There's an Odor Coming From Disposal

A garbage disposal odor is usually the sign of food buildup. It's an easy fix.

Written Directions

An odor from the disposal is usually a sign of food buildup, caused by insufficient water flow during and after disposal use.

Materials Needed

Scouring Pad
Baking Soda



  • Over time, food particles may accumulate in the grind chamber and baffle. Do not stick your hand in the disposal at any time.

Turn off power.

Turn off the disposal and disconnect the power supply.


Clean the baffle.

Reach through the sink opening and clean the underside of the baffle and inside the upper lip of the grind chamber with a scouring pad.


Fill the sink with water.

Place the stopper in the sink opening and fill the sink halfway with warm water.


Mix baking soda and water.

Mix 1/4 cup of baking soda with water in the sink. Turn on the disposal and remove the stopper from the sink at the same time to wash away loose particles.

Still Not Working?

Disposals may also be cleaned with Disposal Care® cleaner, which can be purchased on the InSinkErator online store.

Tips For Success

  • Run disposal along with a moderate flow of cold water. Continue to run cold water for a few seconds after grinding is complete.
  • Avoid using hot water when grinding food waste. It is OK to drain hot water into the disposal between grinding periods.
  • Never pour grease or fat into your disposal or drain.
