Soft Water Etching

If the cloudy film is not removed after soaking in

vinegar (previous procedure), then the condition is etching. This permanent film occurs in unusual conditions 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 any dish- washer with the combination of soft water (espe- cially mechanically 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 p. 7.)

2.Lower the water temperature to 120°F. (See p. 4.)

3.Avoid using the Heat Dry drying option.

4.Do not manually pre-rinse dishes before load- ing in dishwasher. Pre-rinsing prior to loading to remove all food soil aggravates etching,

Rust

Sometimes the dishes or the interior of the dish-

washer may turn a brown, red or black color if iron or manganese is in the water. To remove discol- oration from the dishwasher interior, dishes and

glassware (no metal items):

1.Select a rust removing compound, such as RoVer Rust Remover. It is available from dealers by using Part No. 057961.

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.

You can help save energy if you:

1.Wash full loads. Running a half-filled dish- washer uses the same amount of electricity and hot water as a fully loaded machine.

2.Do not pre-rinse normally soiled dishes. Se-

lect the correct cycle for the load and use the recommended amount of detergent for good washing results without hand rinsing.

3. Load correctly for best washing results. Incor- rect loading may cause poor washing and the need to prewash all or part of the load.

4.Use the Light cycle when dishes are lightly soiled. It uses less hot water and energy than other cycles.

5.Most models - fan dry dishes (without heat) when you don'tneed them dried quickly. 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 the day. Check with your utility company to see if off- peak rates exist.

The interior is normally self-cleaning. Occasion- ally check the bottom of the dishwasher tub and clean out pieces of food which may collect there.

Periodically clean the bottom edge of the dish-

washer door liner. Food and liquids drip onto this area when the dishwasher is loaded.

If you notice an odor in your dishwasher, it may be due to a strong "chemical" or chlorine odor from the dishwasher detergent. Using a different deter- gent, especially a lemon scented one, will prob- ably eliminate the odor. In some instances the smell of the rinse aid may be strong. Purchase a fresh package and see if it is better. Lastly, if the dishwasher is run only every couple of days, an odor may develop. Use the Rinse & Hold cycle

daily to remove any food soil that may cause an odor.
