The inside of your windshield gets just as dirty as the outside. While the outside collects dust and debris, the inside gets covered by a faint translucent film which can be difficult to detect. Moisture loves nothing more than to get itself trapped in this film and generate a fog that takes longer to dissipate.

In order to keep the inside of your windshield clean, use an ammonia-based cleaner to wipe down the glass. Ammonia doesn’t leave streaks behind and leaves the surface of the glass looking spotless. You want to achieve a glass surface that’s free from film to prevent fog from taking over. If the inside of your windshield is tinted, you can use an ammonia-free cleaner to prevent damage to the film.

It’s not unusual for the air inside your car to become laden with moisture and cause the windshield to fog up. Setting the car to recirculate the air inside will only compound the issue. Switching the HVAC to use air from the outside will get the air to dry out as it circulates, even if the outdoor humidity is high. The air rushing through the vents will dry out quickly and stop fog from forming.

Some vehicles don’t have an effective external air circulator, but all is not lost. Crack the windows a little bit and let air come in from the outside to help dry out the interior.

This one might sound obvious, but it does more than eliminate the fog from your windshield. Turning on the defroster or defogger heats up the windshield more quickly and keeps the inside at a constant temperature. The warm windshield stays dry and prevents moisture from building up and frosting over. Monitor the state of the windshield and turn off the defroster once everything is warm. Getting the car to a steady ambient temperature also allows you to use the defroster less because the windshield stays at the same temperature as the rest of the car.

Coating the interior of your windshield can minimize or stop the formation of fog. Look for a product that cleans and leaves behind a repellent at the same time. The cleaning ingredient is specifically designed to work in concert with the repellent to provide the best possible protection against fog.

Windshield fog doesn’t have to be an inevitability. Follow these tips to help your car’s windshield from fogging up. You’ll spend less time waiting for the fog to clear and more time paying attention to the road.
