Garbage disposal emits a persistent foul odor even after running with water.

Safety first: Turn off the disposal before cleaning. Do not use your bare hands inside the chamber.

• Clean the splash guard: Remove the rubber baffle/splash guard and scrub both sides with hot, soapy water. Food often accumulates on the underside.
• Scrub the chamber: Use a long-handled brush with dish soap to scrub the inside walls of the Maxmatic chamber and around the shredder ring.
• Deodorize: Grind a tray of ice cubes with a cup of baking soda and cold water, then flush with hot water. You can also grind small citrus peels for a fresher smell.
• Flush the drain: Run hot water for several minutes to help clear grease from the drain line.

If odors persist, the smell may be coming from further down the drain or from a dirty dishwasher connection; additional plumbing cleaning may be required.
