If you’re driving in winter, it’s important to keep your windows open as much as possible. This will help keep the inside of your car warm and clear of fog. However, if you can’t open your windows completely, there are a few ways to try to reduce the amount of fogging up. One way is to use a heat-resistant glove. Another way is to place a cold object on top of the window glass so that the fogging up won’t happen. Finally, you can try using a air-purifying cleaner on your windows before you drive away in order to remove any built-up particles from inside your car.
