Perhaps you have leftovers that you've forgotten about. Or, jelly has spilled onto the side of the jar or liquids have spilled from containers onto the refrigerator racks. Over time, these things can leave your refrigerator looking awful and smelling bad. Cleaning your refrigerator is simple and leaves your fridge smelling fresh and looking new.
Unplug the refrigerator power cord. Although you are not working directly with any electrical wires, it is a good safe practice to disconnect the power. Fill the kitchen sink with warm soapy water, just as if you were preparing to wash dishes.
Open the refrigerator door and remove the contents from the unit. This is a good time to throw out any old food and containers that have been forgotten. If your refrigerator smells bad, identify the foods causing the odor and throw them away. Most often the foul smell is coming from expired dairy products or spoiled produce. Repeat the process for the freezer.
Pull out the shelves and drawers. Wash them in the sink of soapy water, and rinse with warm water. Place drawers upside down over dish towels and set racks on end in a dish drainer to dry while you continue cleaning the refrigerator.
Fill a cleaning bucket with 2 tbsp. of baking soda and 1 gallon of warm water. Dip a rag in the baking soda water and wipe down the walls of the refrigerator. Wipe the inside door panels and the bottom of the refrigerator. If necessary soak the bottom of the refrigerator with some baking soda water to soften stains and stuck foods. Wipe clean with a dry towel. Clean the freezer in the same manner.
Wash the outside of the refrigerator and the door gaskets with a rag dipped in the dish water. Wipe the gaskets and outside of the refrigerator dry with a towel.
Dry the shelves and drawers with a towel if they are still wet. Insert them back into the refrigerator. Place the contents back into the refrigerator, wiping down any jars and containers that might have spills on them. Plug the power cord back into the wall outlet.
