Does your fridge still smell like last week's Thanksgiving dinner? Deodorize it: Line the shelves with newspaper and let it sit overnight. It'll absorb odors. You see, newspaper is designed to absorb ink, so it'll absorb other things, too ... like smelly odors! Keep your fridge smelling fresh by placing a bowl of charcoal in the back of the fridge. The charcoal will absorb odors, too.
