove, the ventilation system. Thus, the incoming air from the street will mix with the air inside the car.

If the windshield sweats from the inside, what should you do about this problem? It’s quite simple - to prevent the windows from sweating in the car, the driver can purchase a special compound. It is very convenient to use, comes in the form of liquid and spray, this special product is enough for 2 weeks of use.

The windows in the car fog up from the inside - how to deal with this using folk remedies?

If there are no purchased funds at hand, what to do in this situation? Folk remedies and tricks will come to the rescue:

1. Shaving foam.

Apply a thin layer of shaving cream or gel to the glass, then wipe with a cloth or paper.

Surprising but true! Salt perfectly absorbs moisture, and in order to prevent your car windows from fogging up, you need to place paper bags filled with salt under the glass. The salt will absorb all the condensation, and foggy windows will no longer be a problem for you.

This fruit is a real helper in the fight against fogging of windows; it is easy to buy in any grocery store. Cut the lemon into two parts and wipe the car windows with a towel.

Many experienced drivers wipe their car windows with regular newspaper; it not only removes stains and adds shine, but also perfectly absorbs moisture.

To prevent your car windows from sweating, just draw squares in the corners of the windshield with soap and wipe with a rag. Soap forms a thin film on the window and protects the glass.

6. Self-made anti-fog.

The composition of this unique super-drug includes ethyl alcohol and glycerin, all of which can be easily purchased at a pharmacy within walking distance. The ingredients are mixed in a ratio of 1:20, part glycerin to 20 parts alcohol. For convenience, all that remains is to pour the mixture into a window cleaner spray bottle.

Let's sum it up

The windows in the car sweat: what should the driver do?

During the operation of the car, the driver may encounter various inconveniences. At the same time, the real problem is those that affect not only comfort, but also safety. In practice, in some cases, the headlights may be too weak even after replacing the bulbs, which makes driving at night very difficult. In such a situation, you can solve the problem by polishing the headlights or replacing them.

At the same time, not everyone knows why car windows sweat. Next, we will look at the reasons for fogging of windows in a car, when fogged glass indicates possible malfunctions of the car, and also what to do if the windows in the car are sweating.

The windows in the car fog up: the main reasons

So, if the car windows sweat, it often happens in winter, during rain or fog, that is, in conditions of high humidity. Naturally, visibility in such conditions is usually poor, and if you add to this that the windshield, rear and side windows sweat, the risk of an accident increases significantly.

It also happens that the cause of foggy windows is not only the weather. In any case, you need to know what to do in such a situation and what measures to take to prevent the car windows from sweating. Let's look at the causes and ways to fix the problem.

• Let's start with the simplest one. First of all, in winter, windows sweat because condensation forms as a result of the interaction of warm air inside the cabin and cold air outside. This condensation settles on the glass, causing the car windows to fog up.

• Now let's move on to the less obvious reasons why car windows sweat. For example, if there are passengers in the car who have recently consumed alcohol, then this is the reason why the car windows are sweating.

In fact, alcohol vapors exhaled by a person who drinks alcohol have the ability to absorb moisture, which causes it to settle on the car windows and fog up the car windows.

Also, problems in the interior ventilation system lead to fogging of the glass in a car. Often, we are talking about the interior air filter. Its contamination, defects, model mismatch or errors when installing the cabin filter cause the filter to not absorb moisture and dust properly. The result is foggy windows.

In fact, the damper blocks the flow of outside fresh air, and the air from the cabin circulates in a circle. In certain situations, this function is useful, as it allows you to avoid the entry of dust and unpleasant odors from the outside, the interior can be warmed up or cooled down faster by turning on recirculation, etc.

However, interior air recirculation should not be switched on all the time. If you close the flow of fresh air for a long time (20-40 minutes) or more, the windows will begin to actively sweat, and the driver and passengers may also feel drowsiness, deterioration, etc. The reason is a lack of oxygen, a noticeable increase in air humidity inside the cabin, etc.

If air recirculation is turned off, and the windows still sweat for no apparent reason, the valve through which fresh outside air enters the cabin may break. The sensor that controls the damper may also fail.

It is necessary to study the features of the stove design on a specific car model, carry out diagnostics, etc. If the mat is noticeably wet on both the driver's and passenger's sides, you need to figure out what is leaking and where it is coming from. In this case, you need to take immediate action, since breathing antifreeze or antifreeze vapors is very harmful, serious problems with the engine cooling system are possible, problems with the clutch cannot be ruled out (if brake fluid leaks into your feet from the clutch drive), etc.

What the driver should do to prevent the windows from sweating: ways to fix the problem

So, having figured out the reasons why car windows often sweat, you can move on to what to do in such a situation. Of course, the easiest way is to buy a rag and constantly wipe the glass before driving.

You can also constantly turn on the stove, drying the interior. The downside is the long wait for the engine to warm up during a cold start and for the windows to fog up. True, you can constantly turn on the air conditioner (if available), which quickly “dries” the air and removes moisture, but fuel consumption increases, the life of the air conditioning system decreases, etc.

Moreover, this approach of removing moisture with a rag or using air conditioner does not solve the problem itself, but only allows you to get rid of the consequences. If you need a more effective solution, below we will look at ways to avoid fogging.

The presence of glass that is less prone to fogging, as well as their heating, allows you to quickly dry the windows in your car without turning on the heater or air conditioner. Also in winter, heating the windows allows you to quickly clear the outside of the windows from ice and snow. It turns out that if the problem of glass fogging is acute for the driver, this feature must be taken into account at the stage of selecting a car.

• Let's move on. To reduce glass fogging, you also need to periodically service the heating and ventilation system of the car interior, check the operation of the stove, fan, etc. As mentioned above, you need to promptly change the cabin filter and turn off recirculation.

You can also stick a special film on the glass that resembles tinting. This film also has the property of preventing the accumulation of moisture on car windows. In addition, there is another solution - a defogging agent for car windows.

If desired, you can make your own anti-fog at home by mixing denatured or ethyl alcohol with glycerin. The proportions are 20:1, where 1 is glycerin. Then it is better to place the mixture in a spray bottle for ease of application.

How to remove moisture from car windows quickly and effectively

First of all, if there is snow or ice on the glass, you first need to wait until it thaws, then the glass should be cleaned. While the ice is on the glass, it will sweat from the inside even with intense blowing of warm air.

To quickly clear the windshield and side windows from fogging, you first need to ask everyone to get out of the car (if there are passengers), then wait until the heater starts blowing barely warm air.

Next, turn off the air recirculation function (if equipped), allowing fresh air to enter from outside. By adjusting the deflectors, try to direct the warm air flow towards the glass.

However, in cold winters you need to be careful, as a sudden change in temperature can cause the glass to crack. To prevent this from happening, after removing snow and ice, you should gradually heat the glass, increasing the temperature.

In this case, there is no need to heat the engine and stove, since the temperature of the air blown onto the glass does not have a strong effect in this case. To prevent the rear window from sweating, its heating must be turned on immediately along with the engine.

After the windows have been cleaned, you can turn on recirculation to prevent the windows from sweating further during the trip. However, increased humidity in the cabin can cause windows with recirculation turned on to fog up again. In this case, you need to try options depending on the situation.

Useful tips

As you can see, in order for the car windows not to sweat in the rain or snow, an important condition is to ensure the most effective ventilation of the interior. In practice, sometimes, instead of waiting for the stove to dry out the moisture, it is better to open the windows a little.

To dry the rear window, you can turn on the heating. If this does not help, then you can install a small fan or interior heater that runs from a car outlet or cigarette lighter.

Also, you should not leave wet or damp things (umbrellas, shoes, jackets, etc.) inside the car. In this case, as it dries, moisture will settle on the glass. It is also recommended to drain the water and thoroughly wipe the rubber mats; heavily wet fabric mats should be removed from the car and dried separately.

Also, especially if the car is in high humidity conditions for a long time, you need to dry the entire interior. This can be done by placing the car in a warm garage or secure parking lot for several days with the windows slightly open.

If the windows sweat while driving and the heater and/or air conditioner cannot cope with the fogging, it is recommended to drive with the side windows slightly open. Also, if it’s hot in the cabin and cold and humid outside, after the trip it’s better to open all the doors for 5-10 minutes so that fresh air can enter the cabin.

Let us also add that if the driver is transporting passengers who have been drinking alcohol, so that the windows do not sweat, it is optimal to ask such passengers to talk less (if possible), since the alcohol vapor they exhale causes the windows to fog up.

Finally, we note that you should not try to remove frozen ice from the glass using windshield wipers. This can not only damage the wiper blade, but also scratch the glass itself.

To quickly remove ice from glass, it is better to use brushes, carefully remove the ice with a scraper, or use anti-ice products for glass. It is strictly forbidden to pour hot water on frozen glass! In this case, the glass may burst immediately!

What's the result?

As you can see, the problem of fogging car windows is relevant at different times of the year and affects the vast majority of cars. At the same time, the windows sweat on different cars, both cheap and expensive. The only thing that compares favorably with others is only those models that have separate systems and solutions that prevent windows from fogging up.

How to effectively deal with fogging of car windows?

When the windows in a car fog up from the inside, visibility and visibility are greatly impaired. The driver loses the ability to control the situation on the road, experiences anxiety, inconvenience and discomfort. Operating cars with windows covered in sweat is a common cause of accidents, including fatalities. Let's consider the reasons for this phenomenon, what to do when it occurs and preventive measures.

Reasons why car windows sweat

When the windows become covered with moisture, the driver is forced to take time away from driving the vehicle and periodically wipe the glass with napkins or rags.

Car windows sweat from the inside for the following reasons:

1. The difference in the temperature of the environment and the interior space of the cabin. Similar phenomena occur in the cold season or early in the morning, when the air has not yet warmed up. Moisture from the air settles on surfaces in the form of condensation.
2. Precipitation. During snowfall and rain, the humidity level inside the car increases. Dampness penetrates into the cabin through open doors, windows, and on the clothes and shoes of the driver and passengers. The fumes come from umbrellas and wet rugs.
3. Radiator malfunction. When coolant leaks, a large amount of steam is generated. At the same time, the windshield fogs up, on which oily inclusions appear. It is necessary to stop and check the condition of the cooling system.
4. The filter, which is part of the interior air conditioning equipment, is dirty. It may be clogged with dust or oil fumes.
5. Consequences of washing a car at a car service center. The interior may not have been properly dried after cleaning.
6. Incorrectly configured climate control system or its breakdown. In such cases, the space in the cabin ceases to be dried, and damp air is pumped in.
7. Passengers who have consumed large amounts of alcoholic beverages. During breathing, alcohol vapors are released and settle on the windows. Alcohol absorbs water molecules, resulting in condensation.

How to remove fogged windows in a car?

There are various methods to combat fogging of car windows.

There are general rules for eliminating condensation:

1. Adjusting the air conditioning system. It is necessary to ensure that the windows are constantly blown with warm air.
2. Installation of several high-quality moisture absorbers in the cabin. Sorbents effectively absorb water from the space, drying it to the required condition.
3. Treatment of glass with special agents that have hydrophobic properties. Even water molecules do not linger on them. Such products are produced in the form of aerosols, liquids and impregnated wipes.
4. Opening windows a few millimeters. The resulting air circulation ensures the evaporation of condensation from all surfaces.
5. Ventilation (air ventilation) and preventive drying of the interior. This helps to dry the upholstery of chairs, rugs and remove liquid accumulated in the niches.
6. Regular vehicle maintenance. Timely replacement of filters, sensors and valves will prevent excess moisture.

When it rains, water penetrates into the interior of the car, which, when heated, turns into steam, settling on windows, metal and plastic in the form of tiny drops.

You can get rid of glass fogging in inclement weather in the following ways:

1. After starting to drive, open the windows on both sides of the car. The resulting turbulence will ensure condensation is blown off the panels.
2. After finishing the trip, park the car in a heated garage. If possible, leave windows and doors open to dry out the cabin.
3. Before planting, shake off snow and water from clothes and shoes, pack wet umbrellas in plastic bags or covers.
4. Before the onset of the wet season, warm up the interior with a hairdryer to remove moisture from the upholstery. When damp air penetrates, the fabric plays the role of a sorbent.

During the winter season

During the cold season, the formation of condensation complicates the already difficult road situation. In addition, there is a risk of sweat freezing and ice crusts forming on the windows.

What you can do:

1. Set the maximum heating temperature by directing the air flow to the front panel. Heat in the cab can be eliminated by opening the side windows.
2. Use special preparations against condensation formation. Modern anti-fogging solutions for car windows allow you to get rid of this phenomenon without excessive heating of the interior.
3. Install electrically heated panels. This will require additional costs, but they are offset by the comfort and safety of travel.

Anti-fog films

A good result in the fight against condensation is obtained by covering windows with a special film. The basis of the material is polycarbonate - a polymer with high strength, abrasion resistance and hydrophobic properties. The reverse side has microscopic notches and is smeared with transparent glue. The outer layer repels water molecules, which roll down until a visible layer of perspiration forms.

The gluing process is not particularly difficult. You need to do the following:

• cut a workpiece slightly larger in size than the panel being processed;
• thoroughly wash and degrease the glass, wipe it dry;
• Remove the protective coating from the film, apply it to the panel, and remove air bubbles with a spatula.

Recommendations for removing condensation from glass

There are folk remedies that have been proven over the years, with the help of which condensation on the windshield can be quickly and effectively eliminated. Some of them are part of a driver's camping equipment and are sold at any general store.

The problem of window fogging can be solved in the following ways:

1. Table salt. The panels are rubbed with a saline solution and placed dry in fabric bags on the dashboard.
2. Lemon. You need to take half a lemon and rub it on your windshields and side windows. A pleasant aroma will only improve the comfort inside the cabin.
3. Toilet or laundry soap. In the solid state, arbitrary patterns and lines are applied to the surface. Then, using a slightly damp cloth, rub the soap evenly over the entire area.
4. Shaving cream. It works similarly to soap, but is applied faster and easier.
5. A mixture of alcohol and glycerin. The mixture is made in a ratio of 1:20. Apply to surfaces with a cloth, cotton pads or using a spray bottle.

Before using any products, surfaces must be cleaned of moisture and dirt. This should be done with crumpled newspapers, a clean cloth or sponge.

Prevention of glass fogging

To avoid condensation, you should follow a few simple rules:

1. Before boarding the cabin in conditions of heavy rainfall, place pieces of cellophane, old linoleum or unnecessary rags on top of the mats. They will collect water from the shoes, which can then be easily removed from the interior.
2. Before a long trip, pre-rub the glass with mastic, glycerin or another long-acting product. Always have a supply of anti-icing and de-icing agents on your windows.
3. Periodically dry upholstery and rugs. Dry things can act as a sorbent for a long time.

These methods will reduce the humidity in the cabin and reduce the likelihood of windows fogging in any weather conditions.

The windshield fogs up from the inside - how to fix the problem?

Every motorist, regardless of what car he drives, has encountered such a seemingly insignificant problem as fogging of car windows. Contrary to popular belief, the cause of this phenomenon is not alcohol 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 control of the road 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 optimal and effective methods to combat this phenomenon, it is necessary to understand the causes of its occurrence.

Why does the windshield sweat?

The process of fogging is explained quite simply. It is based on the temperature difference between inside and outside the vehicle and increased humidity inside the cabin. Car windows, which serve as a 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 windshields (and not only) should be measures to minimize the humidity of the air inside the car.

So why do the air masses inside a car have high levels of humidity? There are several main reasons for this:

• Human breathing . Despite the seemingly insignificant amount of moisture released by a person when breathing or talking, it is quite enough to cause the process of fogging. Many car enthusiasts noticed how car windows fogged up literally “before our eyes” after 3-4 people sat in the car.
• Wet elements interior a. Noise insulation, carpets, seat upholstery - all these interior elements are capable of absorbing and retaining moisture that evaporates as the temperature inside the car increases. The ways in which moisture gets into the interior are varied. These are wet clothes and shoes of the driver and passengers of the vehicle. This is a violation of the interior seal in certain places (window seals, antenna cable entry points, windshield wiper arms, etc.) and, as a result, the penetration of rainwater.
• Incorrect operation of climate control . A blockage in the drain hole of this device prevents the removal of condensate formed during its operation. The accumulation of moisture begins to act as an air humidifier and, as a result, the windshield sweats from the inside.
• Untimely replacement of the cabin air filter. A dirty cabin filter significantly reduces the efficiency of the ventilation system, which does not allow reducing the level of humidity in the air masses inside the car.

How to remove fogged windows in a car

Currently, there is a whole range of measures to help motorists combat this negative phenomenon that affects traffic safety. Moreover, this complex includes not only measures to directly eliminate fogging, but also preventive measures that help eliminate the very possibility of the formation of moist vapors. So what to do?

We recommend taking the following steps as preventive measures:

• Regularly clean the inside of car windows with the obligatory use of high-quality detergents, and after cleaning, wipe them dry with a clean rag. In addition, try to avoid touching the surface of the glass with your hands.
• Dry the interior elements in a timely manner : mats, noise insulation, seat upholstery, etc.
• Replace the cabin filter and clean the climate control drain hole in a timely manner
• Regularly inspect possible areas where the interior seal may be compromised.
• Monitor the performance of the vehicle ventilation system.

Methods for removing fogging

If your car windows are already fogged up (or icy), experts recommend:

• Warm up the car until the windows fog up, while eliminating the presence of people in the cabin.
• Turn on the ventilation system in a mode that ensures the supply of air masses from outside, since the circulation of air in the cabin is ineffective.
• If the car is equipped with an air conditioning system, turn it on.

Chemical anti-fog agents for glass

Modern manufacturers offer motorists a wide selection of chemicals (liquid and aerosol) that prevent glass fogging. The principle of operation of these drugs is based on the formation of a moisture-repellent film, which reduces the coefficient of surface tension of the glass, which prevents the formation and retention of excess moisture on the surface of automobile glass.

The effect of almost all modern anti-fog glass protection products can be divided into two stages. Initially, the drug acts as a glass cleaner, since it contains cleaning components, and then the cleaned automobile glass is covered with a specific protective film.

However, in the process of selecting and using chemicals that prevent fogging of car windows, there are certain features, the so-called “pitfalls”. Low-quality preparations, of which, unfortunately, there are quite a few on the shelves of domestic auto stores, have the negative feature of leaving a non-drying greasy film on the surface of the car glass. Traces from it stain the upholstery, and the stains 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, however, searching for them will require some effort, and the acquisition will require 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 using no less serious methods and through serious means. These are the ones that were discussed above.

What to do if your car windows sweat?

What should you do if your car windows sweat?

Foggy windows are very dangerous. If the windows of your car are sweating, you should fix this problem as quickly as possible. Unfortunately, not all motorists know the reasons for fogging of car windows and how it can be prevented. We invite you to learn more about how to solve this problem.

The main reason for fogging up car windows is moisture. Many people mistakenly believe that windows can only fog up when it rains outside. In fact, in any car and in dry, warm weather, the windows can become completely covered with moisture, making it difficult for the driver to see.

It turns out it's all about the humid air. The more humidity it is outside, the more likely it is that the windows will start to fog up. And this 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 problem with glass.

If the air has high humidity and the car windows are cold, then there is a chance that the windows will fog up due to condensation (small drops of water) formed.

In most cases, when the windows fog up, many motorists turn on the heater or increase the flow of warm air onto the windshield and other windows of the car. But this doesn't always help. Why do you think? Let's try to find out the most common reasons when windows sweat and what needs to be done to prevent this problem from happening again in the future.

1. Replace the cabin air filter

Faced with severe fogging of the windows, many drivers generally cannot find the reason why this happens, not even suspecting that everything is much simpler than it seems, it is necessary to replace the old cabin filter in the car with a new one and that’s it. The fact is that the most common cause of glass fogging 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 rate in the ventilation system. As a result, excess moisture collected in the car cannot escape from the cabin. Please note that it is advisable to buy a cabin filter with activated carbon. Such a filter will not only clean dirty air (dust, pollen and other substances) coming from the street, but will 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 yourself, then it is not so. It's actually very easy to do. You can find out how to change the cabin filter right here.

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 possibility that you have incorrectly configured the ventilation system and the interior heating system. If the air humidity is very high and the windows sweat very quickly, then you need to turn on the airflow at the highest speed, directing the air flow to the windshield. We advise you to quickly remove moisture from the machine by closing the central air vents.

This way, you will ensure maximum air flows directed at the foggy windshield.

In addition, if your car is equipped with air conditioning, it can be an excellent assistant for removing moisture from the windows and from the car interior as quickly as possible. The air conditioner removes excess moisture from the interior and dries the air very quickly.

3. Penetration of moisture into the interior

As a rule, in the autumn-winter season, most drivers most often experience fogging of car windows. The reason is this. Moisture enters the interior 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 for removing water and moisture.

They often become clogged with dirt or tree leaves. As a result, excess water and moisture are not properly removed outside, but enter directly into 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 don’t know what and why the windows in your car’s interior sweat, then we advise you to immediately check the condition of the drainage system under the hood of the car.

4. Use regular sponges and napkins

Unfortunately, citizen motorists, the air system and air conditioning cannot always help you make the windows as transparent as possible. The fact is that very often the moisture collected on the glass leaves marks and stains that make it difficult to see through the car window and thereby strain our vision.

Therefore, to make the glass as transparent as possible, you need to use ordinary sponges and microfiber cloths. You can use them to clean the glass, thereby removing any remaining stains and streaks.

Please note that in order to clean the glass from moisture as cleanly as possible, you should not wipe off 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.
