� Soft Water Etching If the cloudy fihn is not removed after soaking in vinegar (previous procedure), then the condition is etching. This permanent film occurs in unusual couditions under which the surface of the glass is pitted or eroded. It is permanent. In the beginning stages, etching may be identified by a "rainbow" look--shades of blue, purple, brown or pink may be seen when the glass is held at an angle to the light. In advanced stages the surface of the glassware appears frosted, spotted or cloudy. Certain types of glassware will etch in may dishwasher with the combination of soft water (especially meehanieally softened), an excessive amount of detergent, heat and prerinsing. There is no relationship to the cost or quality of the glass. To prevent: 1. Adjust the amount of detergent to the degree of water hardness (see page 6). 2. Lower the water temperature (see page 3).

2. Start empty dishwasher on Rinse & Hold or rinse portion of the cycle. During fill, open the door and add 1/2 cup RoVer Rust Remover to the water. Allow the dishwasher to complete the cycle. 3. Follow with a detergent wash. The only permanent solution is to install special filters which can remove iron and manganese from the water.

Energy Saving
You can help save energy" if you: 1. Wash fidl loads. Running a half-filled dishwasher uses the same amount of electricity and hot water as a fully loaded machine. 2. Do not pre-rinse normally soiled dishes. Select the correct cycle for the load mad use the recommended amount of detergent for good washing results without hand rinsing. 3. Load correctly for best washing results. Incorrect loading may cause poor washing and the need to prewash all or part of the load. 4. Use the Light/China cycle when dishes are lightly soiled. It uses less hot water and energy than other cycles. 5. Fan dry"dishes (without heat) when you don't need a rapid drying cycle. Allow longer drying times (overnight). 6. Use your dishwasher during off-peak hours. Local utilities recommend this to avoid heavy usage of energy at certain times of day. Check with your utility company to see if off-peak rates exist.

3. Do not manually prerinse dishes before loading in dishwasher. Prerinsing prior to loading to remove alI food soil aggravates etching, � Rust Sometimes the dishes or the interior of the dishwasher may tuna a brown, red or black color if iron or manganese is in the water. To remove discoloration from dishwasher interior, dishes and glassware (no metal items): 1. Select a rnst removing compound, such as RoVer Rust Remover. It is available from Maytag Parts Distributors by using Part No. 57961.
