How to Clean an Icebox

Remove old food, such as leftovers more than four days old and perishable items past their expiration date. If you have an open box of baking soda more than a month old, it should be replaced at this time. Next, go through the freezer, disposing of items that have freezer burn or are old enough to have lost their flavor. A good rule of thumb: if it's over two months old, toss it.

Unplug your icebox and vacuum the condenser coils in the back and the bottom vent in front. Removing built-up dust makes your refrigerator run more efficiently, and also saves energy. This means your food will last longer, and you'll save money on your electricity bill. While the icebox is pulled away from the wall, wipe down the top and the sides with a damp sponge or cleaning cloth. Also, sweep away any dust underneath. Unplugging the refrigerator gives the freezer a chance to defrost, which means it will be easier to wipe down.

Remove produce and snack drawers and wash them in the sink with warm, soapy water. Some refrigerators have shelves that also can be removed for washing. If you have ice trays, wash those too. Next, mix one part baking soda with four parts water and begin wiping down the inside of the ice box. Pay special attention to the shelves in the door, where condiments can leave a sticky residue, and to the area beneath the produce drawer. Using the same mixture, wipe down the inside of the freezer. While cleaning, remember to include the rubber gasket around the doors.
