Ventilate like a pro
How you adjust the ventilation makes a big difference. Turn on the air conditioning, even in cold weather: the air conditioning removes moisture from the air. Leave the recirculation function off, otherwise you will just be circulating the same humid air all the time. Does your car have a dehumidification or defrosting function? Use it; it immediately directs warm, dry air towards the windscreen. Aim the vents towards the glass, and if necessary, also turn on the rear window demister – this will help to remove the mist much faster.
Clean windows fog up less quickly.
Dirt and grease on the glass cause water droplets to stick to it. So clean the inside of your windows regularly. A good glass cleaner works perfectly, but a mixture of water and a splash of vinegar is also effective. Avoid washing-up liquid; it can leave a greasy film that condensation sticks to particularly well. Anti-fog spray can also help reduce moisture build-up.
Unexpected tricks that actually work
There are a few lesser-known tricks that many people swear by. A simple hood or grille over the air intake on the windshield can prevent particularly humid outside air from being drawn in. A folded newspaper on the dashboard absorbs a surprising amount of moisture. Apply a very thin layer of shaving cream to the inside of the windshield and polish it streak-free – this works in the same way as an anti-fog spray. Is your car parked in a dry place? Leave a window slightly open to let moisture escape. Don’t leave wet sports bags or umbrellas in the car.
Driving with fogged windows is a recipe for trouble.
Driving off when visibility is poor is not only unwise, it is also illegal. You could be fined heavily for starting your journey without a clear view. If an accident occurs, your insurance company may also assume negligence, resulting in reduced or no payout. Furthermore, persistent moisture in your car can lead to mold, electrical problems, and dried-out or damaged window frames in the long term.
Maintenance that makes the difference
Are your windows constantly fogging up? Something could be wrong. Check your door and window seals for cracks or leaks. The cabin air filter (also known as the pollen filter) can become clogged over time and trap moisture. It’s cheap to replace, and the difference is immediately noticeable. If your air conditioning isn’t working properly or at all, it won’t dehumidify properly either. A check or inspection can fix this. Finally, make sure your water drains and trunk seals are clean to prevent rainwater from getting into your car.
Get clear vision quickly: here’s how to do it
Make it a routine: turn on the air conditioning, turn off the recirculation, direct the air flow to the windshield, and turn on the rear window defroster. Keep your car as dry as possible with rubber mats and moisture absorbers. Clean your windows regularly and use anti-fog spray or the shaving cream trick if necessary. Check the seals and cabin filter, and make sure your air conditioning is working properly. With this combination of habits, you’ll get going faster, see more clearly, and drive much safer in the winter.
