Though you may be very careful about what and how to keep things in your refrigerator, odor might build up inside it at times. This odor can affect other foods stored in the refrigerator and make them inedible. So, cleaning a smelly refrigerator is very important.
Turn off the temperature control of the refrigerator and remove everything from it. You must remove the shelves, wire racks and drawers as well. All spoiled and expired food items must be thrown out. Use a mixture of warm water and dish soap to clean the shelves, wire racks and drawers with a sponge. After rinsing, let them dry. Clean the insides of the refrigerator with a solution made with a quart of warm water and 2 tablespoons baking soda. If there is a drip pan, you will have to remove it and clean it with soapy water. Clean all the sticky food jars properly before putting the back inside the refrigerator.
