You can skip the pricey carpet fresheners and deodorizers because you can cheaply make your own! In a clean container place 1 cup of cornstarch and 1 teaspoon of ground cloves. Shake to combine. Then sprinkle on your carpet or rug (always test in an inconspicuous spot first). Let this sit for 20 minutes and then vacuum up thoroughly. The cornstarch is absorbent so it will soak up odors while the cloves leave a pleasant, homey scent behind.
