Do Egg Shells Sharpen a Garbage Disposal?

Benefits

• Eggshells can be used as natural, abrasive cleaning agent. When placed in a garbage disposal, the eggshell's abrasive qualities may work to sharpen disposal blades and scour the walls of the disposal's chamber.

Drawbacks

• Many plumbers argue that eggshells may damage or clog garbage disposals when too many are added to the disposal at once. Smaller models have more trouble dealing with large quantities than larger models.

Considerations

• To effectively use eggshells to sharpen and clean garbage disposals without causing damage or clogs, drop one shell into the disposal at a time while running cold water. For added protection, crumble shells by hand to place less work on your garbage disposal.
