In a large spray bottle, combine two cups of distilled or filtered water with six drops of natural lemon oil (available at health-food stores or online—often labeled as “essential” oil). Make sure your bottle can spray like a mist and not just a steady stream. (You can find fine-mist spray bottles online, but we used a recycled, cleaned-out spray bottle with an adjustable knob.) Shake the spray bottle until the mixture is completely blended. You’re ready to freshen the air!
Now, as a long-term solution, figure out why you have that bad smell so you can fix it for good…
