Spills, mystery stains and everyday messes always seem to show up at the worst possible moment - usually right when you realize you're out of the cleaner you actually need. Before making a store run, take a look in the laundry room. Laundry detergent is designed to break down dirt, oils and grime, which means it can do far more than wash clothes. In a pinch, that bottle beside your washer can help tackle messes all around the house - if you know where to use it.
