Glisten Dishwasher Magic powerfully removes limescale, rust, grease and other buildup caused by hard water, detergent and food residues. Over time, this buildup affects your dishwashers cleaning performance and can lead to the presence of harmful bacteria. Regular glisten dishwasher cleaner use keeps your machine amazingly clean, fresh and maintained. Unlike other machine cleaners, glisten cleans and disinfects even the hidden, vital and hard-to-reach areas. It is specially formulated to penetrate buildup and hard water impurities so they can easily be removed from your dishwashers water jets, tubes and pipes, while also disinfecting against harmful bacteria. Glisten, the only EPA-registered dishwasher cleaner and disinfectant, is safe for all dishwashers, plumbing and septic systems.
