The Short Answer
Scrub the rubber splash-guard flaps (unplug the unit first — that is where most of the smell hides), grind a cup of ice with coarse salt to scour the chamber, then grind citrus peels to deodorize, and finish with a baking-soda-then-vinegar flush and cold water. Do it every week or two, run cold water after every use, and keep grease and fibrous foods out.
Where the Smell Actually Hides
People assume a smelly sink means a dirty drain, then pour cleaner down and wonder why nothing changes. The odour is almost always in the garburator, in three specific spots: the underside of the rubber splash guard (the flaps you push food past), a film of ground food coating the impellers and grind ring, and greasy residue in the chamber itself. Clean those three and the smell is gone — no drain cleaner required.
The Cleaning Methods
| Method | What It Does | How |
|---|---|---|
| Ice + coarse salt | Scours hardened food and gunk off the impellers and grind ring | Run a cup of ice and half a cup of salt with cold water for 15 seconds |
| Citrus peels | Cuts grease and leaves a fresh smell — the odour fix | Grind a few lemon or orange peels with cold water running |
| Baking soda + vinegar | Deodorizes and breaks down residue in the chamber | Half a cup of baking soda, wait 10 min, add a cup of vinegar, then flush with hot water |
| Dish soap + cold water flush | Rinses loosened debris fully out of the unit | A squirt of soap, cold water on, run 30 seconds after use every time |
| Splash-guard scrub | Cleans the rubber flaps where most of the smell actually hides | Unplug first, then scrub the underside of the guard with a brush |
“The number-one 'my disposal stinks' fix isn't a chemical — it's scrubbing the rubber splash guard nobody ever thinks to lift.”

What to Never Put Down It
Cleaning keeps a garburator fresh; the wrong scraps are what break it. Keep out grease and cooking oil (they congeal into clogs), fibrous foods like celery, corn husks, and onion skins (they wrap the impellers), starchy items like potato peels and pasta (they turn to a paste that seizes it), and bones, fruit pits, and large quantities of coffee grounds or eggshells. And never use chemical drain cleaner — it can attack the seals. Avoiding those prevents most of the jams covered in our not-working guide.
One Safety Rule
Before your hand or a brush goes anywhere near the opening — to scrub the splash guard or fish out a stuck item — unplug the unit or switch off its breaker. A garburator that starts with a hand inside is exactly the injury this rule exists to prevent. If something is jammed too deep to reach safely, that is a job for our garburator repair team in Sherwood Park, who clear it with the proper tools.
Cleaning Questions, Answered
How do I clean a smelly garburator?
The smell usually lives in three places: the rubber splash guard, the grind chamber, and food film on the impellers. Scrub the splash-guard flaps (unplug the unit first), grind ice and coarse salt to scour the chamber, then grind citrus peels to deodorize. A baking-soda-then-vinegar flush finishes it. Doing this every week or two keeps the smell from ever coming back.
Can I put vinegar and baking soda down my garbage disposal?
Yes — it is one of the safest and most effective cleaners. Pour in about half a cup of baking soda, let it sit ten minutes, add a cup of white vinegar, let it fizz, then flush with hot water. It deodorizes and breaks down greasy film without any harsh chemicals that could damage the seals.
What should you never put in a garburator?
Grease and oil (they congeal and clog), fibrous foods like celery and corn husks (they wrap the impellers), starchy items like potato peels and pasta (they turn to paste), bones and fruit pits (they jam it), coffee grounds and eggshells in quantity (they build sludge), and absolutely no chemical drain cleaners. Avoiding these prevents most of the jams and clogs we get called about.
