Kids, even adults, are notorious for spilling juice on their clothing, the carpeting, and more! White vinegar can make even tough grape juice  and fruit punch stains disappear! Rinse the spot with cold water. Now, apply the vinegar to the area. Let this sit for about 10 minutes. Blot with a cloth until the spot is gone. The vinegar odor fades with a damp sponge. The acetic acid in the vinegar chemically reacts with the tannins which is the pigment in most drinks. Wash as usual.
