How to Deodorize Your Fridge and Ways to Maintain It

You’re bound to encounter unpleasant smells in the kitchen, but resist the urge to slam the refrigerator door shut and just forget about it. It will only make the problem worse. 

Water-loving microbes thrive in damp conditions. Because they’re microscopic, they can be found in any refrigerator, but they’re particularly rampant in yours. 

Here are some of the causes of the bad odor in your fridge and a few ways on how you can deodorize it.  

What Causes Unpleasant Smells in the Fridge?

What you’re smelling is usually due to the natural decomposition of the foodstuffs inside your fridge. As the contents of your fridge rot and are exposed to the airborne microbes, including those in the air, the microbes begin to decompose the food.

Because dampness and high temperatures encourage the growth of these microbes, you’ll want to employ a few measures in your fridge to prevent these odors from overwhelming.

Fragrances can also be a culprit when it comes to unpleasant smells in your fridge. Common products that use fragrances such as air fresheners, room deodorizers, and fabric softeners can all cause unwanted smells to develop in your fridge.

What You Can Do to Remove Unpleasant Scents

When it comes to dealing with unpleasant smells, you can do a few things to remove them.

1) Baking Soda

Using baking soda to reduce the smell in your fridge is one of the easiest and most inexpensive ways to remove odors. Simply take a box of baking soda, fill the box with holes or slits to allow air to enter, and place the box inside the fridge.

As the box of baking soda absorbs the odors, replace the box every other month or so as needed, and your fridge will be deodorized and smell fresh.

2) Activated Charcoal

Activated charcoal is another natural odor absorber when dealing with persistent odors in your coolers and refrigerators.

Similar to baking soda, you can use activated charcoal to rid your coolers of unpleasant smells. To do so, simply place the charcoal inside a mesh bag or container, then place it where the odor is present. Because activated charcoal has a porous surface that will suck in the odor, simply place it where the odor is most prevalent or if you can smell it most.

3) Baking Soda and Vinegar

You can use baking soda and vinegar in your fridge to remove odors. This can be done in a few different ways.

In a spray bottle, mix 3 tablespoons of baking soda with 1 cup of white vinegar and a little water. Shake the solution to activate the baking soda and vinegar. Place the solution into a spray bottle, and then use it to spray the entire refrigerator and shelves.

Maintaining a Deodorized Refrigerator

Use a microfiber cloth or paper towel to wipe down the inside of the refrigerator. Use a lemon-scented cleaner or vinegar to wipe down the inside of the refrigerator.

To combat unpleasant smells in the tops of the refrigerator, place a fabric softener sheet or dryer sheet in the refrigerator.


It is always a good idea to inspect your fridge to see if there is a leak or bad odor anytime you are smelling something foul in your kitchen. If you find an issue, don’t hold back and use the tips mentioned above.
