You don't need to buy expensive air freshener. Use a few ingredients you probably already have at home.
To make a batch:
Essential oil (30 drops)
Water - 3 cups (use distilled water if you intend to spray it on furniture or carpets and make sure you test a small area first)
Baking soda - 1 1/2 tablespoons
Make sure ingredients are blended/stirred well and put in a spray bottle.
