Run cold water into the drain and turn on the disposal. Let it run for about 1 minute to be sure larger chunks of food are gone.
Turn the disposal off and fill the disposal with ice cubes.
Pour about 2 or 3 cups of baking soda into the disposal. This is the deodorizer.
Turn on the cold water and the disposal at the same time. The ice bits fly around the disposal, acting like little scrubbers, as the baking soda neutralizes the foul odors.
After the ice is gone, allow the water to run for about a minute longer.
