A garbage disposal is a hardworking kitchen appliance, but without regular cleaning it can develop unpleasant odors and buildup. Fortunately, keeping it fresh and clean doesn’t require harsh chemicals or professional help. With a few simple household items and safe techniques, you can maintain your disposal and extend its lifespan.

Baking soda and vinegar method;

One of the easiest and most effective ways to clean a garbage disposal is with baking soda and vinegar. Start by pouring about half a cup of baking soda into the disposal. Follow with one cup of white vinegar. The mixture will fizz, helping loosen grease and food residue. Let it sit for 10–15 minutes, then flush the disposal with hot water while running it to wash away debris and neutralise odors.

Ice and salt for buildup;

Ice is excellent for dislodging stuck-on grime and sharpening the disposal blades. Drop two cups of ice cubes into the disposal, then add about half a cup of coarse salt or rock salt. Turn on the cold water and run the disposal until the ice is crushed. This method scrubs the interior walls and helps remove grease buildup safely.

Citrus for freshness;

Citrus peels not only clean but also leave your disposal smelling fresh. Cut lemon, lime, or orange peels into small pieces and feed them into the disposal with cold water running. The natural oils help break down grease while the citrus scent eliminates lingering odors. Avoid overloading the disposal—work in small batches.

Dish soap and hot water;

For routine maintenance, a simple dish soap flush works well. Squirt a few drops of grease-cutting dish soap into the disposal, then run hot water for a minute while the disposal is on. This helps remove light grease and prevents buildup from forming over time.

*Cleaning the splash guard

The rubber splash guard (or baffle) is often overlooked but can harbor bacteria and smells. Turn off the disposal and gently lift the rubber flaps. Scrub underneath with an old toothbrush and warm, soapy water, or spray with vinegar and wipe clean.

What to avoid

Never put your hand inside the disposal, even if it’s turned off. Avoid harsh chemicals like bleach or drain cleaners, which can damage the unit and pipes. Also, don’t grind fibrous foods, grease, or large bones, as they contribute to clogs and odors.
