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, and even the dishwasher tub itself. 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.
- Automatic dishwashing detergents are now phosphate-free to comply with various state regulations that became effective July 1, 2010. The changeover in stores has been occurring gradually since late 2009.
- Use finish® Dishwasher Detergent Booster following the instructions on the package (can be purchased from GE Appliance Parts- part number WX10X10022 or at the local supermarket)
- Use Citric Acid following the instructions below (can be purchased from GE Appliance Parts- part number WD35X151 or at the local supermarket)
- Pour the citric acid in the detergent cup and close the cover.
- Place the filmed, but otherwise clean, glassware and dishware in the dishwasher. Leave silverware and other metal items out of the dishwasher.
- 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.
