If your kitchen has a lingering smell you cannot place, the garbage disposal is often the source. Food residue builds up on the blades and walls and starts to smell. Here is how to clean it safely.
Why it smells
Bits of food get trapped in the grinding chamber and under the splash guard, where they decay and cause odor. A quick rinse does not reach them.
Ice and salt scrub
With the disposal running and cold water flowing, drop in a cup of ice cubes and a handful of coarse salt. The ice scours the chamber and blades without you ever putting your hand inside.
Baking soda and vinegar
Turn the disposal off. Pour in baking soda, followed by white vinegar, and let it fizz for several minutes to break down residue and neutralize odor. Flush with hot water.
Finish with citrus
Run a few lemon or orange peels through the disposal with cold water for a fresh scent. Also lift and wipe the rubber splash guard, a spot that hides a surprising amount of grime.
What never to put down it
Avoid grease, coffee grounds, eggshells, and fibrous foods like celery, which cause clogs and odor over time.
