Everyone wants a perfectly clean carpet; however spills and stains will happen in every environment. Spilled coffee should be cleaned immediately from carpet for best results in removing or preventing a stain. If the stain has set into the carpet, extra scrubbing is required to pull out as much of the stain as possible. Always test a hidden small area of carpet with the detergent or cleaners being used to make sure they will not change the color or texture of the carpet fibers.
Spray the stained area with water and blot the stain with a clean, absorbent towel. Repeat this step several times to remove as much stain as possible.
Apply a mild detergent that has been diluted with water to the stained carpet area. A gentle dish soap or laundry detergent is a good choice. Gently rub the detergent into the fibers with your fingers. Do not push the detergent into the carpet as this will push the stain deeper.
Spray the area with water and blot with a clean towel to remove the detergent and remaining stain. Repeat this process several times until all detergent is gone.
Apply a baking soda paste to the area if the stain remains. Mix baking soda with water until it turns into a paste the consistency of toothpaste. Spread the baking soda paste onto the stain with your fingers. Let the paste dry completely and vacuum to remove.
Create a foaming baking soda paste if the stain remains after applying a baking soda and water paste. Mix vinegar with baking soda to create a paste the consistency of toothpaste. Apply in the same way as Step 4 and vacuum to remove when dried. The vinegar reacts with the baking soda to create bubbling foam that works through the carpet fibers to pull out the stain.
