Silica film or etching (silica film is a milky, rainbow- colored deposit; etching is a cloudy film)
Water chemical reaction with certain types of glassware – usually caused by some combination of soft or softened water, alkaline washing solu- tions, insufficient rins- ing, overloading the dishwasher, and heat of drying.
It may not be possible to prevent problem, except by hand washing. To slow this pro- cess, use a minimum amount of detergent but not less than 1 tablespoon per load.
Use a liquid rinse agent and underload the dishwasher to allow thorough rinsing. Silica film and etching are permanent and cannot be removed. Use the Air Dry option.
