Why is my garbage disposal system emitting an odor, and how can I prevent this?

The odor from your garbage disposal system may be caused by food waste accumulated in the disposal unit or the drainpipe. To prevent this, make sure to run cold water for at least 15 seconds after using the disposal to help flush out any remaining food particles. You can also periodically clean the disposal by grinding ice cubes and citrus peels or vinegar to help remove any buildup. Avoid putting non-food items, fibrous foods, or oils and fats down the disposal, as these can contribute to clogs and odors.
