What are the common uses of baking soda?

Very good question. I'm glad you asked. Besides baking cakes & cookies you can use it for lots of other things. Use it to brush your teeth - just sprinkle some into your hand & use a wet tooth brush to pick it up. Mix a spoonful in a half glass of water and drink it if you have an upset tummy. Put a cupfull in with your laundry to get it cleaner. Mix some with water to make a paste & put it on a bee sting. Put some in your bathtub to sooth your skin if you have a sunburn or a rash. Use it as baby powder. Sprinkle it in your shoes to eliminate odor. Put an open box of soda in the refrigerator or freezer to get rid of odor. Wet your sink and use the soda to scrub it clean. There are lots more uses for it, but I have to go offline now. I hope these ideas are what you wanted to know.
