How Do I Get Rid of the Smell of Sour Milk in a Car?

Spoiled milk in the close confines of a vehicle is an unpleasant smell and resists many cleaning methods. Use vinegar, baking soda and coffee grounds to eliminate the odor and to keep your car smelling fresh. The process is quick but requires some time for the carpet to dry, which you can reduce by directing a fan on the wet spot.
