What should we do to maintain the InSinkErator Evolution Excel properly?

The InSinkErator Evolution Excel, like all garbage disposals, benefits immensely from regular maintenance. Try cleaning the chamber once a week or every two week by grinding ice with slices of lemon or lime. Grinding ice creates a scouring effects on the components and citrus fruits like lemons help sanitize and freshen the chamber. To take it a step further, combining baking soda and vinegar can help attack stubborn buildup. Mix them up in the grinding chamber and leave it be for 20 minutes or so, then flush with water. Hot water is better if you have metal pipes.
