If your home is smelling a little pungent thanks to good old-fashioned Summer sweat or maybe the fish and chips you fried up for dinner, you can make a natural air freshener to kick those odors to the curb. During your endless Summer, citrus is the key to keeping things smelling sweet. Peel off the rinds of lemons, oranges, grapefruits, or what have you and simmer them in a large pot. Toss in some cloves and star anise and let it be. Soon, the interior of your home will smell as fresh as your backyard lemon tree!
