Yellow or brown stains on dishes and/or dishwasher interior
|
Iron or manganese content in water supply.
|
After food soil is removed, wash dishes with citric acid crystals. Check
dishwasher manufacturer's instructions for amount to use and method. Do
not add detergent.
A liquid product is available to remove iron deposits from the dishwasher
interior; follow the package instructions.
To retard staining, use maximum amount of dishwasher detergent to keep
iron or manganese in suspension during the wash. Use a rinse additive
during the rinse.
|
If staining cannot be controlled, the only solution is in the
installation of iron removal equipment in the home water supply.
