This said you can put orange peels down your garage disposal and it made it smell nice . I asked what I shouldn't put mine and I was told no bananas peels or bones , I never was told not to put pasta down it , that is new to me. I had put small pieces of chicken fat down mine by mistake and that won't go down and it will made it smell really bad . Carrot peels is new to me too , I been putting this down mine for years and had no trouble .
