Method and composition for the preservation of film

Abstract

The present invention provides a non-evaporating lubricant and cleaner formulation that protects all types of film by forming a slick protective coating that reduces or eliminates dirt, scratches and static charges. An embodiment of the present invention comprises an organic mixture of greater than ninety-five percent (95%) aliphatic hydrocarbons. A preferred embodiment of the present invention comprises aliphatic petroleum naphtha, aliphatic petroleum distillates and petroleum base oil.
