How Long Does Baking Soda Last? Does it Go Bad?

Have you ever wondered how long your baking soda will last?

Are you the type of person who stocks up on essentials and hates to waste anything in their kitchen?

If so, you might be surprised to learn that baking soda can actually go bad.

While it’s always a good idea to keep extras on hand for cooking and cleaning purposes, if it’s been too long since your last purchase—or if it’s older than two years—you may want to think twice about using it.

To help lessen any confusion or frustration associated with knowing when something needs replacing, let us give you the rundown on how long does baking soda last and other details related to this critical pantry staple.

What’s Baking Soda?

Baking soda is a common household ingredient that can be used for cleaning, cooking, and baking.

It’s also known as sodium bicarbonate or simply bicarbonate of soda.

Baking soda is a white powder that is soluble in water.

When it’s combined with an acid, it releases carbon dioxide gas, which gives baked goods their fluffy texture.

Baking soda has a long history of being used as a leavening agent in baking.

When combined with an acidic ingredient like buttermilk or yogurt, it helps cakes and breads rise.

It’s also often used as a natural cleaning agent because it’s abrasive and can help remove stains.

Despite its many uses, you may be wondering whether baking soda expires.

Here’s what you need to know about the shelf life of baking soda and how to tell if it’s still good to use.

How to Store Baking Soda?

When it comes to storing baking soda, there are a few things you need to keep in mind.

First of all, baking soda should be stored in a cool, dry place.

If it gets too warm, the baking soda will start to break down and lose its effectiveness.

You also want to make sure that the container you’re using is airtight.

Baking soda absorbs moisture from the air, so if it’s not in an airtight container, it will start to clump up and won’t work as well when you use it.

Another thing to keep in mind is that you shouldn’t store baking soda near anything that has a strong odor.

Baking soda is very good at absorbing odors, so if you store it near something with a strong smell (like garlic or onions), the baking soda will absorb that smell and won’t work as well when you use it.

So, to sum up, the best way to store baking soda is in a cool, dry place in an airtight container away from anything with a strong smell.

By following these simple tips, you’ll ensure that your baking soda will be fresh and effective when you need it.

How Long Does Baking Soda Last?

Baking soda is an extremely versatile product that can be used for a variety of purposes, from cleaning to cooking.

But one question that many people have is how long does baking soda last?

The answer to this question is that baking soda generally has a shelf life of about two years.

However, there are a few things that you can do to extend the shelf life of your baking soda.

One way to do this is to store it in an airtight container.

This will help to keep moisture and other contaminants out of the baking soda and prevent it from going bad prematurely.

Another way to extend the shelf life of your baking soda is to keep it in a cool, dry place.

Baking soda is sensitive to temperature and humidity, so storing it in a pantry or cupboard away from any heat sources is ideal.

If you follow these simple tips, you can be sure that your baking soda will last for two years or longer.

And if you ever have any doubts about whether or not your baking soda is still good, simply give it a sniff – if it smells off, it’s time to toss it and get a new one.

Can You Freeze Baking Soda?

Yes, you can freeze baking soda.

In fact, freezing baking soda is a great way to extend its shelf life.

Baking soda will last indefinitely if it is kept frozen.

There are a few things to keep in mind when freezing baking soda.

First, be sure to store the baking soda in an airtight container.

This will prevent it from absorbing any moisture or odors from the freezer.

Second, when you are ready to use the baking soda, be sure to thaw it completely before opening the container.

This will help prevent any clumping that may occur.

Frozen baking soda can be used in all the same ways as fresh baking soda.

It can be used for baking, cleaning, and even as a deodorizer.

The only difference is that you may need to use more baking soda than usual when using it frozen, since it will be less potent than fresh baking soda.

How to Tell If Baking Soda Is Bad?

Baking soda is a powerful leavening agent that helps baked goods rise.

However, over time, baking soda can lose its potency and become less effective.

There are a few simple ways to test whether or not your baking soda is still good.

One way to test the potency of baking soda is to mix it with vinegar.

If the mixture fizzes and bubbles, then the baking soda is still good.

If there is no reaction, then the baking soda has lost its power and should be replaced.

Another way to test the freshness of baking soda is to add it to hot water.

If the baking soda dissolves quickly and completely, then it is still fresh.

If it takes a long time to dissolve or does not dissolve at all, then it is time to get a new box of baking soda.

If you’re not sure whether or not your baking soda is still good, it’s always better to err on the side of caution and replace it.

That way, you can be sure that your baked goods will turn out perfectly every time.


Baking soda is a great baking ingredient that has many benefits.

It is a cheaper alternative to other baking ingredients, it is easy to store and it has a long shelf life.

However, baking soda can go bad if it is not stored properly.

To tell if baking soda is bad, look for clumps, an off odor, or a change in color.

If you notice any of these signs, it is best to discard the baking soda and get a new one.
