How to Reduce Car Window Condensation

Winter mornings often come with an annoying surprise, fogged-up car windows. Do you leave your car outside over night during the winter months and condensation builds up by the morning? 

Not only is this frustrating when you’re in a hurry, but it can also be unsafe while driving.

Thanks to a clever tip shared by one of our readers, there is a simple, cost-effective, and eco-friendly solution to help keep your windshield clear.

The trick? Coarse salt.

By placing around 1 kilogram of coarse salt inside a cotton bag and keeping it in your car, you can dramatically reduce windshield condensation. Salt naturally absorbs moisture from the air, helping to prevent fog from forming inside your car during those damp winter days.

Extra Tip: Protect Your Dashboard

To avoid any risk of dashboard corrosion, it’s best to place the cotton bag on an aluminium plate or a piece of plastic. This creates a barrier in case the bag ever gets damp, protecting your car’s interior.

Why We Love This Idea

Instead of idling your engine or cranking up the heater to clear the fog, this little bag of salt works quietly in the background. It’s:

Practical and inexpensive

Energy-saving and eco-friendly

Super easy to make and use

Sometimes the simplest solutions really are the best. A cotton bag, a bit of coarse salt, and you can say goodbye to foggy windows this winter!
