How to clean the white buildup off a dishwasher filter
The fibrous white coating on the dishwasher filter is usually a buildup of mineral deposits and undissolved detergent residue left behind after wash cycles. Removing and cleaning it requires taking the filter assembly apart properly, which stops the film from clogging the system and causing poor cleaning performance.
