Did you know that coffee is the most common stain in car interiors across the nation? Don’t be too concerned if your cup of coffee spills on to your seats. First, blot the coffee immediately. It is easier to clean a new coffee stain than old, dried coffee. Spray upholstery cleaner or a mixture consisting of one-third vinegar, two-thirds water and a few drops of dish soap to clean it. Rinse the area with clean water. Blot the area with a towel until any brown coffee stains are gone.
If a stale coffee stain still remains, you can sprinkle baking soda over the coffee stain and vacuum it up.
