How do I clean white film from the inside surfaces of my dishwasher?
White film is caused by hard water minerals. To clean the interior, apply dishwasher detergent to a damp sponge while wearing rubber gloves. Do not use any type of cleanser other than dishwasher detergent because it may cause foaming or sudsing. Cascade® Automatic Dishwashing Detergent has been approved for use in all GE dishwashers.
