Baking soda might just be the best thing hanging out in your kitchen. Besides the fact that it’s a key ingredient in your favorite cookie, baking soda has so many other uses around the house. Use baking soda to unclog drains. A cup of it, followed by a cup of white vinegar and boiling water poured down the drain will clear up many clogs in minutes. It’s great for cleaning pots and pans, and you can use it with an old toothbrush to clean grout.
