Things You'll Need
Cloth or paper towels
The smell of old coffee is pungent and to many people, unpleasant. Coffee odors linger in mugs and cups. If your travel mug spills in the car, coffee on the upholstery, dashboard and other areas creates a more difficult odor problem. Baking soda absorbs coffee odors naturally while serving as a scrubbing agent to help remove stains. Since baking soda will not leave a stain of its own, it's safe to use on virtually all fabrics and leather.
Pour 1 tsp. of baking soda in containers such as coffee mugs and decanters before filling with water. Let sit overnight, then rinse out to remove odors.
Sprinkle baking soda on carpets, upholstery and clothing and leave it to sit overnight. The baking soda absorbs odors and can then be vacuumed away or laundered, if applied to clothing.
Mix three parts baking soda with one part water in a cup and swirl with an old toothbrush into a paste consistency.
Scrub spilled coffee or dried coffee stains with the paste and toothbrush to remove odors and visible traces of coffee.
Blot with a wet cloth or paper towels, let dry and vacuum.
