It usually starts with a whiff—something sour, swampy, or just… off. You take out the trash, wipe the counters, run the dishwasher, and yet that funky smell in your kitchen won’t go away. The culprit? Most likely, your garbage disposal.

If you’ve noticed a nasty odor coming from your sink, you’re not alone. As a plumber in Salt Lake City, we’ve seen (and smelled) it all. A smelly garbage disposal isn’t just annoying—it can be a sign that your unit needs a little TLC. In this blog, we’ll break down why garbage disposals start to stink, how to clean them properly, and when it’s time to call in a professional.
Why Garbage Disposals Smell in the First Place?
Your garbage disposal is built to grind up food waste and send it down the drain. But over time, small particles of food, grease, and sludge can stick to the inside walls of the disposal chamber, the splash guard, and the underside of the blades (technically called impellers).
These scraps don’t wash away easily. Instead, they start to rot. Bacteria builds up. Odors follow. And that’s when your kitchen starts to smell like a science experiment gone wrong.
It gets worse if the splash guard isn’t cleaned regularly—this rubber flap is often overlooked during regular cleaning, even though it’s one of the smelliest spots in the system.
Quick Fix: How to De-Stink Your Garbage Disposal?
Here’s a simple cleaning routine that many of our customers use between service calls. It’s effective, budget-friendly, and doesn’t require any fancy tools.
Step-by-step Cleaning:
- Unplug the unit. Safety first—always turn off the disposal at the switch and unplug it from under the sink.
- Scrub the splash guard. Pull the rubber guard up slightly and clean both sides with a sponge and dish soap. A toothbrush works well for getting into the folds.
- Use ice and salt. Toss in 2 cups of ice and a cup of coarse salt (rock or kosher works best). Run cold water and turn the disposal on. This will help scrape off gunk and debris.
- Flush with hot water and soap. Fill the sink halfway with hot water and a few drops of dish soap. Pull the drain plug and run the disposal to flush everything out.
- Optional: Freshen with citrus. Grind up a few lemon or orange peels. The natural oils help freshen the unit and break down grease.
If your garbage disposal still smells after all that, it might be time to call a licensed plumber for a deeper inspection.
When DIY Isn’t Enough?
Sometimes, no matter how much scrubbing and flushing you do, the odor lingers. This could mean there’s a buildup deeper inside the system, or a bigger issue with your kitchen plumbing.
Here are a few signs it’s time to call in a garbage disposal professional plumber:
- Persistent smells even after cleaning
- Strange noises (grinding, rattling, or humming)
- Slow drainage in your sink
- Water leaking under your sink
- The unit won’t turn on or reset
