Grape juice stains should always be treated before a garment is washed. Age and high heat can permanently set the stain. As soon as possible, flush the stain with cold water even if you can't treat the stain. After flushing with cold water, rub in your favorite laundry detergent completely covering the stained area. Now rinse under hot water using the full force of the water's flow to push the stain out of the fabric. If the stain is removed, launder as usual.
If the stain remains, make a solution of warm water and oxygen-based bleach. Allow the garment to soak overnight. If the stain is still visible, rinse and repeat this step. If the stain is gone, launder as usual.
If the garment is dry clean only, point out and identify the stain to your professional cleaner. If you are using a home dry cleaning kit, be sure to treat the stain with the provided stain remover before putting the garment in the dryer bag.
