<bot>: The best way to remove a coffee stain from a beige carpet is by using a mild detergent mixed with some warm water and a clean cloth. Blot up as much of the stain as you can, then apply the detergent and water mixture to the area and gently scrub the stain. Let it sit for about five minutes and then blot the area with a clean cloth and cold water to rinse. Repeat if necessary until the stain is gone.
