Sub-Zero Ice and Water Dispenser Cleaning Instructions


  • Clean hard water stains and water lines from my ice and water dispenser?
  • What is the best product to clean the dispenser?
  • The glasswell grille finish is coming off
  • Dispenser cleaning to remove odor from dispenser model refrigerators


Use the Stainless Steel Exterior Cleaning Procedure for any stainless steel portion of the door dispenser.

  • The water line to the unit is either copper or PEX and a plumber might suggest how to clean them.
  • Inside the unit, there is nothing to clean nor should it require cleaning.
  • Calcium buildup in the ice chute may be cleaned with a 1:1 vinegar and water solution. Clean reachable area with a rag and the solution, then clean with a damp cloth.
  • If mold or other residue develops in the internal water lines or ice chute, contact Factory Certified Service to help with cleaning.
