How it works: Salt absorbs liquid. Spill coffee or a drink on your car seat? Cover it with salt immediately. Let it sit, then vacuum up.
Best practice: Keep a small shaker of salt in your glove compartment for emergencies.
What it won’t do: Remove stains from fabric. Use a proper cleaner afterward.

How it works: Salt absorbs moisture and some odor-causing particles. Placing a container of salt in your car can help reduce musty smells.
Best practice: Combine with baking soda for better odor absorption.
What it won’t do: Eliminate strong odors like cigarette smoke or spilled milk.
