A garbage disposal can start to smell when food residue builds up on the grinding parts and in the drain. A cleaner will not fix a jam or a clogged pipe, but regular use can help control odor and film. Cleaners come as tablets, powder packets, capsules or foam.
The six products below are made for disposals. Details come from the product listings, and we have not used these cleaners ourselves. Read the label for directions, and check whether the product is safe for septic systems if you have one.
