Why garbage disposals get dirty

Garbage disposals deal with food scraps every day, but they do not magically stay clean just because water runs through them.

  • food residue
  • grease
  • organic gunk
  • odor-causing particles
  • sludge clinging to internal surfaces

Signs your garbage disposal needs cleaning

  • the sink area smells bad
  • there is a lingering sour or rotten smell
