Baking soda's well-known ability to absorb odors in the refrigerator works just as well in the bathroom. If the sight of an open box seems unaesthetic, mix the soda into your favorite scented bath salts. Set the mixture in a pretty dish on the back of the toilet tank. Its freshening power should last for about 3 months.
To combat odors that emanate around the sink and drain, add 1/2 cup (120 milliliters) baking soda to the toe of an old pantyhose leg or nylon knee high. Tie it off and knot the leg around the pipes under the sink as a hanging sachet. If you don't happen to have any old pantyhose lying around, you can make a pouch from a large square of cheesecloth or cotton fabric. Place the baking soda in the middle, then gather the excess material up around it and secure the ball of baking soda with a rubber band. Tie on a length of string or twine and hang it under the sink.
When you change the baking soda deodorizing your refrigerator, pour the used box down the bathroom drain. You can also sprinkle baking soda in the bathroom trash can after each emptying [source: Dwight & Church].
