How to Store Baking Soda

When it comes to baking soda, is there anything this nifty ingredient can’t do? From being an all-star cleaning solution to masking pesky odors and leavening cookies and cakes, there’s no wonder why baking soda is a staple in everyone’s kitchen. But are you storing it correctly?

I’m Michelle, and, like you, I left my baking soda in its trusted cardboard box for years. But as I grew in my baking journey, I learned the right ways to store baking soda – and now I want to share this information with you!

If you’re wondering how to store baking soda, keep reading and be prepared to say goodbye to the infamous cardboard box!

How to Store Baking Soda in the Pantry

If you’re anything like me (and I am assuming that you are, considering you’ve stumbled across this blog), you routinely used your baking soda and chucked it back into the pantry. But you always left it inside the classic cardboard box.

What if I told you that you were doing it wrong? The problem with storing baking soda in the cardboard box is that there is no airtight seal. This means two things: your baking soda is absorbing all of the odors around it, and it’s losing its longevity.

To maximize the lifespan of your baking soda and make sure it’s ready for anything, consider doing this instead:

  1. Open the new cardboard box of baking soda and use it for its desired purpose.
  2. Store in an airtight container.
  3. When ready to use again, use a spoon or scooper to scoop out the necessary baking soda. 

Yes, it’s that easy to store baking soda in the pantry. An airtight container will ensure that it stays fresh for several years. 

Which Containers Are Best?

Everyone has a different meaning when they hear the word airtight container. For some, this means Tupperware or a glass jar. Others, it’s a plastic bag. While these are both great ideas, the number one option is an empty spice jar or grated Parmesan cheese bottle. 

Why? Because these containers will make it easy for you to pour the baking soda out without needing to open and close a bag or container. You won’t have to use anything to scoop the baking soda out, either, which preserves the baking soda further.

Whichever airtight container you end up choosing, the biggest thing to remember is that the container should be completely void of any odors. The container should also be strategically placed away from spices and other scents in a cool, dry area.

Remember – baking soda absorbs scents. If you put the baking soda in a container with a distinct smell, your baking soda will act fast to absorb it. No, thanks!

How to Store Baking Soda in the Fridge or Freezer

The same rules do not apply to baking soda that is going to be used in the refrigerator or freezer. If you are going to place baking soda in these areas, know that it will absorb unpleasant odors that may emit. 

For that reason, you should never use a box of baking soda for baking if it has been opened and placed in the fridge or freezer. That can lead to a very untasty treat!

To store a box of baking soda in the refrigerator or freezer, simply do the following:

  1. Open the box 
  2. Sprinkle some baking soda in the bottom of the crisper bins
  3. Place the baking soda box inside the fridge/freezer
  4. Replace every three to six months


Below you will find some of the most commonly asked questions about storing baking soda the right way. Let’s dive in!

Can you store baking soda in a glass jar?

Yes! Storing in a glass jar is an excellent option. The same rules apply to this type of container, though. It needs to be airtight and not have any pre-existing odors. 

Can baking soda be stored in a clear container?

Yes, you can store baking soda in a clear container.

Where do you put baking soda in the fridge?

The location of the baking soda is not extremely important. However, if you notice more odors coming from certain areas than others, place the baking soda amid the smelly items.

How long is baking soda good for once opened?

While baking soda boxes have expiration dates on them, they aren’t always exact. The general rule of thumb is that once a box of baking soda is opened, it is only good for six months to a year. Of course, this number changes based on certain factors like how and where it is stored.

Final Thoughts

Treating your baking soda like a gem is important to extend its longevity and keep it from absorbing unnecessary odors. The best way to do this is by storing it in an airtight container in a cool, dry, and scent-free area.
