"What is the difference between the Bone Crusher line and the Waste King Gourmet line of disposers?"
Sinkmaster has discontinued manufacturing the Bone Crusher line of disposers and replaced this line with the Waste King Gourmet line.

"My garbage disposer smells! Is there anything that I can do besides buying a new one?"
Generally the simple solution to this is to clean the disposer by having it grind up a few cups of ice and some table salt. This helps to cut the grease and slime off the sides of the disposer. Then flush it out with cold water followed by half of a lemon or lime to deodorize.
