Yeah, the ice cube thing always seemed a bit iffy to me too. I mean, I've tried it a few times, and while it does seem to help knock loose some of the gunk, I doubt it's actually sharpening anything. Like you said, disposals don't really have blades like knives—more like blunt grinders.
Funny you mentioned the splash guard though... I remember one time my disposal smelled so bad I was convinced something had crawled in there and died. After trying all the usual tricks (lemons, ice cubes, vinegar), I finally popped out that rubber guard and... yikes. Let's just say it was a horror show underneath. Scrubbed it down with hot soapy water and an old toothbrush, and the smell vanished almost immediately.
So yeah, baking soda and vinegar are solid go-tos for regular maintenance, but definitely check under that splash guard every now and then. It's sneaky how gross it can get without you even noticing.
"Scrubbed it down with hot soapy water and an old toothbrush, and the smell vanished almost immediately."
Yeah, that splash guard is definitely a hidden culprit. Ever checked the underside of the disposal flange itself? Sometimes gunk builds up there too, and it's easy to overlook. Also, just a cautious reminder—always unplug or shut off the breaker before poking around in there. Better safe than sorry... disposals can be sneaky even when they're off.
I've seen some gnarly stuff hiding under that flange—it's like a secret swampy lair down there sometimes. Another sneaky spot is the rubber gasket itself. I once had tenants complain about a persistent smell, and after some detective work, discovered the gasket was harboring a colony of nasty gunk. Removing it and soaking in vinegar overnight did the trick.
Also, tossing in some ice cubes and lemon peels every now and then helps keep the blades clean and freshens things up a bit. But yeah, safety first—never hurts to double-check that breaker. I've heard enough horror stories from folks who assumed their disposal was "off" but got an unpleasant surprise. Better paranoid than sorry...
"Another sneaky spot is the rubber gasket itself."
Yeah, that gasket is a real troublemaker. I've had similar issues, and vinegar definitely helps. Another trick I've found useful is sprinkling some baking soda down there, followed by a good splash of white vinegar—let it fizz for a bit, then flush with hot water. Clears out the funk pretty well. And you're spot-on about the breaker... learned that lesson the hard way once, never again.
I've tried the baking soda and vinegar trick too, but honestly, it only seemed to mask the smell temporarily for me. Eventually, I realized the real culprit was deeper down in the disposal blades themselves. Have you ever tried tossing in a handful of ice cubes and some coarse salt, then running it for about 30 seconds? It scrubs off all that hidden gunk pretty effectively. Might be worth a shot if the gasket cleaning doesn't fully solve it...
