Wive's tale or not, the old adage is ice cubes, fruit pits, and
steak bones will sharpen a disposer. It won't cost much to try,
it won't harm anything, and worst case, will require replacement.


I've used ice cubes for years in many disposers. I personally don't believe
it sharpens. I just believe it clears the accumulated small bits and pieces
that won't go down and are stuck in a place where the disposer grinding
can't get at it.
