Methods: Use white vinegar or apple cider vinegar or other acidic substances
Soak the stained place with grape juice in white vinegar or apple cider vinegar, wait for a while, and then wash it off with water after repeated rubbing.
Note
1, please do not use soap to wash, because soap is alkaline, not only can not fade, but will make the color of grape juice stains aggravated.
2, for fresh fruit juice or grape juice just splashed on the clothes, you should change it immediately, sprinkle it with table salt, then wash it with water, and then wash it with washing powder.
