Dishwashing - Water Spotting & Rack Marks

Spots are caused by dissolved salts and minerals remaining on glasses and flatware after the water evaporates. This usually happens in hard water, but can also happen in mechanically softened water. POSSIBLE CAUSES: Not enough dishwasher detergent. Increase the amount of dishwasher detergent according to water hardness. Not using a rinse aid. Use a rinse aid, such as Jet Dry or Crystal Clear according to the dishwasher's User's Guide. Low water temperature. Turn up the setting on the water heater or use a water heating option regularly. (For optimum results, water heating dishwashers require a minimum of 120° F. inlet water and regular use of heating options. Non-water heating dishwashers need 140°F. inlet water for optimum results.)
