3.  Removing stains from flatware.- The greatest single cause of corrosion to stainless steel flatware is food soil, especially from foods which are acidic.  The presence of lactic, tannic, tartaric, citric and other acids present in such foods as mayonnaise, fruits, fruit juices and

butter attack and remove the oxide film from stainless steel surfaces, causing

pitting or surface corrosion to take place.  The longer the food soil remains in contact with the flatware the greater the corrosion.  FLATWARE SHOULD BE PRESOAKED IN THE WASH SOLUTION AS SOON AS POSSIBLE AFTER USE.  The following

operating procedures should be followed for removing stains from flatware:

a.  Dissolve completely two ounces of hand dishwashing compound, FSN 7930-281-4731) for each one gallon of warm water (120°F to 125°F) in wash sink or some other suitable container.

b.  Place flatware in the wash solution for five minutes. DO NOT OVERSTACK FLATWARE.

c. Remove the flatware from the wash solution, and immediately wash it in a dishwashing machine using the recommended machine dishwashing procedures specified in Section III.
