If you have area rugs that have absorbed odor from food, pets or cigarette smoke, baking soda offers an easy (and cheap) way to deodorize them. Baking soda particles penetrate deeply into the fibers of the carpet and absorb like mini sponges. Simply sprinkle baking soda liberally on the carpet and let it sit for a few hours or overnight, then vacuum away the next morning. You can use this trick on wall-to-wall carpet, too.
