Abstract

A process for removing layers of paint or other non-metallic coatings from a coated metal hanger or the like comprising the steps of freezing the coating to embrittle it and shrink it toward the metal hanger, heating the metal hanger without heating the coating to expand the metal toward the coating, and stressing the coating by said expanding and shrinking to break and fragment the coating and cause it to fall off the metal hanger.
