Monsoon 2024: How To Remove Fog From Your Car's Windshield

Fogged-up windshields can significantly impair your driving experience, especially during rainy conditions when visibility is already reduced. This fog forms due to the temperature difference between the car's interior and exterior, resulting in condensation when warm air meets a cold surface. While common during rains, fogging can also occur in summer and winter. Here are several methods to defog your car's windshield.

Use the defog button

Nowadays, even the base model of a car is equipped with a dedicated button to defog the windshield. Some cars even have defoggers set up for the rear windscreen. Just pushing the button sends air straight to the windshield. This allows the air to match the temperature of the surroundings and reduces the fogging.

Crank up the AC

During the monsoon season, the cold rainwater hits your windshield and turns it cold. On the other hand, the temperature within the car may be warm, which causes condensation on the inner surface, resulting in the windshield getting fogged up. The first thing you must do is gain some immediate visibility by wiping it with a lint-free cloth. You can then proceed to turn your car's AC to a colder temperature to match the temperature on the outside. This will cause the fog to vanish and is one of the best tips to defog a car during rain.

Lower the window

Agreed! This one's of no use when it's raining but if you're looking for tips on how to remove fog from a car's windshield irrespective of the weather, lowering the windows is a good option. When air from the outside suddenly fills up your car's interiors, the temperature inside starts matching up with the temperature outside thus reducing the fogging of the windshield.

Recirculate the air

This is one tip that's incredibly useful during the winter. Every car has the facility to either keep taking fresh air from the outside for the AC vents or recirculate the air that's inside. Use this button to allow outside air to enter the vehicle and balance the overall temperature and reduce the fogging on the windshield.

Use silica gel

The fog inside your car is nothing but condensed water vapour as mentioned earlier, which is also called humidity. If there's no humidity in your car, there won't be any fogging to worry about. Several companies sell dehumidifiers that can run on the 12V power outlet of your car. However, a much cheaper method is to keep a pack of silica balls on the dashboard to absorb all the moisture from the car's interiors. Keep checking this pack for its level of wetness since that's how you'll know it's time to replace it.

Now that you know how to remove fog from a car's windshield irrespective of the kind of weather you're driving in, you can ensure a safe drive for you and your loved ones.
