Repurpose as: Kitchen Deodorizer
When life gives you lemonade, use the leftover lemons to create a citrus-fresh smell in your kitchen. Rub half of a (previously squeezed) lemon on cutting boards to remove odors—even that of garlic and onion, says Betsy Jabs of DIY Natural. Lemons also work to remove the same smells on hands. Or, drop a few rinds down the garbage disposal to give the sink a fresh scent.
