The Simple Salt Method
Continued on next page:
One inexpensive approach involves placing a cup of ordinary table salt inside the vehicle. Salt naturally attracts and holds moisture, allowing it to absorb some of the dampness present in the surrounding air.
The method does not require electricity, wiring, installation, or a specialized product. It uses a common kitchen ingredient that many households already have available.The salt should be placed in a stable container and positioned where it is unlikely to tip during normal use of the vehicle. A secure cup holder or another flat, protected area can help prevent spills.

Once positioned, the salt remains inside the carand gradually interacts with the humid air. The goal is to reduce the amount of moisture available to settle on the cold glass.
This is not an instant replacement for wiping the windows or using the car’s heater and ventilation system when visibility is already blocked. Instead, it is a passive method intended to address the damp conditions that contribute to repeated fogging.
