A simple rinse of the motor will suffice in most cases. Turn on the unit and run a stream of hot water through it for about 2 minutes. This is also the easiest way to eradicate odor. Some machines can be connected to a dishwasher for fuss-free cleaning. Every once in a while you may want to give the disposal a more thorough wash – just fill the sink with soapy water and let it pass through the unit to flush down loose debris.
