Does Baking Soda Actually Remove Smells in the Fridge?

Baking soda absorbs and neutralizes odors in the fridge and freezer, rather than simply masking them. Baking soda is a weak base that is amphoteric, meaning it can react with acidic (like spoiled milk) and sour-smelling alkaline (like fish) molecules and turn them into neutral-smelling sodium salts. Baking soda also absorbs moisture, which can help fresh food last longer as well as dull bad smells.
How Do I Freshen My Fridge with Baking Soda?
The easiest way to help freshen your fridge is with a box of ARM & HAMMER™ Fridge-n-Freezer™ Odor Absorber! The spill-proof package has dual panel flow-through vents for max odor control. Simply remove the front and back cardboard panels and place one upright box in your fridge and freezer, or in the crisper drawers so your fruits and veggies stay fresher, longer!
Alternatively, you can use the Fridge Fresh™ Refrigerator Air Filter, with suction cups that stick to the interior sides of most refrigerators.
How Long Does it Take for Baking Soda to Remove Odors?
Adding one box of Fridge-n-Freezer™ or regular baking soda should help remove odors from the fridge within as few as two days, depending on the severity of the odors you’ve left behind. However, pairing a deep clean with baking soda in the fridge can help to neutralize odors fast.
For best results, change your box of baking soda in the refrigerator every 30 days and clean your fridge regularly.
Is Baking Soda in the Fridge the Same as Baking Soda for Cooking?
Using baking soda in the fridge is NOT the same as using baking soda when you cook. The point of putting baking soda in the fridge is to use it as a deodorizer by absorbing and neutralizing odors. Surely you wouldn’t want your food to taste like the bad smells the baking soda absorbed! Use fresh baking soda when cooking or baking.
How Often Should You Use Baking Soda in the Fridge?
One box of baking soda freshens your fridge or freezer for around 30 days. Any odor neutralizer gets less effective over time as it absorbs odors and moisture. If your fridge has started smelling funky again, it might be time for a change. You can write the date on the box so you’ll remember to change it out and keep the odor neutralizing powers going strong.
Why Does My Fridge Smell Bad?

Refrigerator odors are often the result of bacteria or mold, typically because of spoiled food or moisture buildup. Additionally, plastic absorbs odors, so many of your storage containers might contribute to smell if kept in the fridge too long. Finally, there’s a chance you might need a new water filter.
Getting rid of odors in your fridge can require a combination of things, including cleaning out spoiled foods, wiping down surfaces, and replacing filters. You’ll also want to clean smelly plastic food containers by scrubbing them in a mixture of hot water and baking soda. Keep a box of baking soda in your refrigerator and freezer to help absorb and neutralize odors and replace it every 30 days to help keep your fridge fresh.
So, Is Baking Soda Good For Your Refrigerator?
Baking soda is an excellent tool not only for refreshing your refrigerator and freezer, but also for things like cleaning fridge shelves, oven surfaces and grill grates. It’s the solution that can help give the whole home a boost while absorbing odors in the fridge and freezer to help keep food tasting fresher, longer.
