How to store baking soda after opening

1. Store baking soda in an airtight container


Using an airtight container is the best way to store the baking soda after opening.

The airtight container makes sure that there is no air in and out through the coverage gap.

It protects the baking soda from external threats and keeps it fresh.

The content of baking soda will be maintained so that it can be used for a long period of time.

You can use a plastic container, glass jar, or any material to store the baking soda. Just make sure it is the airtight one.

My tip for choosing a baking soda storage place is to make sure the place has a tight lid and is quite difficult to open. This is to ensure that the container properly protects its contents.

It’s great for transferring all the baking soda from an open box to a closed container so it doesn’t get exposed to moisture.

2. Store it in a resealable plastic zip bag

Plastic zip is another way to store baking soda after opening.

It is a type of plastic container for storing and packaging.

It has a resealable lid to keep the contents from spilling and from being affected by the outside condition.

The zip-lock system will keep the baking soda fresh and protect it from humidity or moisture.

It is also easy to transport from one place to another. You can also bring it in your bag in case you might need it.

You can also open it and lock it easily after using it.

3. Store it in a resealable plastic


Resealable plastic is a fine container to store baking soda after opening.

This plastic has a tight lid which can be opened and closed as needed.

This sealing method will ensure that your baking soda stays good and fresh. Resealable plastic containers are also easy and light to carry around, so you can bring them anywhere with you.

You don’t have to worry about the container breaking or spilling its contents because it has a tight lid that will keep everything inside safe and secure.

What should you do after storing baking soda?

1. Put a label on the container


After putting the baking soda into the container, give it a label.

Many people mistake baking soda for other materials such as baking powder or flour.

A simple label will help you keep track of what’s in the container.

You can use any type of marker or pen to create your label.

Make sure that the writing is large and easy to read so that you won’t have any problems later on when trying to identify what’s inside the container.

You can also do this by attaching a special label to the surface.

2. Write the expiration date

Any materials have their own expiration date, including baking soda.

Take a look at your baking soda box and you will see the expiration date.

After storing it in a container, make sure to put the expiration date.

It is important to avoid using expired baking soda.

3. Keep it in a cool and dry place

To keep your baking soda fine, store it in a cool and dry place.

Avoid putting it in a wet area such as near the sink.

Store baking soda away from direct sunlight and heat sources like ovens or fireplaces.

It can lose its effectiveness over time if exposed to heat or humidity.

What you should not do to store baking soda after opening

1. Don’t use a container without an airtight seal

Always use a sturdy and strong container to store baking soda. Make sure there is no crack or gap for air to enter.

Avoid using thin containers as they are usually not airtight.

2. Don’t store it in a container that has been used to store other chemicals, such as cleaners.

To keep your baking soda fresh after opening, don’t store it in a container that has been used to store other chemicals, such as cleaners.

There is a high chance that the used bottle contains chemical residues that can damage the content of baking soda. In fact, the alkaline nature of baking soda can be damaged by reacting with other chemical compounds.


You know you should be using baking soda in your daily life, but do you know what to do with baking soda once its packaging is opened?
