I used to use "glass magic" but it is no longer at local stores. it is wonderful to keep glasses sparkling clear. i use good detergent (typically powder cascade) and the rinse-aid in the dispenser. i have tried using water pre-heat, too. still....glasses are cloudy.
calgon powder did not work, as suggested by the "glass magic" people. i can buy it online, but wondered if there is a (cheaper) remedy?
