What Not to Dispose
Any food waste that has the potential to shred or deteriorate in such a way to clog the drain or wrap around the blades should not be put down a garbage disposal.
Vegetables with tough skins or peels
When the garbage disposal turns on and shreds these skins and peels, they cut up into fibrous strips that wrap themselves around the blade and wheel. This chokes the motor and clogs the drain just as hair down a shower drain.
Food materials that can turn to paste
Pipes are clogged when grease, egg shells, coffee grounds, pasta, rice, beans and potatoes bloat with water and turn into a gluey paste that sticks to the insides of pipes and drains. Dispose as much of these materials in the trash.
Corrosive drain cleaners
Tough drain cleaners with corrosive properties use fine sand to scrape the insides of the drainpipes clean. Unfortunately, these sands also turn into a paste inside the disposal that can destroy the pipes by clogging them instead of cleaning them.
