A garbage disposal is a useful piece of kitchen equipment. Many owners of a garbage disposal are unaware that there are certain items that should never be thrown into the sink where the garbage disposal is located.
Oil, Grease Or Animal Fat:
Oil, grease and animal fat should never put put into a garbage disposal. These elements turn into a solid as they cool and have the capacity to clog the disposal system and render it nonfunctional.
Most people throw all food down their garbage disposal but certain vegetables should never go into the system. Food items that have stalk or leaves will wind around the blade mechanism and potentially burn out the motor on the garbage disposal or clog the drain.
Noodles and Rice:
Everyone knows that pasta and rice expands when they become wet. Pasta or rice that is put into a garbage disposal will continue to expand over time. The expansion of the noodles or rice allow for the garbage disposal to become clogged requiring a plumber to fix the unit and unclog the kitchen drain. If pasta or rice does not clog the drain, they will eventually fill the trap system built into the garbage disposal causing the system to quit working.
Ground coffee gives the appearance of draining just fine when put into the garbage disposal. The problem with coffee grounds is that they settle into the trap of the garbage disposal which fills it up and will require a plumber to empty and fix.
Animal bones are the number one killer of garbage disposals. Disposals are just not made with enough strength to completely destroy animal bones. Trying to use the garbage disposal for disposal of bones will cause the motor to burn out or the blades to break. Fish bones are very small and may be put down a garbage disposal.
