Not only does baking soda cause batter to rise when baked, it can also be used as an effective cleaning agent and odor eliminator. When implemented in certain ways, baking soda will make your teeth cleaner, your hair shinier and may be used as a home remedy for indigestion. Because of its many benefits, you may want to keep baking soda on hand, and if stored properly, it will have a very long shelf life.
Dry your hands thoroughly so as not to moisten the baking soda.
Pour baking soda into a container with a lid and place the lid on the container. Covering the baking soda will improve its longevity, but you can keep it in the box opened or unopened if you prefer.
Store in a cool dry place such as a cupboard or pantry. Keep the baking soda out of the fridge if it will be used for baking, since the moisture will cause it to deteriorate and become lumpy.
Test to make sure your baking soda is still usable by mixing 1 teaspoon with 3 tablespoons of vinegar. If the mixture becomes bubbly, you're good to go. Keep your baking soda covered in a cool dry place, and it may have a shelf life of up to two years.
