This article will guide you on safely and effectively storing baking soda. This basic ingredient is usually packaged in a plastic bag and should be stored in a cool, dry place away from acidic moisture.

How to Store Baking Soda Safely and Effectively

How to Store Baking Soda Safely?

The key to properly storing baking soda is to keep it out of heat and moisture, which can cause a chemical reaction that will reduce its effectiveness. Your best option is an airtight container stored in a cool environment. Here are various options for storing baking soda.

Vacuum-Sealing Baking Soda

Baking soda can be stored in many different ways, and vacuum sealing it is an easy way to preserve its freshness for years. Baking soda can last for about one to three years when stored in its original packaging, and it can last for as long as 25 years when sealed in a plastic bucket.

Baking soda should be stored in airtight containers, not in cans because it can absorb odors from the cans. Also, baking soda releases moisture and may interact with metal. If you vacuum seal it, you can avoid many problems, including oxidation. Baking soda will not spoil, but it will clump and must be crushed back into powder before it’s used.

Baking soda is a valuable resource that can last for years. If you store it properly, you can save money while minimizing the chance of mold. If you want to preserve baking soda for years, you should use a storage container that can handle the weight.

Keeping Baking Soda in an Airtight Container

Keeping baking soda in an airtight, resealable plastic container is a great way to maintain its freshness. The tight-fitting lid will keep moisture and air out, and you can label it to identify what it contains. These containers are lightweight and easy to carry. They also lock tightly to prevent spills.

Since baking soda absorbs moisture and odors in the air, it is important to store it in an airtight container. This way, you can use it for cleaning and deodorizing purposes longer. However, replacing it every month or so is advisable if you use it in baking.

If you don’t have an airtight container for storing baking soda, you can buy one for a very affordable price. If you’re short on space, you can use an empty coffee can or a mason jar. Ensure that the lid seals tightly, or the baking soda will lose its potency. Another option is storing your baking soda in the refrigerator to prolong its shelf life.

Mason Jars

Mason jars offer an excellent seal. Just be careful not to get any dust on the jar lid because baking soda will quickly absorb any odor of dust. The jar will prevent moisture from reaching the baking soda as long as you remember to screw the lid down firmly.

Buckets with Gamma Lids

You can put baking soda in food-grade buckets if you want to store it in large quantities. However, regular bucket lids don’t offer a good seal. Rather, spend your money on some gamma-seal lids. They are much simpler to open and keep air out.

Mylar Bags

Mylar bags, which include baking soda, are undoubtedly the finest storage option for dry goods. The material keeps all air and moisture out when it is sealed. Mylar bags are discussed here.

Do I Need to Use Oxygen Absorbers When Storing Baking Soda?

No, baking soda does not require the use of oxygen absorbers. Because baking soda doesn’t go bad due to oxidation, it is unnecessary. Additionally, since the iron in the oxygen absorber packets could react with the baking soda, it is preferable to store it without them. Here is more information on oxygen absorbers for long-term food storage.

Is it Safe to Use Baking Soda if it has Expired?

We frequently make long-term mistakes when storing baking soda when unsure how to do it. Perhaps you’ve had baking powder in your home for a while and are unsure of its quality.

Consuming it will not cause damage to health; however, when using it in dessert or cooking recipes, you may realize that it has lost its potency. Therefore, even though there is no health risk, it might no longer function as intended in your recipes.

Similar to how canned foods have set expiration dates, baking soda also has a shelf life established by the manufacturer. You can use baking soda well after the expiration date. However, we don’t advise it.

The following are some problems with expired baking soda:

  • Baking soda undergoes a chemical reaction that causes it to lose its potency; as a result, many DIY deodorants and cleaning solutions no longer work with it.
  • Cakes still rise wonderfully, but old baking soda has a harsh flavor that makes them taste terrible.

What Happens if Baking Soda is not Stored Correctly?

After opening the package, baking powder typically lasts for around two years. Although it is an alkaline substance, keep in mind that it reacts quickly with various acids and microorganisms.

Therefore, if you don’t store your baking soda properly, it could react poorly to humidity, extreme heat, or cold or become a host to insects or other microorganisms that could reduce its efficacy. Although it is not harmed any more, this substance no longer works as well.

It is crucial to store it properly to avoid discovering that it did not work as intended, even though it was in good condition when you used it in your recipes. Its effectiveness will have diminished.

How to Tell if Baking Soda is Bad?

A prepper household always has one of those ingredients on hand: baking soda. It has so many applications, including cleaning, cooking, and personal hygiene, that having some on hand is crucial. Have you ever thought about how long baking soda lasts, though? Or what if it turns bad?

Yes, baking soda can become contaminated. But it takes time and some pretty extreme conditions for that to occur. Here are some procedures you can use to determine whether your baking soda is still potent.

1) Verify the expiration date. Baking soda comes in most commercial brands and is packaged with an expiration date. If the date has passed, the baking soda might not be as effective as it once was. This does not, however, imply that it is defective and should be discarded, just that it might not perform as well as freshly prepared baking soda.

2) Check for stains: Baking soda is a white powder, so the product starts to deteriorate if the packaging has any stains.

3) Check for smells: Baking soda should have no smell. Baking soda has gone bad if you notice any strange smells coming from the container. It would be best if you discarded the container immediately.

4) Examine the baking soda for lumps: it should be a fine powder. If the powder has any lumps or clumps, that is a sign of deterioration, and you should throw it away.

5) Test its effectiveness: The best way to tell if baking soda is still good is to use it in an acid-based recipe, such as a cake or cookie recipe. If the baking soda doesnufffdt react with the acids in the recipe and produce bubbles or foam, then stuffs time to toss it and get fresh baking soda from your prepper supplies.

Baking Soda Storage Tips

Sodium bicarbonate, sometimes known as baking soda, is a cheap, easily accessible chemical used for various household tasks. Here are some suggestions on how to store baking soda to keep it effective and fresh.

It’s best to keep baking soda in a dry, cool environment. It’s a good idea to store it in the refrigerator if you live in a humid area to stop it from gathering moisture from the air.

Check the expiration date on the packaging before using baking soda for cleaning. The ability of expired baking soda to remove stains and odors may be diminished.

Combine baking soda and water to make a paste before using it to clean. You can add vinegar or lemon juice to the cleaning solution for more difficult stains and odors.

Do I Need to Use a Desiccant to Store Baking Soda?

Desiccants are used in food packing to control moisture. Some people decide to lay a desiccant on the baking soda before sealing the container to prevent clumping.

However, you are not required to do this; you can grind the baking soda into a powder if it clumps.

Checking the Baking Soda’s Quality

To find out if baking soda that has expired can still be used, perform the following test:

  • Add a teaspoon of lemon or vinegar to the cup.
  • Add some baking soda in small amounts.
  • If the baking soda fizzes right away, it’s still good. The efficiency of the baking soda is reduced if the bubbles are little or slow.


To extend the life of baking soda and keep it from absorbing unnecessary scents, it is essential to treat it like a diamond.

The best way to do this is to store it in a sealed container or use the other methods mentioned above in a ply, cool, and odor-free.
