One of the best natural ways to deodorize your laundry room is with a citrus spray. Orange, lemon, lime, and grapefruit peels are packed with odor-fighting agents. Place peels in a pot of boiling water. Reduce heat and simmer for one hour, adding water as needed. Strain liquid into bowl and once cool, pour into a clean spray bottle. Spritz this around your laundry room for a sunny scent.
