I never thought about what I kept in my car—until an icy morning left my tires spinning. A police officer suggested keeping a jar of salt, and it changed everything.
Salt under tires melts thin ice and adds grip, helping you get unstuck fast. It can also prevent windshield ice when sprayed the night before, absorb moisture and odors inside the car, soak up spills, and even help with frozen locks. Mixing it with sand adds extra traction.
It’s not a replacement for winter gear, but salt is cheap, simple, and surprisingly useful. A small jar can turn winter hassles into minor problems—and save you time and stress.
