At a Glance

Difficulty: Beginner
Time Required: 15–60 minutes per session
Frequency: Monthly for routine care, annually for inspections
Estimated Cost: DIY $0–$50 (cleaning supplies); Pro $100–$300 (service/repairs)

Safety Warnings

Always disconnect power at the circuit breaker before inspecting or working on the disposal. Do not rely on the sink switch alone.
Never put your hand or fingers into the disposal. Use tools (hex wrench, tongs, or pliers) to remove jams.

Step-by-Step DIY Guide

You MUST provide at least 5 to 7 distinct steps. Do NOT group multiple different maintenance tasks into a single step. Each task must be its own dedicated Step.

Step 1: Power Off and Confirm

Turn off the garbage disposal at the wall switch, then switch off the corresponding circuit breaker. Test the switch to confirm the unit has no power before proceeding.

Step 2: Clear Visible Debris and Clean the Splash Guard

Use tongs or a flashlight and a small brush to remove visible food debris from the splash guard and sink opening. Remove the rubber splash guard (if removable) and wash it with warm soapy water.

Step 3: Manually Rotate the Impeller to Free Jams

Locate the hex socket at the bottom of the disposal. Insert the appropriate hex (allen) wrench and rotate back and forth to free any jammed impeller. If the unit lacks a hex slot, use a long wooden spoon from above—never your hand.

Step 4: Grind Ice and Coarse Salt to Clean Grinding Components

Pour a tray of ice cubes and 1/2 cup coarse rock salt into the disposal. Run cold water and turn the disposal on briefly to break up buildup on the impellers and help remove grime.

Step 5: Deodorize with Baking Soda and Vinegar or Citrus

Sprinkle 1/2 cup baking soda into the disposal, then pour 1 cup white vinegar. Allow it to fizz for 5–10 minutes, then rinse with hot water while running the disposal. Alternatively, grind citrus peels for a fresh scent.

Step 6: Inspect and Tighten Mounting and Drain Connections

Look under the sink for drips, loose fittings, or worn gaskets at the mounting flange, drain trap, and dishwasher inlet. Tighten slip-nuts and mounting bolts by hand or with a wrench; replace worn gaskets or hoses as needed.

Step 7: Restore Power and Test Operation

Restore power at the circuit breaker. Run cold water and switch the disposal on. Listen for abnormal noises, ensure it runs smoothly, and confirm there are no leaks while operating.

When to Call a Pro

Persistent humming or stalling after manual unjamming
Visible leaks from the unit, mounting flange, or drain that you cannot stop by tightening
Burning smells, tripped breakers, or electrical issues
Repeated clogs, poor drainage after checking trap and drain line
Corrosion or mechanical damage to the disposal housing

Frequently Asked Questions

How often should I run my Moen garbage disposal?

Run the disposal whenever you generate soft food scraps that need grinding. Always run cold water during grinding and for 15 seconds after to flush solids into the drain.

What should I never put in a Moen garbage disposal?

Avoid fibrous foods (celery, corn husks), grease and oil, bones, coffee grounds in large amounts, and starchy foods (rice, pasta) that can form pastes and clog the drain.

How do I stop my disposal from smelling?

Clean the splash guard and grind ice with coarse salt monthly, and use a baking soda and vinegar treatment or grind citrus peels to remove odors.

My disposal hums but won’t turn. What should I do?

Turn off power at the breaker, use the hex wrench to free a jam, and press the reset button on the bottom of the unit. If it still won’t run, call a professional.

Can I use bleach to clean my garbage disposal?

Avoid concentrated bleach. Small amounts diluted in plenty of water are not ideal. Use baking soda, vinegar, or mild dish soap for routine cleaning instead.

When is it time to replace the disposal?

Consider replacement if the unit leaks from the housing, has persistent electrical problems, extremely loud operation, or frequent failures despite professional repairs.
