1. Ice Cubes While ice cubes can still be used to clean the disposal grinding components, ice will usually melt before it cleans the grind chamber completely.
2. Citrus Fruit If your garbage disposal has a bad odor you can help to neutralize the smell by grinding a citrus fruit like lemons or oranges. Cut the fruit into wedges, turn the disposal on and put the wedges down one at a time along with a steady stream of cool water. The fruit rinds will help to clean the grind components while the citrus scent will provide a fresh smell. If you want use something harder than a citrus fruit you can cut a peach in half and place it down the disposal. And throw in the pit. The hard peach pit will help to dislodge any food waste that is stuck in the disposal.
