Once the spots are gone, you’re left with one problem: the smell. Your car now smells like a deli counter. To banish the vinegar odor, sprinkle a generous amount of baking soda over the damp area. Baking soda is the janitor of odors—it sweeps them away.
Let it sit for at least 15 minutes. While you wait, consider starting a car-air-freshener collection. Vacuum up the baking soda with a brush attachment, and your seat will smell like nothing at all—which is the ideal car smell, really.
