A white film on	This problem is likely caused	• To remove the white film, run your dishes through a dishwasher cycle with
glassware, dishware	by a low quality phosphate-free		citric acid. Use a WD35X151 citric acid kit found online. Otherwise, use Lemi
and the interior	dishwasher detergent		Shine (WX10X10019) found at your local grocery store.

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. Alternatively,

a vinegar rinse may be used. Pour 1 cup of vinegar into dishwasher just after the detergent cup opens and let the dishwasher complete its cycle.

This may be repeated several times a year as needed

The use of a rinse agent such as Cascade® Complete Rinse Aid may help minimize a repeat build up of film. Also, the use of a highly rated detergent such as Cascade® Platinum Pacs will help prevent film build-up.
