A simple glass of salt in the car might sound unusual, but this old-fashioned trick can be surprisingly useful during winter. The idea came from a police officer who shared the tip after I found myself struggling on an icy road, with my tires spinning and traffic moving slowly around me.

Keeping salt in the car can help in several winter situations. Sprinkling a small amount beneath spinning tires may provide extra grip on icy surfaces, helping the vehicle move again. Salt can also be mixed with water to create a simple solution that helps prevent frost from forming on the windshield, making cold mornings a little easier.

There are other practical uses, too. Salt can help absorb moisture from damp areas inside the vehicle, including carpets, while reducing some unpleasant smells caused by winter humidity.

Of course, salt is not a replacement for winter tires, careful driving, or proper vehicle maintenance. It should also be used carefully because excessive salt can contribute to corrosion on metal surfaces.

Still, keeping a small container of salt in your emergency kit is an inexpensive precaution. When temperatures drop, roads freeze, and car doors become difficult to open, this simple household item may come in handy when you least expect it.
