Have you ever clogged your garbage disposal to the point where you felt that you were going to have to buy a new one? Well before you do here's a little tip that will extend the life of your garbage disposal. First, look for the wrench that came with your disposer. It may be taped to the side of the unit or to the cabinet wall. It's a rod maybe 6 inches long and looks similar to a Allen/hex wrench. Next, stick the short end into the matching hole in the bottom center of the disposal and use the long end to turn it back and forth until you break free whatever's got the disposal stuck.
