Why does my garbage disposal smell bad and how can I get rid of the unpleasant odor?

Your garbage disposal may smell bad due to food particles and debris stuck in the unit, leading to bacterial growth and odor. To get rid of the unpleasant smell, you can try running ice cubes, citrus peels, and baking soda through the disposal, followed by flushing it with hot water and vinegar. Regularly cleaning and maintaining your garbage disposal can help prevent future odors.
