<human>:  What is the best way to remove a red wine stain from a carpet?
<bot>: The best way to remove a red wine stain from a carpet is to blot the stain with white paper towels or a clean, color-fast cloth as soon as possible. Work from the outer edge of the stain inward to prevent it from spreading further. Then, mix a solution of 1 quart of warm water, 1 tablespoon of dishwashing detergent, 1 tablespoon of white vinegar and 2 tablespoons of rubbing alcohol. Soak a clean, color-fast sponge with the solution and dab the stain with it to remove the remainder of the stain. Once the stain is removed, rinse the area with water and then blot it dry with more paper towels or a cloth.
