Instead of using toxic chlorine bleach to whiten whites, head to the produce section of the supermarket. Real lemon juice can have almost the same brightening power of bleach and will help remove rust stains and dullness. Just add about 1/4- to 1/2-cup lemon juice to the wash cycle and let the natural bleaching properties of the lemon juice do its work. An added benefit? Lemon juice smells fresh and clean, and your clothes will, too.
