How to Clean Your Garbage Disposal Monthly
Cleaning your garbage disposal monthly prevents unpleasant odors, keeps the unit running smoothly, and extends its lifespan. This simple maintenance task takes just 10-15 minutes and requires only common household items that most people already have on hand. Anyone can do this safely without professional help.
What You'll Need
Supplies
- •Ice cubes (from home freezer or ice maker)
- •Fresh lemon or lime fruits (2-3)($1-2)
- •Baking soda
Tools
- •None required - hands only
Step-by-Step Instructions
Turn Off the Disposal
Flip the switch on your garbage disposal to the OFF position and confirm the unit has stopped completely. Never put your hands near the disposal while it's running or even when it's simply turned on. It's also a good idea to unplug the unit at the outlet for extra safety, or flip the breaker switch if you're uncomfortable reaching the outlet.
Pro Tip: Wait 10-15 seconds after flipping the switch to ensure the blades have come to a complete stop before proceeding.
Gather Your Cleaning Supplies
Collect a bowl of ice cubes, several fresh lemon or lime peels or citrus fruits, and have your sink plug or stopper nearby. These natural ingredients will help break down buildup and eliminate odors without using harsh chemicals. Make sure you have easy access to all materials before you begin.
Pro Tip: If you don't have fresh citrus, white vinegar or baking soda can be used as effective alternatives for freshening the disposal.
Feed Ice Into the Disposal
Turn the disposal back ON and carefully drop ice cubes one at a time down the drain, allowing each cube to process completely before adding the next. The ice will help dislodge stuck food particles and grease buildup on the blades and walls. Continue until you've fed all the ice through, then turn the unit OFF.
Pro Tip: Feed ice slowly rather than all at once to prevent jamming and ensure thorough cleaning of the entire chamber.
Grind Citrus Peels
Turn the disposal back ON and drop fresh lemon or lime peels down the drain one at a time, allowing them to grind completely before adding more. Citrus peels will freshen the disposal naturally and leave a pleasant scent in your sink. Continue until all peels have been processed, then turn OFF the disposal.
Pro Tip: Cut larger citrus fruits into quarters to prevent jamming and ensure better grinding action.
Run Hot Water Through the Disposal
Turn the disposal back ON and run hot water from the tap through the drain for 30-45 seconds while the unit is running. The hot water helps flush away any remaining particles and washes away debris loosened by the ice and citrus grinding. Once you're done, turn OFF the disposal and allow it to stop completely.
Pro Tip: If your hot water isn't very hot, boil a kettle of water and carefully pour it down the drain after turning off the disposal for even better cleaning.
Clean the Splash Guard
Reach up inside the drain opening and grasp the rubber splash guard (the rubber baffle at the entrance of the disposal). Pull it out gently and rinse it thoroughly under warm running water, using your fingers or a sponge to remove any buildup, slime, or debris trapped underneath. Replace it securely once it's clean.
Pro Tip: Use an old toothbrush to scrub the underside of the splash guard where debris often accumulates, then rinse well.
Deodorize with Final Rinse
With the disposal OFF, sprinkle about one tablespoon of baking soda directly into the drain opening. Turn the disposal ON briefly to activate it with the baking soda, then run hot water through for another 30 seconds while it's running. Turn OFF the disposal and let it sit for a few minutes before running water one final time to rinse thoroughly.
Pro Tip: For extra freshness, mix baking soda with a few drops of dish soap to create a mild paste before pouring down the drain.
Test for Proper Operation
Turn the disposal ON one final time with the cold water running to ensure it's operating smoothly and draining properly. Listen for the normal grinding sound and check that water flows freely down the drain without backing up. If everything sounds and drains normally, you're finished.
Pro Tip: If you notice unusual sounds, slow draining, or any odors remaining, mark this disposal for more thorough cleaning in another week.
