The human sense of smell is a very sensitive thing, so much so that a clean-smelling home can play a large part in your emotional and physical health. Make your own earth-friendly freshener spray by mixing equal parts lemon juice and water and storing it in a spray bottle you’ve salvaged from some of your old cleaning products (make sure to rinse it out well first). Spray this around your home once or twice a week for odor control, or as needed when cooking or to get rid of smells that have seeped into the draperies, couch, and other fabrics.
