Your red shirt got mixed in with other clothes and ruined them? First off, DON'T DRY THEM! Wash again with regular detergent and color-safe bleach. If that didn't work, Rit®, the makers of clothes dye, makes a color remover that works wonders and doesn't cost much. To prevent bleeding in the first place, wash in cold water; I also use a cup of salt OR a scoop of Oxi Clean® with every load.
