<bot>: The best way to clean a red wine stain from a carpet is to first blot the area with a paper towel or cloth to remove as much of the wine as possible, then use a mix of 1 teaspoon of white vinegar and 1 teaspoon of dishwashing liquid mixed with 2 cups of warm water, and work the solution into the stain with a clean cloth. Finally, rinse the area with a cup of warm water and dab dry with a clean cloth until the area is completely dry.
