We've all seen those little jars of essential oils in the supermarket and wondered what to do with them. Try this easy and effective DIY idea to create a deodorizing and natural alternative to air fresheners: Upcycle a clean plastic container with a lid by filling it with baking soda. Add 15 to 20 drops of your favorite essential oil scent, and shake the container with the lid on. Use a hole punch to perforate the plastic lid. Place the lid back on and let the natural fragrance fill the air wherever you need a pleasant scent. The baking soda will absorb odors, and the essential oils will release fragrance.
