How to Prevent and Eliminate Windshield Fog in Rain

Driving in the rain can be tricky, especially when fog forms on your windshield. This fog can significantly reduce your visibility, making it difficult and dangerous to drive. Fortunately, there are ways to both prevent and eliminate windshield fog when you’re driving in the rain. In this article, you’ll learn how to keep your windshield fog-free so that you can safely enjoy a clearer drive-in wet weather.

Prevention Tips

Several things you can do to prevent fog from forming on your windshield when it’s raining.

• Keep Your Windows Closed: One of the best ways to keep fog off your windshield is to keep your windows closed and use the air conditioning in your car (if available). This will help keep the air inside your car dry and prevent moisture from coming in through open windows and creating fog on the glass.

• Create a Ventilation System Inside Your Car: If you don’t have an AC system, you can still help reduce windshield fog by creating a ventilation system inside your car. Open both front windows slightly, then open all the other vents or openings around the edges of the window as well, but not too much that it lets the rain in. Then, turn on the fan settings for both front windows so that air circulates throughout your vehicle.

• Adjust Temperature Settings in Your Car: You can also help reduce windshield fog by adjusting temperature settings inside your car so that they are cooler than outside temperatures and cause condensation to form on surfaces other than the windshield. This will help keep moisture away from areas with direct contact with rain-splashed glass, reducing the chances of fogging up while driving in wet weather.

• Park Under an Overhang or Shelter When Possible: Finally, if you can, try to park your car under an overhang or other shelter when it’s raining outside. This will help protect your windshield from direct contact with the rain and reduce the chances of fogging up while driving in wet conditions.

Eliminating Existing Fogs

If you already have fog on your windshield when it’s raining, there are several steps you can take to eliminate it quickly and easily:

• Turn On Air Conditioning/Heating Set to Defrost/Recirculate Mode: One of the best ways to get rid of existing fog on your windshield is to set your car’s air conditioning or heating system on defrost/recirculate mode and turn up the fan setting so that warm air circulates throughout your car. This will help evaporate any moisture on the glass and clear away the fog for a clearer view while driving in wet conditions.

• Wipe Down Windows with a Microfiber Cloth and Glass Cleaner: You should also wipe down windows with a clean microfiber cloth and glass cleaner solution to remove any residue that may be causing fogging-up of the glass. Also read here How to Polish a Windshield.

• Turn On the Air Vents or Open Windows to Increase Circulation: Finally, you can also try turning on the air vents or opening windows slightly to increase air circulation inside your vehicle and help clear away any fog from your windshield.

Conclusion

Driving in wet and foggy conditions can be dangerous, but with the right prevention and elimination techniques, you can keep your windshield clear and fog-free for a safer driving experience. By keeping windows closed, creating a ventilation system inside your car, adjusting temperature settings, parking under an overhang or shelter when possible, turning on air conditioning/heating set to defrost/recirculate mode, wiping down windows with a microfiber cloth and glass cleaner solution, and turning on the air vents or opening windows slightly to increase circulation inside your vehicle – you’ll be able to prevent and eliminate windshield fog while driving in the rain.
