Removal of inorganic coatings from glass substrates

Abstract:

Methods of etching an inorganic layer on a glass substrate are described, the methods comprising contacting the glass substrate including an inorganic layer with an etching solution comprising a polar organic solvent and an etchant, wherein the inorganic layer is removed at an inorganic layer etching rate and the glass substrate is etched as a glass etching rate.
