The “Sink Funk” is Real: A Simple Fix for Your Stinky Garbage Disposal
We’ve all been there. You’ve scrubbed the counters, took out the trash, and even did the dishes, but there is still a lingering, “locker room” smell wafting through the kitchen.
You try the old-school tricks. You toss some lemon wedges down the disposal, or maybe a handful of ice cubes. It smells great for about ten minutes, but then the citrus fades and the “sink funk” returns.
If you’re looking for how to clean a stinky garbage disposal, the truth is, lemons are just a scented band-aid. They don’t reach the “sludge” hiding under the rubber splash guard where the real smell lives.
The Science of the Sludge
If you were to take a flashlight and look under the rubber splash guard of your disposal, you’d probably be horrified. That’s where the grease, food particles, and slime build up. Since the water from your faucet shoots straight down the middle, it never actually touches the underside of that guard or the top rim of the disposal chamber.
Essentially, you have a hidden colony of old leftovers living in your sink.
The “Lazy Pro” Solution: Glisten
I’m a big fan of keeping things simple. I have zero interest in sticking my hand down a dark hole with a toothbrush to scrub away slime. I’m always looking for things that are oddly useful, and Glisten Garbage Disposer Cleaner fits the bill. It’s not just soap; it’s a deep-cleaning foam that expands to reach the spots you can’t see.
It’s not some magic potion, but it is a clever bit of engineering. Instead of just liquid soap that washes away instantly, this stuff creates a massive, blue foaming action. Because it’s a foam, it expands upward and outward, reaching the underside of the splash guard and the sidewalls—the exact spots your lemons can’t touch.

How to Use It
If you’re looking for how to clean a stinky garbage disposal without taking the whole thing apart with a toothbrush, this is the 90-second fix.
The instructions on the bag are okay, but if you want it to actually work, there is one trick: Less is more when it comes to water.
- Get it Hot: Run hot water in the sink next to the disposal for a minute to get the pipes warm.
- The Trickle: Turn the water down to a tiny, pencil-thin trickle. If the water is too strong, it’ll just flush the foam away before it can scrub anything.
- The Packet: Drop one unopened packet into the disposal.
- The Show: Turn the disposal on. You’ll see a blue foam rise up into the sink. It’s a bit gross, but honestly pretty satisfying because you know it’s actually hitting the source of the smell.
- Rinse: Once the foam is gone (about a minute or two), rinse the sink and you’re done.
The Bottom Line– Is it going to save a broken motor? No. Is it going to fix a major plumbing clog? Definitely not. But if you want a solution that takes about 90 seconds and actually kills the “sink funk,” this is the best $10 you’ll spend this month.
At the end of the day, knowing how to clean a stinky garbage disposal doesn’t have to be a chore. It’s a simple, honest solution that actually gets the job done.
