Here's a thought....where does baking soda come from? As I was watching Oprah with Dr. Oz, he stated that baking soda is the best cleaning agent. The reason being that it is all natural; there are no chemicals, which in turn is great for the environment. I thought I'd give it a try, the box only cost me $0.87.
To my surprise it works great! But as I was cleaning with this little gem, I thought to myself, "Where does baking soda come from?" I really don't have any idea, but just wondering if anyone knew.
