Baking Soda Deodorizer

First, empty the refrigerator and discard any spoiled food. Clean all interior surfaces (shelves, drawers, walls) thoroughly with a solution of warm water and baking soda (about 1-2 tablespoons per quart of water) or mild dish soap. Rinse with clean water and dry. Place an open box or bowl of fresh baking soda inside the fridge to absorb lingering odors. Replace the baking soda every few months.
