Dealing with a Foggy Windscreen
In the cooler Canterbury months it’s not uncommon for your cars windscreen to steam or fog up on the interior. As I’m sure you’ve experienced this obstructs visibility making it difficult if not impossible to drive.
The fog is basically tiny droplets of water that condense on the cold surface of the windscreen. The air inside your car contains moisture from your breath, pets, and any wet items you may have. When this warmer moist air comes into contact with the cold glass of your windscreen, it cools down releasing some of its water vapor which sticks to the glass forming a fog. This is because the cooler air can’t hold as much moister as the warm air.
In winter, with the sun lower in the sky and shorter daylight hours, coupled with rush hour traffic, frosty and/or foggy windscreens can all combine to create a dangerous driving cocktail.

MANAGING A FOGGY WINDSCREEN
Of course prevention is all very good and well, but what’s the best approach if you do have a foggy windscreen?
Try to avoid using your hand or sleeve. While this may give an immediate improvement the windscreen will soon re-fog as the moisture level and windscreen temperature haven’t changed. There also has the potential to mark the windscreen with oils, smears, and dirt causing reduced visibility.
I hope these tips help you avoid interior windscreen fogging and enjoy a safer and more comfortable driving experience.
