How to Clean a Garbage Disposal

Introduction

A garbage disposal can easily accumulate grease, food particles, and unpleasant odors. Over time, this buildup can affect performance and lead to slow drainage. Luckily, cleaning a garbage disposal is quick and simple when you use the right methods. This guide explains exactly how to clean your garbage disposal so it stays fresh, efficient, and odor-free.

What You'll Need

• Baking soda

• White vinegar

• Dish soap

• Ice cubes

• Coarse salt

• Soft brush or old toothbrush

• Optional: citrus peels for freshening

Steps

Turn off the garbage disposal and unplug it if possible. Never clean a disposal while it is powered.
Remove any visible food debris using tongs or pliers. Avoid reaching inside with your hands.
Lift the rubber splash guard and scrub the underside with dish soap and a soft brush to remove trapped residue.
Pour ½ cup of baking soda into the disposal, followed by 1 cup of white vinegar. Let the mixture fizz for 5–10 minutes.
Rinse by running hot water for about one minute to flush out loosened grime.
Add 2 cups of ice cubes and 1 cup of coarse salt to the disposal. Run cold water and turn the unit on for 20–30 seconds to scrub the chamber clean.
Finish by grinding a few citrus peels with cold water to eliminate remaining odors and leave a fresh scent.

Alternative Methods

• Drop a dishwasher tablet into the disposal, run hot water, and turn it on to break down grease.

• Fill the sink with hot water and an oxygen-based cleaner, then drain it through the disposal to deep-clean the chamber.

• Use dish soap alone by squirting a generous amount into the disposal, running cold water, and turning it on for 30 seconds.

What NOT to Do

• Do not use bleach, as it can harden grease and damage components.

• Avoid grinding fibrous foods like celery, corn husks, and onion skins.

• Do not pour boiling water into a running disposal.

• Avoid putting coffee grounds into the disposal, as they can compact and cause clogs.

• Never reach into the disposal with your hands.
