Lemons can be used all over your home to help deodorize it. If the smell of your garbage disposal is getting a little overwhelming put lemon peels down it to get rid of the smell. If you want your whole kitchen to have a lemon scent and not just the sink, cut a lemon in half and place it (cut side up) in a bowl of water and let them sit.
Lemons are also a great aid for your fire. Throw some lemon peels directly into the flames to give your fire a fresh smell. Or, if you have a wood-burning stove, place an enameled cast-iron pot or bowl on top, fill with water, and add lemon, and/or orange peels, cinnamon sticks, cloves, and apple skins. No wood-burning stove? Use your stovetop instead and just simmer the water periodically. These aren't the only uses for lemons, try these other ways too.
Oranges can be used in all of the same ways that lemons are used to deodorize your home. They can also be with cloves to make pomanders. Pomanders have been used for centuries to fill small spaces with a delightful fragrance as well as to combat moths. They are also incredibly easy to make: Take a bunch of cloves and stick them into an orange, covering the whole surface. That’s it. Pretty simple, huh? Now suspend your pomander using a piece of string, twine, or monofilament fishing line inside a closet or cupboard, and it will keep the space smelling fresh for years. Here are other uses for orange peels
Is an unpleasant odor wafting from your garbage disposal? Freshen it up with salt. Just dump in 1/2 cup salt, run the cold water, and start the disposal. The salt will dislodge stuck waste and neutralize odors.
What could be more welcoming than the smell of something good cooking? Instead of using commercial air fresheners, simply toss a handful of whole cloves or a cinnamon stick in a pot of water and keep it simmering on the stove for half an hour. Or place a teaspoon or two of the ground spices on a cookie sheet and place it in a 200°F (93°C) oven with the door ajar for 30 minutes. Either way, your house will naturally smell spicy good.
