Eliminating Foul Odors from Your Kitchen Sink

That unpleasant sewage or rotten food smell emanating from your kitchen sink, despite appearing clean, can be a common issue. Flushing water or running the garbage disposal might not always solve the problem. Here’s how to tackle the odor at its source:

  • Debris Buildup: The primary culprit is often debris that has collected inside the garbage disposal’s rubber flapper or other hidden areas of the disposal.

  1. Clean the Rubber Flapper:

    • Safety First: Ensure the disposal is turned off before cleaning.
    • Wipe the Flapper: Use a coarse rag and detergent to wipe the underside of the rubber flapper inside the disposal.
    • Caution: Be careful not to insert your hand or the rag too far into the disposal. Focus on rubbing the underside of the flap.
  2. Remove and Clean the Flapper (If Possible):

    • Check Design: Some disposals allow for removal of the rubber flapper for easier cleaning.
    • Removal: Typically, the flapper is held in place by a slot around the edges. Gently remove it for thorough cleaning.
  3. Ice Cleaning:

    • Run Disposal: Turn on the disposal.
    • Add Ice: Dump a few pounds of ice into the running disposal.
    • Action: The ice chunks will bounce around inside, breaking away built-up debris.
  4. Citrus Refresh:

    • Add Citrus Peels: With the disposal still running, throw in a few lemon or lime peels.
    • Benefits: Citrus peels are tough and help to further break away debris. They also leave a pleasant, fresh scent.
