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 heated glass 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 are formed that 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 stops absorbing moisture and dust in the right amount, then condensation will also form on the glasses.
- Defective clean air valve. 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.
As a rule, solving technical problems in a car helps to get rid of the 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 the glass with it, then small scratches will remain on them, 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 step is to replace the 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 best result. To quickly get rid of perspiration, it is recommended to use special formulations.
Specialized defoggers
The easiest way is to purchase a 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 a 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 windows begin to sweat with enviable regularity, then it is best to carry out a complete diagnosis of the car. 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. Therefore, it is worth finding out all the possible causes of perspiration.

Misted glass is not only unpleasant. This seriously limits visibility and can lead to an accident due to the fact that the driver did not see another car or was unable to orient himself in a traffic situation in time.
One of the main causes of fogging of glasses is high humidity in the cabin. It may occur due to the fact that in snowy or rainy weather, the driver and passengers get into the cabin in wet shoes and clothes. They put wet umbrellas on the rugs. Moisture can also get through the stove from melted snow near the engine compartment. Yes, and people in the cabin exhale water vapor along with the air, which condenses on the windows.
How to deal with fogging glasses?
First, you need to make sure that water does not accumulate on the salon rugs. Therefore, shake off the snow from your shoes before you sit in the salon. And if moisture still accumulates on the rugs, it should be poured out. It is easier to do this without spilling some of the water on the upholstery if the rubber mats have a high side. Keep this in mind when buying new car mats. In winter, it is better to use rubber carpets. They, unlike pile ones, are better cleaned from water, snow and dirt.
Also, before driving, sweep away snow that accumulates on the ventilation grill located between the windshield and the hood. After the engine warms up, this snow will melt and moisture will go straight into the ventilation system, and from there into the cabin.
You can use anti-fogging agents that are sold at any auto shop. This composition prevents moisture condensation on the glass. It must be applied in advance to the cleaned, dry inner surface of the glass.
What to do if the windows are already fogged up?
Open the air recirculation damper and turn on the air conditioner. It dries the air, so it's the most effective and fastest way to get rid of fogging.
- good visibility. This is especially true in the off-season and in winter, when precipitation and darkness create natural problems for the perception of the situation on the road. And at the same time, most often motorists are faced with the problem of fogging windows.
The main reason for fogging windows is. In a warmer interior, moisture condenses on cold windows. Therefore, you can fight fogging by warming up the windows and drying the air - often this happens at the same time.
Here we give some simple tips on how to keep windows transparent.
Correctly set up climate control systems
At the first sign of fogging, you need to select the window blowing mode, direct the air flow from the deflectors to the windows and slightly increase the temperature. If the car has air conditioning, then it should dry the air in a few minutes. You just need to be sure that the internal circulation mode is turned off. If the climate system does not cope well with warming up and drying the air, you need to check the cabin filter - it could absorb too much moisture, and in wet weather it does not have time to dry out, or it's just time to replace it.
Treat glass with special products
There are many different anti-foggers on the market - liquids, aerosols, wipes. The principle of this autocosmetics is the same - the properties of surface tension change. The solutions create the thinnest film, from which the smallest particles of water roll off, forming drops that do not interfere with the view, or, conversely, the water remains on the glass, but lies in a transparent layer. Apply the product to clean and dry surfaces, and repeat the procedure as needed. You just need to find a drug that suits you according to the method of application, the smell and the result.
Treat glass with "folk methods"
The problem of fogging has been around for a long time, so drivers had time to find several options for window treatment using improvised means. One of the most popular is applying a solution of 1 part glycerin and 10 parts alcohol. If you use only glycerin, the glass will become greasy and at night there will be strong glare in the divorces, which impair visibility. Some advise wiping windows with newspapers - printing ink contains substances that create the same film as when using auto chemicals. Another tip is to rub the windows with tobacco from ordinary cigarettes.
Anti-fogging films
A cardinal and durable solution is to cover the glass with a special film, similar to that used for optics, motorcycle helmets or commercial equipment. It is applied in the same way as a tinting film - and it is better to trust professionals in this matter.
Remove excess moisture from the interior
Often in winter and in wet weather, water or snow gets inside the car. When the interior begins to warm up, the liquid evaporates and settles on cold windows. To reduce this effect, excess moisture should be removed. Sometimes you need to remove puddles or ice from the rugs, and if there is already a lot of water, put newspapers under your feet and throw them away when they are soaked. In the case when even with a little rain it becomes wet in the cabin, you need to check its tightness - the departed seal can be a source of not only high humidity, but also premature corrosion. No need to store rags that were used to wipe wet surfaces in the cabin - put them in the trunk or under the hood. Reduces humidity salt in a paper bag that can be put on the back seat. The effect will be better if the packaging was previously dried in heat.
Don't chat
The source of moisture is very often the people inside. The air they exhale is much warmer than the surrounding air and saturated with moisture, so when traveling with a large and noisy company, the driver now and then needs to reconfigure the climate in the cabin. If the equipment can not cope, then you can ask the passengers to just be silent for a while, for the sake of their own safety.
Check interior ventilation
It's rare, but sometimes it happens. After a rear-ended car, special ventilation valves can be sealed. In this case, the air circulation calculated by the engineers does not occur. Another variant of the same problem is an excessive amount of things in the cabin and trunk. The solution is to check the throughput of the air ducts, having previously studied their location according to the instructions. Clogged drain holes in the air conditioning system can also be attributed to the same problem. Standing water is simply blown into the cabin, and the situation can be corrected by simple cleaning.
If the car windows sweat without objective reasons, this may indicate a malfunction in the engine cooling system. The vapors formed from overheating enter the cabin through the ventilation system. In this case, it is better to turn to professionals.
One of the most common causes of windows fogging up is passengers on the eve of a trip. The exhaled vapors of alcohol, due to its hygroscopicity, additionally absorb moisture from the body, and it settles on the windows. This explains the increased interest of traffic police officers in such vehicles. You can deal with such fogging in the usual ways, but it is better to advise passengers not to abuse it before the trip.
