Dishwasher - White Film on Glassware, Dishware and the Interior

A white, milky film on glassware, dishware and the interior of the dishwasher can be caused by phosphate-free dishwasher detergent. Detergents without phosphates can potentially leave a white film on glassware and other items, even the dishwasher tub itself. This white film is most often observed in hard water areas. Please note that “film” refers to a mineral build up and not etching as a result of using too much detergent.

 

How to remove the white film:

  • Use a high quality dishwasher cleaner, such as Cascade® Platinum™ Dishwasher Cleaner or Finish® Dishwasher Cleaner. Finish® Dishwasher Cleaner can be purchased from GE Appliances Parts using part number WX10X10209.

  • Use Citric Acid following the instructions below. Citric Acid can be purchased from many local supermarkets.

    1. Pour the citric acid in the detergent cup and close the cover.

    2. Place the filmed but otherwise clean glassware and dishware in the dishwasher. Leave silverware and other metal items out of the dishwasher.

    3. Turn the dishwasher on and let it run through a complete cycle without detergent. The glassware, dishware and dishwasher should come out film free and sparkly.

  • Use a vinegar rinse. Pour 1 cup of vinegar into the dishwasher just after the detergent cup opens and let the dishwasher complete its cycle. This may be repeated several times a year if needed.
