The best way to remove a coffee stain from carpet is to blot the stain with a clean, absorbent cloth. Use a mixture of one part water and one part mild soap to make a cleaning solution. Apply the solution to the stain and lightly scrub with a damp cloth. Blot the area with a clean, dry cloth until the stain is removed. For a deep stain, repeat the process until the stain is gone.
