This problem is faced by many motorists who start their journey on the road. If in the summer its occurrence is unlikely, then in other seasons the appearance is far from rare, and besides, it is very intense. It's about the fact that the windows in the car are sweating. What to do in this case, an elementary knowledge of physics will tell.

If there is none, then you will have to get acquainted with such a phenomenon as condensation, and its causes. Let's figure out from this point of view why the windows in the car sweat, what to do with fogging, which is not only annoying, but also reduces the level of visibility of the world around us.

Physics of the phenomenon

Water vapor contained in the air of the machine comes into contact with the glass. If it is colder outside than in the car (we are talking about the autumn-spring seasons, as well as winter), moisture, in contact with the cold surface of the glass, will cool sharply, passing from a gaseous state to a liquid, and, as a result, settle on the glass inthe form of tiny drops of condensate. The fogging of windows in a car will be more intense if there are a large number of people in it, with one driver inside the car, this process will be slower.

That is, in addition to the moisture that could enter the interior of the car while it is in the garage or just stands with open windows on the street during rain, moisture will accumulate in the cabin, which comes out when a person breathes. Naturally, if the temperature in the cabin is similar to that on the street, there will be no difference, and moisture will not settle. But this is the way out. What can you do to keep your car windows from sweating and still stay warm?

Preventing the possibility of moisture getting into the cabin

You need to understand where the water comes from in order to avoid further saturation of the car interior with it. This primarily affects the process of sweating glass in the car. What should be done and what should be avoided so that moisture does not accumulate in the cabin in large quantities?

Cold seasons are characterized by the presence of snow and rain. These precipitations, which get inside the car with shoes and wet clothes, also negatively affect the level of humidity. Of course, you will not be able to undress or change clothes every time you get into the car. Fighting wet clothes is unrealistic, but it is possible to at least alleviate the degree of moisture in floor mats by simply placing a newspaper under them, which will absorb excess moisture from your shoes.

When you wipe with a clothglass before you travel, remember that it also remains water, and it will evaporate from the cloth as the air in the cabin warms up, returning to the windows again. To avoid this, keep the rag somewhere in the trunk.

Poor-quality rubber door seal also causes the windows in the car to sweat. What to do in this case is probably clear to everyone. All that needs to be done in this case to minimize the amount of moisture in the cabin is simply to replace the seal with a new, high-quality one that will fully perform its functions.

An interesting way to get rid of excess moisture in the cabin

You will need a regular pack of s alt. If it is opened, it will easily absorb excess moisture. Use this method or not, decide for yourself, based on, for example, how smooth the roads are in your region or in the places where you most often appear. Otherwise, by trying to fight one problem with this method, you will end up with a product that helps you deal with moisture spreading throughout the car, creating new problems with cleanliness.

These were simple methods for removing excess moisture, especially without extra costs. Elementary minimization of moisture and a little finance. There are also tools that will require a lot of money, but will more effectively help solve the question of why the windows in the car are sweating. What if the newspaper, s alt and other budgetary ways to reduce moisturenot helping?

Install high-quality ventilation and air conditioning

Filters that are available in the air conditioner, of course, can dry the air. But at the same time, you should monitor their cleanliness and degree of deterioration. The new air conditioner will do its job as well as possible; as soon as you notice that it does not do its job as it used to, this is the first sign that you need to clean or replace the filters.

Ventilation should be done as follows. If you can switch the device to the window blowing mode and at the same time increase the blowing speed itself, as well as the temperature of the air that will exit the heating element, you can dry the windows and remove moist air through the ducts. If this does not help, you need to monitor, for example, how clean these very air ducts are.

There are some other tools that will help to cope with the moisture on the windows. What to do if the windows in the car sweat, despite all the measures taken? This, of course, is unlikely if you have followed all the previous recommendations well.

Processing the glass itself

What can I do to keep my car windows from sweating? For this, various anti-foggers are suitable, which are sold in the form of sprays, wipes or liquids. The effect of these products is that they create a film on the surface of the glass with such a surface tension that moisture will simply flow down or accumulate in the form of single objects. If you financeallow you to buy such a mixture, then do not bother; if you want to make such a tool with your own hands, without relying on "any chemistry", then you can mix one part of glycerin, which can be bought at any pharmacy, with 10 parts of alcohol, which can also be purchased at any pharmacy. The smell of the mixture is specific, but no less than when using another folk method - rubbing glass with tobacco. Also, folk methods say that you can rub the glass with a newspaper or just perfectly wash and dry the surface of the glass from the inside.

Anti-fogging film and heated windows

If you rub the glass with a newspaper or a mixture of glycerin and alcohol more or less regularly, then the film can be bought once, and it will last much longer.

The most expensive and at the same time the most effective way is to install spiral electric glass defrosters, which were previously most often used for rear windows, and now there is a trend to install them even on the windshield.
