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