Driving in cold or wet weather often leads to foggy windows, reducing visibility and making journeys hazardous. But motoring experts have shared a clever trick to stop condensation forming on your windscreen and side windows almost instantly.
The Science Behind Foggy Windows
Condensation occurs when warm, moist air inside the car meets the cold surface of the glass. This is especially common in winter or during rainy conditions. While many drivers rely on air conditioning or heaters to clear the mist, there’s a quicker and more efficient solution.
The Expert-Approved Hack
According to driving professionals, the key is to adjust your car’s ventilation system correctly. Here’s how it works:
- Turn on your car’s air conditioning (even in winter) to remove moisture from the air.
- Set the airflow to direct air onto the windscreen and side windows.
- Use the recirculation mode sparingly—keeping it on for too long traps humid air inside.
- Crack open a window slightly to allow fresh, dry air to circulate.
Why This Works
Air conditioning acts as a dehumidifier, stripping moisture from the air before it reaches the glass. Combined with proper airflow direction, this method clears fog in seconds and prevents it from returning.
Bonus Tips for Fog-Free Driving
- Keep a microfiber cloth in your car for quick wipe-downs.
- Apply an anti-fog treatment to windows for longer-lasting results.
- Avoid leaving wet items (like umbrellas or coats) in the car overnight.
This simple adjustment could be a game-changer for drivers battling foggy windows during the colder months.
