Here's another dug up on the vast expanses of the network:
It turns out that the most common cause of freezing of glass in the car interior is the lack of car owners' skills to properly use the heating system. Often, trying to heat up the interior of the car as quickly as possible, they move the air intake control lever to the "inside" position. And although at the same time, the air inside the car really heats up quickly, since the same volume of air is driven through the “stove” radiator, however, if car owners win in one, they lose in the other.
Unfortunately, in such a situation, there is an increase in air humidity, which is also enriched with exhalation vapor from those sitting in the cabin, fumes from shoes, rugs, etc., and this, as a rule, leads to fogging or freezing of the interior glass. Unfortunately, if you turn on the “stove” for heating at the maximum fan speed and temperature, then in such a situation this will not help much, since in the process of movement the car glass is constantly cooled by a stream of oncoming air.
Then the question naturally arises as to when the “stove” operating mode, called “from the inside”, should be used in the car. It turns out that the operating mode of the “stove” “from the inside” must be used for accelerated warming up of the engine, just when the car is standing and the heating system is working.
In order to achieve the absence of icing on the windows of the car by the time the movement starts, it is necessary to transfer the air intake lever when the engine is partially warmed up to the “outside” position. Partial warming up of the engine is considered warming up by 50-60%. The use of the “from the inside” mode with the stove not working is also allowed when it is necessary to exclude exhaust gases from the engine compartment from entering the cabin, or when increased smoke appears outside, which can occur in city traffic jams.
If the freezing of automotive glass occurs with the correct regulation of the air intake in the “outside” mode, then this means that there are malfunctions in the heating and ventilation systems. One of the reasons for this may be a break in the lever cable during air intake at a time when it is in the “inside” position.
It is also possible that the radiator is clogged, and for some foreign cars, the air filter of the ventilation and heating system. At the same time, there is a smaller supply of fresh air into the car interior, and the missing volume is sucked from the passenger compartment, while performing re-circulation. Fogging or freezing of car windows can also occur when a lot of moisture has accumulated in the cabin in the fleecy floor carpets, as well as under them.
During the operation of the "stove" there is a constant evaporation of the accumulated moisture. The presence of high humidity in the car interior may also indicate a violation of the tightness of window, door and other seals through which water could penetrate inside during rains. It is advisable to dry the interior by removing carpets, or during prolonged operation of the car's heating system. It is imperative to find and eliminate leaks, since as a result of the first thaw, excess moisture will again enter the cabin.
In order to maintain normal atmospheric pressure in the car interior when the “stove” is running, the design of the ventilation system of any car provides for the presence of an exhaust device. In this case, the air from the passenger compartment through special slots or trim enters the channel with a rubber valve, and then is removed outside through the hole, which is hidden under the decorative grille.
Unfortunately, some car owners who do not know the mechanism of the car's ventilation system clog this hole in order to warm it up for the winter. The result is a lack of ventilation with all the consequences that follow from this, that is, frosting of glass, moisture in fabric upholstery and rugs.

Causes of fogging and icing of windows in the car. Ways to eliminate them.

People are accelerating in their movements. And they want to do it with maximum comfort, without adjusting for weather conditions and other reasons.

Still, while driving a car, drivers are often haunted by the problem of misted windows. She seems to be as old as the first iron horse created with a salon.

Let's talk in more detail about the causes of this phenomenon and how to eliminate it.

Why the windows in the car sweat from the inside in winter and freeze: reasons

the windows in the car interior are fogged up and covered with frost

The main reason for the fogging of windows inside the car, followed by freezing, is excess moisture in the cabin.

It accumulates due to:

• rubber mats that do not absorb it. Their cloth brothers have a similar property,
• a large temperature difference in the cabin and outside the car during the rest of the latter,
• occupancy of the car with passengers,
• incorrect adjustment of the supply of warm air in the cabin,
• temperature difference outside and inside the car during its movement,
• the presence of a person / people in a state of intoxication or who consumed alcohol the day before,
• as a result of a plentiful amount of sweets eaten with alcoholic filler by one of the passengers or by the driver himself.

Why do the windows in the car sweat from the inside after alcohol when you drink: reasons

There is only one reason - the saturation of the air in the cabin with alcohol vapors, which act on water as catalysts, increasing them in volume.

Thus, the indicator of relative humidity in the passenger compartment of a car with a person who has consumed alcohol tends to its boundary value. And water vapor condenses on the glass surface.

Please note that fogging occurs not only after drinking alcohol on the day of a trip by car, but also after 2-3 days.

Other causes of car fogging are:

• eaten rum sweets in an amount of 10 pcs.
• a liter of fresh juice drunk in one gulp in the morning

Why do car windows sweat from the inside when it rains?

To answer the question, let's recall physics from the school curriculum.

• Air is made up of not only oxygen molecules, but also water. The latter tends to accumulate / decrease depending on temperature and contact with objects / objects.
• There is more water vapor in warm air than in cold air. But from interaction with cooler objects, such as glass, you see condensation.
• It turns out that when it rains, the temperature outside the car's interior drops, but inside it remains unchanged.
• Windows, being on the border of two spaces, also become colder. Therefore, the warm air in the cabin, colliding with them, condenses on their surfaces.

Why do the windows sweat a lot inside the car Lada Kalina, Matiz Deo, Hyundai Solaris?

There are several reasons for the fogging of windows in the cabin of the Lada Kalina:

• poor air circulation between the passenger compartment and the trunk
• leakage of antifreeze
• heater radiator leak
• switching on the "recirculation" mode
• the presence of excess moisture under the rugs of the driver and passenger in front
• problems with the air vents in the trunk, for example, they are closed or littered with something
• cabin air filter not working properly and needs to be replaced
• hangover passenger

“Crying” windows in the salon Matiz Deo due to:

• accumulated moisture under the rugs
• poor air circulation
• in winter and after rain due to temperature difference inside and outside the cabin
• incorrect adjustment of warm blowing of windows and interior
• manual adjustment of the deflectors, which still needs to get used to
• lack of proper regular glass care

Condensation on the windows in the Hyundai Solaris cabin appears for the following reasons:

• closed or blocked vents in the trunk
• incorrect adjustment of the operation of the air conditioner turned on for heating
• disabled mode of air intake from the street
• accumulated dirt in the air filter

The side and rear windows in the car fog up from the inside in winter and freeze: what to do, how to eliminate fogging?

the side glass inside the car is heavily fogged up in winter

To reduce and eliminate fogging and freezing of the rear and side windows of the car from the inside, use a few tips:

• Install the air intake from the street from the moment the engine is turned on.
• Use the air conditioner, namely its cooling mode.
• Slightly open the side front or rear window by 1-2 cm while driving. In this case, the interior heating should also work.
• Check for moisture under the driver's and front passenger's floor mats. If there is, wipe it off and place dry newspapers/paper underneath.
• Adjust the position of the deflectors, direct them to the side windows.
• After turning on the car engine after a rest, select the recirculation mode and after 5 minutes start the air conditioner to dry the air. Leave it to work for a quarter of an hour. Use this advice a couple of times a month during the cold season.
• Insulate the radiator for the winter, for example, with a cardboard sheet.
• Prevent fogging of windows in the passenger compartment will help regular treatment with an anti-fogging agent. Apply it only to clean and perfectly dry surfaces. Repeat the procedure every 7 days.

If the windows are frozen, increase the intensity of the interior heating. Reduce it when the frost disappears.

What kind of glass treatment solution is needed to prevent the windows in the car from sweating?

the owner of the car treats the windows in the cabin with a special anti-fogging aerosol

You need a so-called "anti-fogging agent".

Among autochemical cosmetics of a similar direction of action, there are:

• sprays
• liquids
• special wipes

Buy any product with this characteristic and wipe all windows with it once a week.

Folk recipes for glass treatment so that the windows in the car do not sweat

• Kitchen or sea salt. Wrap it in a cloth and wipe down the windows before parking your car overnight.
• Glycerol. Dissolve it in water and treat glass surfaces. Another recipe is 1 part glycerin and 10 parts alcohol. Treat dry, clean interior windows with the solution.
• Paper, newspapers, cardboard. Place a piece of paper under the driver's and front passenger's floor mats. And be sure to regularly change it to dry. Also wipe the glass with paper.
• Shaving foam. Wash the windows from the inside and wipe with foam. Wipe off any residue with a dry cloth.
• Tobacco. Break open a few cigarettes and rub the inside of clean glasses with tobacco.
• A pack of salt in paper packaging. Find a place for her in the back and put her down. It will perfectly absorb excess moisture.

So, we have considered the reasons for the appearance of condensate in the car, including the subsequent freezing of the windows. We determined ways to eliminate fogging inside the "iron" horse and listed the main preventive methods.

Nobody canceled the laws of physics, therefore we will not get rid of many uncomfortable situations in life forever. Unfortunately, the same applies to the problem of fogging glasses in the cool and winter seasons. It is better to know about the causes and eliminate them in a timely manner.

Video: causes of fogging windows in the car

Hello dear motorists! From the very beginning, we will not dissemble and admit that the freezing of car windows is not such a frequent occurrence. Fogging of windows in a car, especially in rainy weather, yes, it happens in almost every car.

But the freezing of windows in a car is a natural phenomenon that is characteristic only for the winter time of operation, and occurs for certain reasons.

We hope that it is not necessary to explain to the driver for a long time that the phenomenon of freezing car windows is directly related to the safety of both you personally and the safety of other road users.

Actually, therefore, the questions: the reasons for the freezing of windows in the car, how to prevent the windows from freezing in the car and what means of freezing to use, should be given a few minutes of your precious attention. Either for information or practical application acquired knowledge.

Freezing car windows - the reason is only one

The one and only natural cause of freezing of car windows is high humidity in the cabin. In combination with the low air temperature outside the car, this leads: first to fogging of the windows, and then to their freezing.

There is simply no point in describing the physical causes of air condensation and freezing of car windows. And here practical advice about how to minimize fogging and freezing of car windows, novice drivers will be more useful.

For information, it should be noted that the process of freezing windows depends on the car windows themselves.

What does it mean? The fact is that conventional glass (stalinite) is installed on serial cars. And there are also athermal glasses.

Glasses made of stalinite have high thermal conductivity, so they condense moisture on themselves faster and more.

Athermal glasses, on the contrary, have low thermal conductivity, and, accordingly, the low temperature overboard does not lead to such intense moisture condensation as with stalinite glasses.

How to reduce the humidity in the cabin in winter

Increasing the humidity in the cabin depends on us: drivers and passengers. And, of course, the reduction of factors affecting the increase in air humidity also depends on us. Namely:

• When driving in rainy or cold weather, by default, forced air circulation should occur in the cabin. In winter, of course, warm, and in the rain, cool or warm, it depends on your preferences. Airflow should be directed to the windshield and side windows.
• When landing in the cabin, you need to try to bring as little snow as possible on your feet and clothes.
• In the winter period of operation, it is recommended to use mats made of textiles. Rubber mats collect moisture in the form of puddles underfoot, and textile mats absorb it.
• If you have climate control in your car, then the problem of freezing car windows will be solved automatically, without your participation.
• In the morning, after starting the car, let the interior warm up, smoke a little on the street, remove snow or frost from the windows outside with a scraper, which formed during a frosty night.

How to prevent car windows from freezing during overnight parking

Let's start with the fact that any antifreeze agent for car windows is a short-term phenomenon. De-icer or defogger fluid will run out very quickly if applied correctly.

And according to the rules, the glass anti-freeze agent is applied after thorough washing of the glasses, in two stages. And it works within 2-3 days. Now calculate how much liquid from freezing glasses you will need for the winter.

Naturally, a reasonable question arises: how and with what to treat glass from freezing during winter parking? And the answer to this question will give us, as always, the people's automotive experience.

Ways to prevent the windows from freezing when parking the car:

• Five to seven minutes before arriving at the parking lot, turn off the stove in the passenger compartment and open the window a little.
• After stopping, open the door (doors) of the passenger compartment for a couple of minutes, this will equalize the air temperatures: inside and outside.
• In the parking lot, you can use the folk method: pour salt into the cloth and wipe it from the inside of the glass. Or from a spray bottle, spray a home-made mixture on the glass: 3: 1 water and vinegar (not essence). This helps the windows not to freeze from inside the cabin.

How to treat glass from freezing in the morning:

• By default, internal ice is removed by warm air from the stove, and at this time you are struggling with external ice.
• In order to remove the external ice (frost), there are special glass cleaners. But, why buy for a lot of money, an impractical amount of anti-freeze liquid, if you can make it yourself. To do this, you need the cheapest vodka, water and a spray bottle. Solution 2:1 (vodka: water). After all, the liquid for cleaning glasses from ice is made on an alcohol basis.
• After you process the outer part of the glass with a water-vodka solution, it remains to collect the melted ice with a scraper. By this time, in the cabin, the stove will already cope with internal frost.

Everything, you can go on the road without worrying that you will have a limited view due to frozen car windows.
