The maintenance wax will restore the finish and afford protection. If surface rust does occur rub with wire wool and apply maintenance wax with a rag or brush. Inevitably when two areas of metal come into contact with each other an abrasive action is enacted, and sooner or later the wax surfaces are lost by the constant rubbing action. This is unavoidable during the operational activity of the article, so where obvious abrasive areas of moving parts are visible an occasional light oiling is recommended.
