A dull or slow garbage disposal can be easily sharpened by running ice cubes through it.

Clean the garbage disposal of all nasty smells and sharpen the blades too by throwing in a few ice cubes while it is running. It works! Do it on a regular basis to keep the disposal in good shape.
I was just wondering if it is OK to periodically put a few ice cubes down the garbage disposal and run it? Would it clean and sharpen the blades?
