If you own a car or have ever been inside one, you have probably seen the phenomenon where the glass windshield and the windows get fogged up at certain times. This fogging up occurs when hot air comes in contact with cooler air. Usually, it is the hot air from outside the car that meets the cold air from an air-conditioned vehicle, but, it can also occur when the cold air outside meets the hotter air of a vehicle. While fogging takes place over the entire body of the car, it is the windshield and windows where it can be seen the most and can create dangerous driving situations. Most people simply get out and wipe the fog away but that doesn’t keep it way which means you will have to get out of the vehicle every time the glass gets foggy. So, how to remove fog from car glass more effectively? Here are some helpful methods.

As described earlier, fogging occurs when different temperature air meet and form condensation on the windshield. During the scorching summers in India, there is nothing like escaping into an air-conditioned car. However, when the hot air from outside meets the cooled surface of the glass windows and windshield of the car, it immediately condenses and creates a layer of fog which forms on the outside of the windshield. Normally, the fogging that occurs in the summer is a lot easier to remove and here are some tricks you can use.

Although the cool air inside the car might feel exquisite in summer, it can be quite dangerous while driving. If you want to reduce the amount of fogging on your windshield, try and reduce the power of the air conditioning. When the temperature is increased inside the car, the air will begin to match the air outside and stop fogging quickly. What you can also do to stop your car from fogging up is to open a window a little bit to allow the outside air into the car. This will not only balance the temperatures quicker, but it will also allow you to keep enjoying your cool breeze.

Now that you know the fogging in summer is on the outside, you can easily get rid of it by simply turning on your car’s windshield wipers. Condensation is basically water that forms on the surface of your windshield and your wipers are designed to get rid of water, right? If you feel that the wipers are making the windshield worse, spray some cleaner and turn the wipers onto a lower setting so they clean the glass as well.

For all those people who are used to the summer heat and would rather put safety above comfort, the fastest and easiest solution to defogging your windshield is to open the windows. As soon as you find your windscreen and windows fogging up, roll down the windows to your preferred height and allow the outside air to fill the inside of the car. This will keep the inside of the car at the same temperature as the outside and stop fogging completely.

Opposite to what happens in summer, in winter, fogging in your car happens when the cold air from outside meets the warmer air inside the vehicle. This is when condensation occurs inside the car and causes the windshield to fog up from the inside. Winter fogging is a lot tougher to remove but there are a few ways to keep your visibility clear while driving.
Also known as the “Fresh Air Mode” button located on your dashboard, this is one of the easiest and quickest ways to defog your windshield in cold temperatures. The button has a car with an arrow that points into the car. Once turned on, this feature pulls in fresh air from outside but does not lower the temperature inside the car. Rather, the temperature is gradually balanced and the fog across your windshield will disappear. You will have to make sure that the “Recirculation Mode” is turned off which is the button with a car and a circular arrow inside it. This function recirculates the air inside the vehicle by closing the air ducts in front.
This might not be the best option, especially for those who try and stay away from the cold. If your windows are fogged up, you can simply lower the temperature inside the car to match the temperature outside. Either you can decrease the air-condition temperature or increase the fan speed to lower the temperature inside. Once the temperature is reduced, the fogged up glass windows and windshield should clear out. However, you will need to carry an extra layer of clothing to keep yourself warm.
For those who really know their cars, they will know that the button with a box and three squiggly arrows pointing upwards is known as the defogger button. This button is extremely useful for those vehicles that have to take on some of the coldest climates. Once activated, the defogger button sends air straight to the windshield. This air matches the temperature of the surroundings and reduces the fogging. Some cars come with defogger buttons for the front and rear windshields.
If you want to assist the above-mentioned methods and help prevent fogging up in the future, there are some handy tips you can put to use with easily-available products that are probably found around your home right now. One of the first things you can use is a dehumidifier bag or a couple of them and place them around your dash near the windshield. These bags are filled with silica balls that absorb moisture from the air. If you can’t find a dehumidifier bag, you can fill a handful of silica balls in a sock and place it around your car.
Shaving foam is another great product that can prevent fogging up. To apply the shaving foam, take a handful and spread it across the glass with the help of a clean cloth. Let the foam sit on the windshield for at least 2 minutes before you take another clean, dry cloth and wipe the residue off. This forms a protective layer above the windshield and prevents moisture from collecting on the windshield.
So, next time you are faced with a fogged up windshield or windows, you can easily use one of the above-mentioned methods or the products listed here to ensure that you always have clear glass windows and windshields. Driving with 100 percent visibility is extremely important and these tips and tricks will give you just that for a safer drive every day or night.
