Baking soda can be used for a ton of things. I recently got a box from Smiley360 and Arm & Hammer to share tips.
Obviously, it can be used in baking. But I've also used it to help scour out the stove instead of a smelly chemical cleaner. In a pinch it makes decent toothpaste (although the taste is tricky to deal with). It makes a great deodorizer for smelly garbage cans and laundry rooms, and can also help absorb things like oil spills out of carpet. You can also run it through the washing machine with towels to help freshen them when they get musty! Arm & Hammer has many more tips for all areas of your home.
