You can clean away water residue on a refrigerator water dispenser using a common household product that is safe for human consumption. Minerals in water often leave deposits that constrict the flow of a refrigerator dispenser. Clearing this build-up of residue from the dispenser nozzle returns the dispenser to the maximum flow rate. It only takes a few minutes to get a refrigerator water dispenser back to peak operating condition so you can quickly dispense clean, cool glasses of water.

Skill level:

Things you need

  • 1 cup distilled white vinegar
  • Shallow baking dish
  • Bottle brush
  • Flashlight
  • Toothbrush
  • Damp sponge
  • Glass

  1. 1

    Pour the distilled white vinegar into the shallow baking dish and dip the last three inches of bristles on the bottle brush into the vinegar.

  2. 2

    Point a flashlight at the refrigerator water dispenser nozzle from the underside. Slowly insert the vinegar-dipped bristles of the bottle brush for a couple inches or until you reach resistance. Spin the brush as you slowly pull it out.

  3. 3

    Dip the bottle brush into the vinegar again and repeat the insertion process until nothing comes out when you pull the brush from the nozzle.

  4. 4

    Wet the bristles of an old toothbrush in the vinegar and scrub away the water residue on the refrigerator water dispenser. Use a circular motion while applying light to medium pressure. Get the bristles of the toothbrush wet again if they dry out before all the cleaning is done.

  5. 5

    Wipe down all the cleaned surfaces on the refrigerator water dispenser with a damp sponge. Dispense and pour out two full glasses of water to wash away any vinegar flavour.

Tips and warnings

  • Check the water filter to see if it may need to be replaced or is being bypassed when water deposits build up on the dispenser quickly after it has been cleaned. Read the owner's manual for the specific model of refrigerator you are using to get the correct filter or turn the switch to run water through the existing filter.
