First, clean out your fridge. Throw away any expired food and wiping down all surfaces with a mild detergent (dish washing liquid will do) and warm water. Don’t forget to remove and soak your refrigerator veggie drawers and meat pans, since nasty bacteria can grow there.
After washing all the surfaces in your fridge, be sure to dry them thoroughly. Fill an open container – like a bowl – with dry baking soda and leave it on the bottom shelf. The baking soda will absorb any future odors from lingering near your food, so do not remove it when you refill your fridge.
Many modern refrigerators come with inside filters that also control odors. Don’t forget to change these on a regular basis to block and control odors inside your fridge. The Whirlpool Fresh Flow Refrigerator Filter is 15 times more powerful than baking soda in neutralizing odors and bacteria inside the fridge.
