While composting organic matter is the best thing to do with food waste, sometimes you end up putting some food down the drain. For your garbage disposal to work properly, never run hot water with the disposal. Hot water can liquefy fats, and when those liquefied fats hit cold water later, they begin to congeal and can clog the drains. To deodorize and disinfect, avoid bleach. Instead, use all-natural borax powder, which neutralizes mold and mildew on contact.
