With the change of season to autumn and winter, as well as the onset of the accompanying cold weather and an increase in air humidity, all drivers are faced with such an unpleasant problem as fogging up the windows in the car. Not only does this phenomenon quite strongly affect the comfort of all passengers of the car and its driver, but the view is also greatly limited, and this can be really dangerous. For these reasons, it is necessary not only to understand why the windows in the car are fogged up. What to do in such situations is no less important knowledge.

Causes of fogging glasses

So, the question of why the windows in the car fog up is considered one of the most topical when the temperature outside the window starts to drop. There may be several reasons for such a phenomenon, and it is very important to know them, as well as to be able to resist in every possible way and be fully armed at any moment.

It's not good to constantly wipe the window with a cloth as soon as it fogs up. First of all, this is not very effective, and secondly, this method is very difficult while driving and entails the creation of an emergencysituation.

Human factor

We all noticed at least once that the more people there are in the car, the more the windows in the car sweat. This process is easily explained by the simplest knowledge of physics. The fact is that a person's breath, compared to the air temperature on the street and even in the car itself, is warmer. Therefore, when several people breathe inside the cabin, warm and cold air flows collide, and condensation appears on the coldest parts of the car, that is, on the windows, which is the settling of very small particles of water. This means that the more passengers in the cabin, the higher the percentage of moisture from the breath and the more the windows in the car sweat.

Temperature difference outside the window and in the cabin

Another very significant factor is the difference in air temperature outside and inside the car. Condensation also forms here, but the cause is no longer human breathing. In winter, the windows in the car fog up due to the fact that cold air flows from the street and hot air from the passenger compartment collide on the glass, as a result, the same phenomenon of moisture condensation occurs. Outwardly, it looks like foggy glass, blocking our view and causing a lot of trouble.

Air alcohol content

As many have already guessed, we are talking about people inside the car who drank alcohol. In this case, there are alcohols in the human breath, which, getting into open space, mix with oxygen molecules andreact with them. Alcohol in such situations is an active absorbent and is able to actively absorb moisture, settling on all surfaces, including windows, so that in this case fogging can occur even in summer. So there is a simple answer to the question "if the windows in the car are fogged up, what to do" in such a situation. Just ventilate the interior.

Clogged air filters

In the case when your car windows are fogged up, you don’t know what to do, and what could cause this phenomenon is also unknown, clogged air filters in the cabin may be to blame. With such a problem, the air inside does not circulate, and at the slightest resonance of temperatures inside and outside, moisture also settles on the windows. The way out of this situation is also quite simple, just send your iron horse for maintenance, where the problem of filter clogging will be eliminated, and unpleasant fogging will go away on its own. True, the above reasons should not be forgotten anyway.

Solving the problem of fogging windows in the car

As with the causes of fogging windows, the solutions here can also be different. Some of them are not very effective, but now we will look at the most radical methods of struggle that will allow the driver and his car to feel great at any time of the year.

So, as mentioned above, the windows in the car fog up a lot in winter, and this happens for obvious reasons. So at this time of the year, one of the most effective methods of struggle isserviceable stove, air conditioning and clean air filters. Thus, before each trip, try to turn on the air conditioner for a few minutes, which, as a rule, allows you to dry the air in the cabin a little, which prevents condensation. If the car is not equipped with air conditioning, just turn on the stove and open the air filters, the car will be ventilated and the air will become drier, which will give the desired effect. A more effective action would be to direct air flows from the air conditioner or stove directly onto the glass, this will greatly speed up the process.

Chemical control method

Another fairly effective and practical method for every driver. It involves the use of special washer fluids, popularly called simply anti-fog.

If the windows in the car are fogged up, what to do, you will understand as soon as you buy the appropriate product and read the instructions for use. However, it is still worth saying that anti-foggers differ in the method of action and are of three types:

• Specialized liquid, which, after careful processing of the glass, forms an invisible film that prevents any moisture from settling on the glass.
• There are also liquids and aerosols that, once applied to glass, can repel moisture.
• Anti-foggers in the form of ointment or cream are the third option for chemical treatment, after which you will not think about why the windows in the car fog up. This type of wrestling is the most expensive option of all.the three mentioned, however, one such treatment is more than enough for 2-3 trips even in heavy autumn rain, while the first two options will have to be applied again each time.

So, we have considered the most effective methods of dealing with fogging of car windows, and each car owner received a clear answer to the question of why the windows in the car fog up, which means that no bad weather is now scary for you.
