Correct pre-cleaning is essential for the successful protection of the glass surface. Only when the glass surface is absolutely clean can BriteGuard® Surface Sealer or BriteGuard® Surface Sealer X combine with the glass to build a protective layer over the entire surface. The glass can be cleaned either manually or with a glass washing machine. BriteGuard® Surface Activator must be used as detergent for smooth glass surfaces at a ratio 1:10 with water. BriteGuard® Surface Activator removes organic as well as inorganic contamination from the glass surface and chemically prepares the glass for the coating.
