What is the difference between baking soda and washing soda?

•Baking soda primarily is used in cooking as a leavening agent that causes cakes and cookies to rise. It also is used as a deodorizer by placing an open box in the refrigerator, sprinkling it on your carpet and then vacuuming it up or by sprinkling some in shoes. It can be safely handled by anyone.

•Washing soda most often is added as a booster to laundry detergent. It also can be mixed into a paste and used to cut grease, clean oil and remove wax or lipstick, and to scour a stained sink. Test washing soda paste on an inconspicuous spot before using because it could harm some finishes.
