If activating the air conditioning is often the first instinct to eliminate fog on the windshield, another button in your cabin would actually be twice as effective.
In winter, the battle against fog and frost can turn every morning start into an ordeal. And on the roads, there is no question of neglecting visibility. So, for everyone’s safety, here’s how to combat stubborn fogging in record time.
Indeed, when the mercury drops, mist regularly appears on car windows. When humid cabin air comes into contact with the colder windshield, moisture condenses on the glass, creating a hazy layer that prevents you from seeing properly while driving. Most vehicles are equipped with a defogging system which, in theory, is supposed to put an end to the problem in just a few seconds. You can also activate the air conditioning on full blast to clear the fog more quickly… However, even with these options, the wait can be long before you see a perfectly clear windshield. That’s why, when looking into the matter, a car dealership based in Crewe, England, realized that another function of your car could combat fogging, in no time.
In a Youtube video, Sam, spokesperson for the Swansway Motor Group dealership explained: “No air conditioning, well that’s not a problem. Some vehicles don’t have air conditioning or the function is broken or disconnected. To remedy your windshield fogging, simply roll down all the windows of the car.” In fact, by pressing the switch dedicated to opening the windows, this will immediately cause an exchange of air. The humid air in the passenger compartment will be replaced by dry outside air. “This allows outside air to enter the vehicle, helping to reduce fogging and getting you started twice as quickly.”, specifies the expert. Not a very pleasant technique when it’s cold outside, but which has the merit of resolving the problem quickly. Please note that this method should not be applied when it rains.
Finally, know that there are effective products, sometimes little known, to avoid driving with fog on your windshield. You will find, for example, car air dehumidifiers, to absorb humidity, or even an anti-fog cushion to place on the front of the car. Also remember to check that the seals on your windows which must be in good condition.
In addition to classic defogging in winter, some advice is emerging on social networks regarding cleaning windshields, which will help prevent the appearance of fogging. First, to make it easier to see traces and dirt, park your car in the shade. The sun may prevent you from seeing the condition of the glass clearly. Then, very often the windshield wipers go by the wayside when cleaning. Also make sure to wash and dry them properly. As for the material used, choose microfiber cloths. These will prevent any scratches. The squeegee can be a good option to reach the least accessible places.
