The best improvised means from fogging glasses. To prevent windows from fogging: rules of transparency

Now we will briefly tell you how to get rid of fog on the glasses with the help of potatoes, baby shampoo, hand gel, shaving cream. Against them will act a specialized remedy for fogging glasses.

Steam on glasses is formed when the temperature changes, as well as with the presence of excess moisture in the air. The human body radiates heat, his breath is also warm, in addition, and moist. In winter, in an unheated car, steam will probably condense on the windows if you drink hot tea from a thermos. In the summer, fogging of glasses can also occur - after rain, when the air conditioner is turned on at full power in the cabin.

Test for the best remedy from fogging was carried out on a completely wet door glass, which was divided into five sectors with masking tape.

  1. Top left corner treated with a special anti-fogging agent.
  2. Upper right corner rubbed with a small amount of shaving cream.
  3. Lower left corner been subjected to the old trick some people use to get rid of the fog on a diving mask, which is to wipe it down with baby shampoo.
  4. Lower middle was processed in the legendary way from fogging, which no one has yet tested - grated with cut potatoes.
  5. Last bottom corner smeared with disinfectant hand gel.


All procedures with glass were carried out carefully, not missing a single corner. The glass was rubbed to the degree of complete transparency, without the use of water for rinsing.

After mercilessly treating the glass with hot steam from a mug, let's look at the results.



First place separated shaving cream and a special anti-fog agent, working clean.

Second place received baby shampoo, giving a relapse in the form of thin streams on the glass.

Third place the potatoes deserve it, let's leave even more sweaty stripes on the glass.

Fourth place goes to the hand gel, which did not save its sector from steam. Although many people think that since hand sanitizer contains alcohol, it should better protect the glass from fogging.

As a conclusion, we can say that the purchased anti-fogging agent in the experiment deserves the first place, since it fully justifies its cost, the time spent on going to the car shop.

Well, if there is no time for a trip to a car shop, then every man can find shaving cream. At worst, you can use what lies in the basement of the garage.

Autumn and winter, as well as days of high humidity in summer and spring, are quite difficult for the driver. In many cars, the windows begin to fog up mercilessly, nothing is visible around, and it is impossible to drive in such conditions. Many people advise taking a cloth and wiping the glass, but this does not improve visibility much, since the glass must be dried. As long as moisture is present, the rag simply breeds it, which does not allow you to get the necessary visibility and normal visibility to the outside. The fogging of the windshield is especially disturbing. In this case, the driver simply does not see where to go. However, the rear and side windows are also not very pleasant to leave in this state. Therefore, it is best in this case to find a certain way out of the situation and create the necessary conditions for the trip for yourself. There are many resources available to help in this case.


You can turn to traditional or unusual methods to get out of trouble. In particular, there are recommendations from other drivers that will help to cope with the fogging of windows, and there are tips from companies that produce special chemicals for the car. You can listen to any recommendations, but remember that the cost of implementing the tips will be different. It is quite possible not to spend additional funds and perform high-quality protection against visual obstacles while driving. But you can go to a special store and buy a bottle of a chemical agent for a few hundred rubles. Everyone chooses those methods in which he is confident, so rely entirely on your own views and preferences. In this publication, we will propose different methods and describe how to implement them.

Climate system and cabin filter

The first way to deal with fogging of glasses is to adequately adjust the operation of the climate system. In almost every car, you can set the blower to work directly on the windshield. This will help dry the air faster and achieve a normal result. If your car has air conditioning, be sure to turn it on. It will dry the glass in seconds. Blowing should work with the following features:

  • all air flow should be directed to the windshield, performing a quick and effective drying;
  • even if it’s warm in the car, it’s worth turning on the heating for a while and heating the glass to get rid of fogging;
  • you can open the windows and equalize the temperature in the cabin with the temperature outside, which will eliminate fogging;
  • it is also necessary to increase the blowing intensity, - the stronger the air flow, the higher the productivity of the process;
  • if there is no effect, it is worth checking the cabin filter - it could absorb a lot of moisture and give the effect of fogging.


If you struggle with foggy windows for a long time, you should simply change the cabin filter. By the way, many motorists prefer to drive with air recirculation turned on. In the process of blowing windows, this is not a good idea. It is better to use the air intake from the outside, but at the same time make sure that the cabin filter is in good condition.

Glass treatment with anti-fogging chemicals

  • read the method of applying chemistry to glass, check the complexity of the entire process;
  • use the review search to make sure high quality solution;
  • look at the application options and the need to use an additional tool;
  • evaluate the smell, do not forget that after applying the solution, this smell will remain in the car;
  • read the instructions for the time period during which the solution works.


Any chemistry of this order is applied to a dry and clean surface, so it is often necessary to thoroughly wash all the windows inside the car before applying. But do not rush to apply any chemicals. It is possible that after a high-quality washing of the glass, they themselves will stop sweating, because pollution often becomes the cause of the formation of haze on the glass.

Anti-fogging films - a cardinal solution

If you've been struggling with foggy windows for a long time, you've obviously wondered how motorcyclists ride in their virtually hermetically sealed helmets. With them, that glass should fog up already in the first minutes after the start of the trip, but in reality it may not sweat for hours. A special film is applied to the glass in good helmets, as well as in high-quality retail windows, which performs a number of tasks:

  • protection against the accumulation of moisture and the occurrence of such an unpleasant phenomenon as fogging;
  • very easy cleaning with soft cloths - no streaks or glare remain;
  • high efficiency in application, practically a guarantee of the absence of fogging of glasses;
  • successful technology, which also allows you to protect the glass from possible damage;
  • a fairly simple application, which can be compared with sticking tinting.


If you decide to take such drastic measures, it is better to trust the experts and actually get a lot of interesting benefits. Firstly, a really effective protective film will be selected for you. Secondly, professional installation will be performed without any difficulties and wrinkles on the glass. So you can’t stick the film on your own.

We remove excessive humidity in the car interior

To get rid of the effect of fogging glasses, you need to control the humidity in the car. To do this, it is enough to ensure that water does not accumulate in the cabin, wet rags after wiping surfaces, snow from the feet of the driver and passengers. The more moisture there is in the cabin, the more difficult it will be to cope with fogging. Therefore, there are several methods to increase the efficiency of drying the interior:

  • remove all excess moisture from the passenger compartment, pour water out of the rugs and wipe them;
  • throw away all the rags that need to dry in the trunk of the car;
  • talk less, especially when there are four or five people in the cabin;
  • put several packs of table salt in a paper bag into the salon;
  • wrap some cat litter in a light cloth in an inconspicuous place.


As you can see, there are methods for getting rid of excess moisture. This is one of the most effective preventative options for fixing a problem. However, it is not always possible to absorb enough moisture to prevent fogging of the windows in the cabin. Most likely, you will have to additionally clean the glasses themselves, and possibly treat them with something special to avoid negative effects.

Other methods of getting rid of fogging glasses

One of the most effective solutions that works flawlessly is cleaning glass with a simple household product in the form of a glass and mirror cleaner. This allows you to clean the inner surface of the glass and fully provide the necessary conditions for the trip. With glass cleaning, you can eliminate the problem permanently. The following methods of dealing with such troubles are also distinguished:

  • correction of the cabin ventilation system, both inlet and outlet openings;
  • adjusting the direction of the damper, which controls the air flow from the air conditioner;
  • rubbing the glass with a mixture of glycerin and alcohol, which creates a protective film and prevents the glass from sweating;
  • installation of additional airflow to problem areas using small fans;
  • the use of other methods that are known in the modern information world.


Such methods are not always effective, but most of them help to eliminate the intensity of the problem. That is, it is quite possible that you will not get rid of the fogging of the glasses completely, but you will be able to eliminate most of this task. At least the windows will not sweat so much that it is impossible to drive normally and view objects on the road. We suggest supplementing the acquired knowledge with tips from the following video:

Summing up

Misted glass is a real problem of the winter and autumn period for the motorist. By applying the simplest of the above methods, you can completely get rid of the problem and get the necessary quality of car operation. Therefore, it is best to resort first to the most inexpensive and simple methods, and then move on to more complex ones if you cannot achieve the desired effect. You can simply wash the windows with detergent or apply a solution of alcohol and glycerin, try to reduce the humidity in the cabin.

If all simple methods do not help, it is worth moving on to more complex procedures. Apply a special solution to the glass or stick an anti-fogging film. So you can definitely get rid of problems, but these processes are much more expensive. Nevertheless, a motorist is sometimes ready to give a lot so that the windows in the car do not sweat. After all, this is the safety of the trip, which in the end can cost the health or even the life of the driver and passengers. How do you keep your car windows from fogging up?

Absolutely any driver, professional or novice, sooner or later, is faced with a problem when the windows in the car are sweating, they don’t always understand what to do. Sweating windows of your favorite car not only cause discomfort, limiting the visibility of the driver during the start of the vehicle, 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 the windows in the car fog up and how to deal with the difficulty by wiping the windshield with a rag or sleeve. Let's understand why the windows in the car sweat from the inside and how to fix the situation? First of all, you can use alarmauto-vrn.ru car interior care services - a protective coating for glasses and special compounds that treat car surfaces will significantly improve the situation.

Reasons why car windows sweat.

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

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

1. In the cool and winter season, the windows in the car are covered with sweat from a sharp difference in temperature and humidity between the car 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 condensate.

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

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

4. The windows of your car can also sweat in the event of a broken valve or sensor that regulates the normal operation of the valve flaps. Due to these problems, air does not enter the cabin.

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

6. Washing your favorite car - moisture gets inside the cabin, and he does not have time to dry.

7. A “cheerful” passenger who is in a tipsy state is also, albeit transient, the cause of fogging of windows in a car. Alcohol vapors absorb moisture and settle on the car windows in the form of condensate.

How to fix fogging on car windows.

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

1. Correction of the settings of the climate system of your car. Directed flow, included blowing warm air on the glass will cope with this. Also, the presence of an air conditioner will allow you to cope with the task in a few minutes.

2. The use of specialized anti-fogging equipment, or in other words, anti-fogging agents. The wide selection on the market today allows you to choose any to your taste, in the form of liquids, spray or wipes. The most famous are such as Ombrello VISIO, "Antituman", etc.

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

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

5. One simple step will help you deal with condensation on the side windows. You just need to slightly open the side windows, 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 misted windows. If you turn on only the stove, the air will circulate in a circle without eliminating the problem.

Wet weather and rain, the windows in the car sweat, what should I do?

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

3. Do not leave wet clothes, umbrellas in the cabin, dry the mats periodically.

4. Timely change or clean the cabin filter, as well as troubleshoot the valve or sensor that regulates the valve flaps.

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

In the winter season, the dilemma of what to do if the windows in the car are sweating, and how to deal with it, is especially relevant. Many modern cars are equipped with glass heating systems, which provide quick drying of the windows in the car.

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

If the windshield sweats from the inside, what to do with such a problem? Simple enough - so that the windows do not sweat in the car, the driver can purchase a special compound. It is very convenient to use, it is available in the form of a liquid and a spray, such a special tool is enough for 2 weeks of use.

The windows in the car fog up from the inside - how to deal with this 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.

It is necessary to apply a thin layer of shaving cream or gel on the glass, then wipe it with a rag or paper.

Surprising but true! Salt perfectly absorbs moisture, and in order to prevent the windows in the car from fogging up, it is necessary to place paper bags filled with salt under the windows. Salt will absorb all the condensate, and fogged windows will no longer be a problem for you.

This fruit is a real helper in the fight against fogging of glasses, it is not difficult to find it in any grocery store. We cut the lemon into two parts and wipe the car windows, wipe with a towel.

Many experienced drivers wipe the windows of their cars with a regular newspaper, which not only eliminates streaks and adds shine, but also perfectly absorbs moisture.

5. Ordinary soap!

In order not to sweat the glass in the car, it is enough to draw squares with soap in the corners of the windshield and wipe it with a rag. The soap forms a thin film on the window and protects the glass.

6. Self-made defogger.

The composition of such a kind of super-remedy includes ethyl alcohol and glycerin, all this is easy to purchase at a pharmacy within walking distance. The components are mixed in a ratio of 1:20, part of glycerin to 20 parts of alcohol. The mixture for convenience only remains to be poured into a spray bottle from a window cleaner.

Summing up

In the current article, we figured out why the windows inside the cabin sweat in the car, examined the most common reasons why this happens. Every car owner is interested in learning the basic ways to eliminate fogging of windows in a car. We examined the most popular among motorists. It is not necessary to run to the nearest automotive goods store, there is an opportunity to cope with folk remedies.

In general, it is quite easy and simple to solve the problem with sweaty windows in a car!

On the street - cold, slush, and the rain started again ... And in the car - dry, warm and comfortable. But as soon as the door slams behind the fourth passenger, they fog up and visibility is reduced to zero. We learn to deal with it.

Misted windows in a car are a rather serious problem, although discussion of this topic usually causes ironic smirks and remarks like “you need to drink less.” The deterioration of visibility most directly affects traffic safety. While the temperature is above zero outside, it is enough to wipe the windows with a napkin or just with your hand - just to reach out from behind the wheel. But with the advent of frost, any moisture on the glass turns into ice, which cannot be removed so easily. This means that the last autumn days are the time to eliminate the source of moisture penetration into the car and tidy up the heating and windshield blowing system.

Breathe less

An indisputable fact is that moisture, in contact with colder car windows, condenses and turns into droplets visible to the eye.

To fix the problem, you need to deal with the factors that cause it. Firstly, it is the increased humidity inside the cabin. First of all, moisture is contained in the air exhaled by the driver and passengers. Completely eliminate breathing, of course, impossible. But if people do not talk, the amount of air passed through their lungs (and humidified) will decrease. It is appropriate to say that the presence of drunken passengers actually activates the process of fogging the windows. There is an explanation for this: the exhaled vapors of alcohol, due to its hygroscopicity, “along the way” additionally absorb moisture from the body.

Another source of moisture is wet carpets, sound insulation, seat upholstery. Evaporating from the fabric, water saturates the air and immediately "transplants" to the windows. The owner is simply confused: he turned on the “stove”, and the fan, but it flows from the windows! And the thing is that the movement of warm air stimulates the evaporation process. At the same time, the owner of the car sometimes does not even realize that his car requires major drying. If the upholstery of the floor and the shelf under the rear window are “chronically” wet, then it’s time to take care of sealing the cabin in places where rainwater penetrates: along the glass seals, antenna outlet, wiper arms, etc.

In vehicles equipped with climate control, the air can be humidified because the condensate formed during its operation is not discharged to the outside through a clogged drain hole. In contact with the water lingering in the air ducts, the air passing through them “gets wet”, and moisture enters the passenger compartment. To disassemble the dashboard and clean the holes, of course, it will take time and money, but the transparency of the windows is worth it. However, this malfunction is rare.

Don't let water on the glass

One of the rules is not to allow moisture to settle on the glass. The regular ventilation system of the car is able to at least protect the windshield (and sometimes the front side windows). If blowing does not bring results, in modern foreign cars you need to check the condition of the cabin air filter. Quite often, it is its pollution that impairs ventilation, which is why the windows sweat intensively even on cars with the most advanced microclimate systems. In addition, sometimes jammed damper actuators of the ventilation system, which redistribute air flows, interfere with the free passage of air to the nozzles and glass.

Drivers of older cars, in addition to the main blowing system, often install an additional fan aimed at the windshield or rear window in the place most important for visibility. The elementary blowing of the windshield with cold air from the street, which enters through the rotary window (if it is provided by the design), also helps. Naturally, the air intake into the ventilation system when the windows are “sweating” must be carried out not from the passenger compartment, but from the street. The windows fog up intensively when the air recirculation system in the cabin is turned on.

To reduce air humidity, it is useful to turn on. In the cold season, if the design allows, it can be turned on in parallel with the “stove” - this is enough.

It has also been noticed that much less moisture settles on clean glass, so in winter, experienced drivers wash windows with warm water and soap or even pure alcohol. According to them, with an increased tendency to fogging, one such procedure is enough for 2-3 hours, depending on the size of the cabin and the number of passengers.

One can only envy motorists if the windshields of their cars are equipped with built-in electric heating. Naturally, both front and rear heating must be turned on at the first sign of moisture on the windows.

and glass

In the manufacturers' catalogs there are both liquid and aerosol products that prevent windows from fogging. However, the choice and application of "antiperspirants" for glass is a delicate matter. The fact is that some drugs leave a greasy layer on the glass surface - so noticeable that, touching it with your hand, you can then leave fingerprints on the seat upholstery. If such a product is applied to car windows through which the driver watches the road, streaks and glare will create very serious complications, especially at night.

At the same time, high-quality products used according to the instructions are completely invisible (therefore, they do not require removal at the end of the season). Even if four or five people are accommodated in an unheated cabin, such preparations do not allow moisture to linger on the treated glass. Oddly enough, it turned out to be quite difficult to find anti-fog glass products on sale when preparing the article, although autumn is in full swing.

Folk remedies

To protect windows from fogging and freezing, experienced drivers rub the glass with glycerin. However, when driving at night, this method must be used with caution, since the layer of glycerin on the glass creates glare.

In the old days, if the fogged glass began to freeze, the drivers rubbed the glass with salt wrapped in a rag. In frost of about 10 ° C, such a procedure had to be repeated from time to time. The method is bad because the glass remains wet, and salty moisture flowing under the dashboard and behind the door trim provokes corrosion. In the zone of action of the “stove”, the salt on the glass dries up, leaving white stains - “salt marshes”.

The most "harmless" folk way- Keep one of the windows open. But in this case, some temperature discomfort is inevitable.

The principle of operation of anti-foggers

Drugs work on the principle of change surface tension. Due to the low surface tension, the water-repellent film deposited on the glass prevents the formation of microdroplets and their retention on the glass surface, i.e. the settling moisture spreads over the surface of the glass in a thin even layer.

Such funds usually operate in two stages. First, the anti-fog agent cleans the glass (almost all brands have cleaning properties), and then the applied and rubbed layer of the drug creates protection against moisture. If the glass is dirty, the effectiveness of the defogger will deteriorate due to uneven film formation.

The problem of misted windows becomes especially relevant in the autumn-winter period, when the abundance of precipitation, coupled with darkness, creates problems for the perception of the situation on the road. Fogging the windows only exacerbates this problem. The cause of fogging lies in the temperature difference. In a warmer interior, moisture condenses on cold windows.

1. Newspaper


Lay newspaper sheets on the dashboard, cover the back seats in the car with them. The moisture present in the air will immediately be absorbed into the newspaper sheets - the windows will remain transparent.

2. Lemon


Use half a lemon to rub clean glasses, then polish them with a towel. From sweating, you can forget for a long time.


Toothpaste is a headlight protector. It won't work for windows. Lubricate the surface of the headlights with paste and wipe them with a rag. Clean headlights are the key to safe driving during the off-season.

4. Diaper


Probably the best one out of all of them. Several unfolded diapers in different corners of the car are a sure salvation from the humidity in the cabin and muddy wet windows.

5. Shaving cream


Apply a thin layer of shaving cream to car windows. Then dry them with paper or a towel. Shaving cream will create a barrier to prevent wet perspiration.

6. Coffee


Place ground coffee in a plastic bag with a small hole. Coffee not only absorbs moisture in the cabin, but also gives a pleasant aroma.

7. Potato


Cut the potatoes into several pieces lengthwise and wipe the windows in the car from the inside. After that, wipe the glass with a regular towel. The anti-fog protective starch film is ready.

8. Salt


Fill paper tea bags with salt and place them near windows. You can also make envelopes out of plain paper. The more salt there is in the car, the better the effect will be - as you know, it absorbs moisture brilliantly.
