How to adjust the ventilation system so that the windows do not sweat? The glass in the Kalina fog up from the inside what to do

Causes of fogging and icing of glass 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.

Nevertheless, while driving a car, drivers are often haunted by the problem of fogged up windows. It seems as old as the first created iron horse with a salon.

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

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

the windows in the passenger compartment are fogged up and covered with frost

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

It accumulates due to:

• rubber mats that do not absorb it. A similar property is possessed by their cloth brothers,
• a large temperature difference in the passenger compartment and outside the car during the rest of the latter,
• fullness of the car with passengers,
• incorrect adjustment of the warm air supply in the passenger compartment,
• temperature differences outside and inside the car during its movement,
• the presence of a person / people intoxicated or who drank alcohol the day before,
• as a result of an abundant amount of alcohol-filled sweets eaten 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: the reasons

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

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

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

Other causes of fogging in the car's interior are:

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

Why do the windows in the car sweat from the inside during the rain?

To answer the question, let's remember 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.
• So there is more water vapor in warm air than in cold air. But from interaction with cooler objects, for example, 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 get colder. Therefore, warm air in the cabin, colliding with them, condenses on their surfaces.

Why do the glass inside the passenger compartment of the Lada Kalina, Matiz Deo, Hyundai Solaris sweat a lot?

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

• poor air circulation between the passenger compartment and the trunk
• antifreeze leak
• radiator leak from the stove
• activation of the "recirculation" mode
• the presence of excess moisture under the mats of the driver and front passenger
• problems with the air vents in the trunk, for example, they are closed or filled up with something
• the cabin filter does not work well and needs to be replaced
• hangover passenger

The windows in the Matiz Deo salon "cry" because of:

• accumulating moisture under the rugs
• poor air circulation
• in winter and after rain due to temperature differences inside and outside the passenger compartment
• incorrect adjustment of the warm blowing of glass and interior
• manual adjustment of the deflectors, which you still need 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 obstructed ventilation holes in the trunk
• incorrect adjustment of the air conditioner turned on for heating
• switched off mode of air intake from the street
• accumulated dirt in the air filter

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

the side glass inside the car fogged up heavily in winter

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

• Install outdoor air intake from the moment the engine is turned on.
• Use an air conditioner, namely its cooling mode.
• Open the side front or rear window 1-2 cm while driving. In this case, the heating of the passenger compartment should also work.
• Check for moisture under the driver and front passenger mats. If present, wipe it off and place dry newspaper / paper underneath.
• Adjust the position of the deflectors, point them at the side windows.
• After turning on the car engine after 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 tip a couple of times a month during the colder months.
• Insulate the radiator for the winter, for example, with a piece of cardboard.
• Regular anti-fogging will help prevent fogging of the windows in the car. Apply it only to clean and perfectly dry surfaces. Repeat the procedure every 7 days.

If the windows are frozen, add the intensity of heating the passenger compartment. Reduce it when the frost is gone.

What kind of means, a solution for glass treatment, is needed so that the windows in the car do not sweat?

You need a so-called anti-fogger.

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

• sprays
• liquids
• special napkins

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

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

• Kitchen or sea salt. Wrap it in a cloth and wipe the glass 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 glass of the passenger compartment with a solution.
• Paper, newspapers, cardboard. Place a piece of paper underneath the driver and front passenger carpets. And be sure to regularly change it to dry. Also wipe the glass with paper.
• Shaving foam. Wash the inside of the windows and rub with foam. Wipe off the rest with a dry cloth.
• Tobacco. Break a few cigarettes and rub the inside of the clean glass with tobacco.
• A pack of salt in a paper box. Find a place for it in the back and lay it down. It will perfectly absorb excess moisture.

So, we examined the reasons for the appearance of condensation in the passenger compartment, including with the subsequent freezing of glass. Identified 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 windows in the cool and winter seasons. It is better to know about the causes and eliminate them in a timely manner.

Video: the reasons for fogging the windows in the car

Good visibility is one of the main prerequisites for safe driving. It is clear that the glass of the car, both side and windscreen, must always be clean. But what if the windows in the car fog up?

Why does the windshield constantly sweat from the inside: the main reasons

The windows in the car fog up from the inside due to the fact that the temperature in the cabin exceeds the outside temperature. As a result, moisture in the passenger compartment condenses on the glass. If the air humidity is high, then the windows completely cease to be transparent. That is why the windshield fogs up especially strongly from the inside in the rain (although this can happen in dry weather).

From the foregoing, it follows that in order to eliminate condensation in the vehicle interior, it is necessary to minimize the moisture content in the air. Its amount can be increased for several main reasons:

1. Water on rugs or damp shoes
2. A large number of passengers (a lot of water is released with breathing)
3. Wet salon

Most often, the glass in the car interior sweats because of this. The recommendations in this case are simple: you need to monitor the shoes and cleanliness in the car, and also, in case of fogging, wipe the windows. In addition, before accepting passengers, you should warm up the car. However, there are other reasons why the glass in the car perspires.

The cabin air filter is dirty

Misted glass can be a sign that the air filter needs to be replaced. If it is dirty, moisture simply cannot leave the car. In addition, air pollution in the passenger compartment appears, and when the ventilation is turned on, airflow is not felt. Experts recommend not to wait for such consequences, but to replace the element every 10,000-20,000 km.

Ingress of water into the salon

Moisture can enter the car not only through the doors, but also through the ventilation. All cars have drain holes under the hood. If they become clogged, then water will accumulate and enter the ventilation system. Because of this, the windshield sweats from the inside.

Damp soundproofing

The materials used for soundproofing in cars can absorb water well. This is especially often observed after driving through puddles or in rainy weather. To prevent the glass from sweating in the car, it is necessary to dry the material.

What to do if the glass sweats while the air conditioner is running

Quite often, motorists are faced with fogging windows when the air conditioner is running for a long time. In this case, moisture is already formed outside. In fact, this process is normal (again, there is a large temperature difference). Therefore, you should not worry in this case.

How to remove condensation

After the appearance of condensation, many motorists immediately turn on the stove or open a window. These methods do work, but this may not be enough. If visibility does not improve, wipe the windows diagonally (less streaks remain) with a clean cloth or tissue.

Anti-fogging chemistry

On sale you can find products that help get rid of condensation. They can be in the form of liquid or mastic, and are used both on the inside of the glass and outside. Anti-fogging must be applied to a dry surface and rubbed. After that, a transparent film will appear on the window, repelling water. In winter, you can use anti-ice products.

You can also make a DIY glass defogger. To do this, you need to mix glycerin with alcohol, and then apply the mixture to the window.

If the windows in your car are sweating, you can try turning on the stove. If condensation persists, you should use an anti-fogging agent in your car. It may also be necessary to replace the cabin filter (it is better to choose a charcoal filter).

Most often, the windshield fogs up from the inside in rainy weather. Therefore, it is advisable to take care of this problem in advance. Here's what you need to do for this.

• The condition of the interior should be monitored. It must be dry.
• Before you seat passengers, you need to warm up the car.
• You can use specialized tools. The main thing is that the anti-fogging agent is of high quality, otherwise stains on the glass are inevitable.
• It is necessary to periodically clean the car windows.
• If there is an air conditioner, it is advisable to turn it on and direct the air flow to the glass before driving.

Windscreen fogging is a real problem, especially for a novice driver. So why does the glass sweat? Due to the difference in temperature inside the car and outside. It is warmer inside the cabin than outside, because moisture condenses on colder glass.

One of the reasons for moisture condensation is people in the cabin. The air exhaled by passengers is abundantly saturated with moisture. Therefore, a trip in a large company often requires the driver to constantly adjust the airflow and adjust the climate system.

Another reason for fogging is. After poor-quality repairs, the air ducts from the climate system unit to the deflectors may not be installed correctly. Air conditioning system drain holes can also be damaged. As a result, condensation simply has nowhere to go, and it most likely enters the passenger compartment. And the more moisture inside the car, the more the glass sweats.

Finally, the windows can sweat due to the fact that the passenger is in the car, as they say, "after yesterday." As a result, a person's sweating increases and the pulse quickens. The exhaled air contains more moisture. And the car interior is a closed space, and here the air saturation with vapors occurs very quickly. By the way, the "fog" on the windows very much attracts the attention of the traffic police, who use it to identify drunk drivers.

How to fight?

The easiest way to combat fogging is to keep the air dry. To do this, turn on the air conditioner. It dries air very quickly. You can also change the air circulation in the passenger compartment by directing the ventilation deflectors to the glass, thereby heating the latter. Monitor your condition. If it is clogged or damp, it must be replaced, otherwise the glasses will perspire regularly.

Car chemistry manufacturers produce a variety of anti-fogging products: aerosols, wipes, liquids. These products form the thinnest film on the glass, which prevents moisture from remaining on the glass. All formulations are applied to a dry surface, otherwise they will not work.

There are also cheap anti-fog "glasses". Ten parts of alcohol are added to one share of glycerin and applied to glass. The old-fashioned method has a significant disadvantage. Such a composition leaves a greasy layer on the surface. At night, stains greatly impair visibility, glare appears.

Some even wipe the glass with tobacco.

There is also a special film that is glued, like when tinting a car. It is similar to the films used for the visors of motorcycle or racing helmets. But it is advisable to install it in a specialized service, otherwise bubbles will appear under the film, and the result will not please you.

In rainy autumn or winter, water or snow can enter the cabin. During warming up, water evaporates and condenses on the glasses. Therefore, it is very important to remove moisture from the passenger compartment. Shake off snow from your feet before getting into the salon. Clean your interior mats regularly.
