Garbage disposal odors: clean the removable splash baffle safely
Disconnect power first, wash only parts that the manual identifies as removable, and never reach into the grinding chamber.
Some sink-mounted food waste disposers have a removable splash baffle that traps food residue and odors. InSinkErator describes periodic cleaning of removable baffles on compatible models. Never put a hand inside the grinding chamber, even when the appliance is off; first check the model instructions and isolate its power supply.
