Cars are often exposed to strange smells that can stick around—like spilled drinks, damp floor mats, sweaty gym clothes, or even strong-smelling food. Salt is a natural absorbent. It draws in both extra moisture and bad odors, making it a very cheap, non-chemical alternative to expensive commercial air fresheners.
Keeping an open container or glass of salt in a secure spot, like a cup holder, acts as an all-natural deodorizer. Furthermore, if you accidentally spill liquid inside your car, sprinkling a handful of salt on the spot can quickly soak up the liquid before it has a chance to soak deep into the fabric and cause permanent stains.
