Garbage disposal emits a strong rotten or sewer-like odor even when not in use.

Safety note: Do not use harsh chemical drain cleaners in a disposal; they can damage components and create fumes.

• Step 1 – Clean splash guard: With power off, remove the rubber splash guard if it is removable. Scrub both sides with hot, soapy water and a brush. If non-removable, scrub in place with a long-handled brush.
• Step 2 – Clean chamber: Pour a mixture of baking soda (1/2 cup) followed by white vinegar (1 cup) into the disposal. Allow it to foam for 5–10 minutes.
• Step 3 – Ice and salt cleaning: Fill the disposal with ice cubes and add 1/4 cup of rock salt. Run cold water and briefly operate the disposal to scour the grind ring.
• Step 4 – Flush with hot water: Run hot water for several minutes to rinse away loosened debris.
• Step 5 – Deodorize: Grind small citrus peels (lemon, orange) with cold water to leave a fresh scent.
• Step 6 – Maintain: Regularly flush the disposal with plenty of water after use and avoid leaving food waste sitting in the chamber.
