Condensation on the inside of the car
A practical guide to removing condensation from inside the car and preventing it from coming back.
Condensation on the inside of the car is a classic winter and autumn problem. It happens when moist air meets cold glass, but poor cleaning, wet mats and incorrect climate control make the issue much worse.
What you need to know
- Moisture in the cabin is the main cause of interior condensation.
- Clean windows fog up less than dirty windows with a film on the inside.
- The correct airflow and temperature give you clear visibility faster than simply turning everything to maximum.
Typical situations
| Situation | What you should do | Common mistake |
|---|---|---|
| Cold morning with wet floor mats | Use warm air on the windscreen and reduce the moisture in the cabin. | Starting to drive before the side windows are clear. |
| Several people in the car | Expect faster fogging and adjust the ventilation early. | Waiting until the windows are already covered. |
| Short city trips through winter | Dry and air out the car regularly to prevent moisture build-up. | Ignoring the problem because the trips are short. |
Common mistakes
- Wiping a small opening with your hand and driving on.
- Forgetting the rear window and side windows.
- Underestimating how much moisture wet clothes and mats add to the cabin.
