It’s not about vodka: what do fogged car windows say
In winter, car windows are actively misted from the inside. Creating trouble while driving and causing questions from traffic police inspectors. Moreover, this phenomenon can occur not only in old “wheelbarrows”, but also in absolutely new ones with their state-of-the-art climate control systems. Why is this happening and is it possible to fight such a scourge? The AvtoVzglyad portal addresses the problem, debunks myths and offers solutions.

There is a persistent misconception that the windows fog up from the inside because the driver has actively consumed alcoholic beverages. And it is on this basis that traffic police inspectors catch violators of a healthy lifestyle in the stream. However, this is not entirely true. Yes, in theory, a drunk driver’s glass can fog up more. But only because when drunk, body temperature rises and breathing speeds up. This allows more moisture to enter the cabin. But not so much that it could unequivocally identify a lover of spirits.

So this phenomenon has nothing to do with a sober or cheerful lifestyle. In addition, immediately after starting the engine, cold air is sent to the glass, the moisture of which inevitably condenses on even colder glass. And even an attempt to wipe it has practically no effect: the icy patterns mockingly quickly return to their place. But windows can also fog up in a warm car, which can have various causes. For example, the filter of the ventilation system is clogged. This greatly reduces the intensity of the airflow and also reduces the amount of heat received by the glass. Because of what they cease to heat up effectively and turn into an ideal environment for the accumulation of condensate.

The problem may also be related to a climate control malfunction. Which can often incorrectly regulate the temperature of the air streams. And this problem is very common. The same Land Rover has been repeatedly seen in such annoying flaws. It’s not worth talking about Chinese automakers. Yes, and Kia, however, had no problems with the windshield, but only with the driver’s door glass. Where else does moisture come from? Unfortunately, in winter there is always an excess of water in the car interior.

We have already said that a person releases a large amount of moisture in the exhaled air. And since we breathe directly into the windshield, the problem is simply unavoidable. In addition, in winter there is constant water on the floor of the car. And after we direct the flow of hot air to the leg area, it begins to actively evaporate and settle on cold surfaces. And this is glass. Of course we should not forget the technical condition of the air conditioner. If he can’t remove moisture from the indoor air, then you should think about diagnosing and repairing it. Fogged windows can therefore be caused by technical problems.

But there’s one more thing. Over time, an almost imperceptible film of dirt forms on the inside of the car’s windows. It is she who actively attracts moisture and creates a beautiful, but unpleasant effect of icy patterns. Therefore, the AvtoVzglyad portal recommends carefully checking the cleanliness of the inside of your car windows and not being lazy to wipe them at least once a week. However, this should only be done after the car and interior have fully warmed up. And with the use of special detergents.

After that, it is necessary to treat the surface with a moisture repellent. Such processing will not be enough for a long time, but you will be spared problems with freezing or fogging of glasses for a while. But if it’s particularly cold outside and you’re driving fast enough, the windows can still mist up because they’re cooled too much by the oncoming airflow. In this case, you just need to reduce the speed.
