<human>:  How do I easily remove red wine stains from a white shirt?
<bot>: To easily remove red wine stains from a white shirt, soak the stained area in cold water as soon as possible. Then, mix together equal parts of white vinegar and water and dab it onto the stain. Leave it for around 15 minutes before laundering normally with detergent. Make sure you check the stain before putting the shirt in the dryer.
