I always use the old baking soda I take out of the fridge or freezer and put it down the disposal. I add vinegar to make it bubble up and get to every part inside. This keeps it smelling clean and fresh. When I turn it on to rinse, I add a cup or two of ice cubes and let it run until the cubes are gone. I understand this keeps the blades sharp.
