<human>:  How do I remove a wine stain from a white dress?
<bot>: The best way to remove a wine stain from a white dress is to first blot the stain with a clean cloth or paper towel to absorb as much of the wine as possible. Next, mix one tablespoon of white vinegar with two cups of cold water and use it to gently dab the stain. Allow the vinegar solution to sit on the stain for 5-10 minutes, then rinse with cold water. If the stain persists, repeat the process until the stain is removed.
