If the coffee stain is on a shirt or carpet, applying club soda helps lift the stain. Club soda is often available when dining out, and addressing the stain while it is still fresh is a key to effective removal. Beer, vinegar and baking soda are additional options.
Beer is especially effective at removing coffee stains from carpet. Pour beer onto the stain and rub it into the fibers. If stains are difficult to remove, repeating the process is usually successful. If beer is not available, a beaten egg white or baby wipe are possible alternatives.
Applying vinegar before washing a coffee-stained garment helps eliminate the stain. When an item has a large coffee stain, soaking the garment in a mixture of 3 parts distilled vinegar and 1 part water before washing is usually effective at removing the stain. Drying the garment before the stain is removed sets the stain and makes it more difficult to remove.
Baking soda offers a scratch-free option for removing coffee stains from fine china. Apply baking soda with a damp cloth and scrub the stain in small circles. If baking soda is not available, salt makes a good substitute for scouring the stains from dishes.
