| Do not use abrasives on stainless steel or silver. |
| Distortion of plastics |

| of glass |
|
| To remove cloudy film, try a vinegar rinse: |
|
|
|
| • Wash and rinse load as usual. |
|
|
|
| • Remove all metal items from dishwasher. Do not |
|
|
|
| add detergent. |
|
|
|
| • Pour 2 cups of vinegar into a bowl and set it on |
|
|
|
| bottom rack. |
|
|
|
| • Run dishes through an entire wash program. If |
|
|
|
| the vinegar rinse does not work, repeat process |
|
|
|
| substituting ¼ cup of citric acid crystals (available |
|
|
|
| at most drug stores) for the vinegar. |
|
|
|
|
|
|
|
|
| If vinegar or citric acid rinse does not remove film, |
|
|
|
| the cloudiness is "etching". This is permanent. To |
|
|
|
| prevent etching, if you have soft water, try using |
|
|
|
| only 1 teaspoon of recommended dishwasher |
|
|
|
| detergent. |
|
|
|
| Use a good quality dishwasher detergent and rinse- |
|
|
|
| aid. Do not overload dishwasher. Water should |
|
|
|
| circulate freely to assure adequate rinsing and |
|
|
|
| draining. |
|
|
| Rinse aid used with soft water | Set rinse aid levels to minimum. |
