smells
I grind everything but the kitchen sink, ha. Corn cobs go down fine, the only thing I don't grind is corn husks. They take forever and are more pain than its worth. Often in my ISE I will have a ball of corn silk left in the machine when I'm done.
That's a good idea Jon, about the ice. That would be good way to clean out smelly machine. I haven't had as many disposals as Wes, but I have had had an uncountable number. The only ones I ever had an odor problem with were the Annaheim Manufactured units (SinkMaster, New GE's, Franke, and a host of other names.) It's been a few years since I've had an Annaheim unit so I don't know if they ever corrected the problem.
Annaheims grind very well, but they used a plastic detergent shield in the lower grind chamber. Bone bits, etc. would scratch this and bacteria would grow in there and phew...ooftah. So I was always running bleach down the unit to freshen things up. Anyone have an Annaheim unit now and have this problem? Just curious if they ever changed that.
Never had an odor problem with a vintage GE, Maytag, ISE (new or vintage), pre-ISE Viking, Universal Waste King or Westinghouse.
By the way, Viking no longer manufacturers disposers. They bought the design rights for the original Hobart KitchenAid designed disposer (with the Wham-Jam breaker

) and manufactured it themselves. Then they gave up self manufacture and contracted ISE to do it for them, but kept the same basic design. As of last year they quite the disposer market altogether. Too bad.
Right now I have a 1991 Sears (ISE) batch-feed in the main kitchen and a GE Series wound "Pirahna" in the kitchenette. I found the Sears on Craigslist. It was NOS and had never been opened. It is a top of the line batch feed model. I bypassed the cover start switch and use it like a continuous feed powered by the wall switch.
But the nice thing about the older batch feed models was that most of them had a much deeper and larger grind chamber than their continuous feed counterpart. Most corn cobs I don't have to break in half first because they fit right down there, as do chicken legs bones, etc.
In my units with the shallower grind chambers, sometime a long chicken leg or cob will slightly stick out of the top and twirl around and splash until the unit gets it ground enough to fully pull it into the chamber. So usually I broke cobs in half to stop the splashing. But it's really cool now just to drop the whole cob straight in. I did add a splash guard as batch feeds don't come with, or need one.
