Fill a spray bottle with 1 to 2 cups of warm water. Use water that is warm to the touch, but not hot.
Add 1/8 cup of baking soda to the water. Close the spray bottle and shake vigorously to help the baking soda dissolve in the water.
Open the bottle and add five to 10 drops of your favorite essential oil, such as lavender, eucalyptus or tea tree. Citrus smells also work to remove unwanted odors from the air. If you prefer, add five to 10 drops of lemon juice to the mixture, in addition to or in lieu of essential oils.
Close the spray bottle and shake vigorously again for 10 seconds. Spray your homemade natural air freshener into the air as you would with an aerosol spray. Use this spray lightly to freshen the scent of fabrics and upholstery. Shake the mixture before each use.
Fill a Mason jar with a lid or an open bowl ¼ of the way with baking soda.
Add five to 10 drops of lemon juice or your favorite essential oils if you want a scented air freshener.
Poke five to seven holes in the lid, depending on the size of the jar, using a nail and hammer. Cover the jar with the lid to prevent spillage. Leave open bowls uncovered, but put them in a place where they won’t be tipped over.
Place your diffusing air freshener into places where odors lurk, such as under sinks, in closets and behind garbage cans in the home.
Shake or stir the mixture gently every few days to mix up the baking soda and enhance the deodorizing quality of your air freshener.
