Freshen Up the Stinky Garbage Disposal

“Lemon rinds ground in the disposal will deodorize your sink’s drain 1-2-3,” says Edelman. “And bonus, unlike vinegar, which leaves no scent, lemons provide a clean, crisp aroma.” Just slice a lemon into chubby quarters, slip them into the sink’s disposal, turn on the hot water and flip the power switch. Run the disposal until you hear the “gurgle-gurgle-grind-grind” sound—when that noise stops, it means the lemon is chopped and swallowed up. Turn off the disposal.
