Put a Glass of Salt in Your Car: Here’s Why Some Drivers Try This Simple Trick
If your car windows are constantly fogging, investigate the vehicle instead of assuming that weather alone is responsible.
Chemistry
Start with the floor.
Press your hand firmly against the carpet in the front and rear footwells. Check underneath removable mats. The surface can sometimes feel dry while padding underneath remains wet.
If you discover persistent dampness, determine where the water is entering.
Check Door and Window Seals
Rubber seals around doors and windows are designed to help keep rain outside the cabin. Over time, they can become damaged, dirty, compressed, loose, or cracked.
Herbs & Spices
After heavy rain, inspect the edges of the doors, seats, carpets, and trim for moisture.
A recurring wet area near the same door can provide an important clue.
Check the Trunk
Drivers often inspect the passenger compartment and forget about the trunk.
Water can sometimes enter around trunk seals, rear lights, body seams, or other openings. Depending on the vehicle, it may collect beneath the trunk carpet or around the spare-wheel area without being immediately obvious.
Autos & Vehicles
A damp trunk can contribute to humidity throughout the vehicle.
