ProGlass glass polish, in liquid or powder form, is a high-quality grinding and polishing agent for the surface treatment of real glass panes. The ingredients used are also successfully used by the glass industry to remove scratches and polish glass surfaces, and we recommend using a polishing machine to remove scratches. Fine scratches, transportation marks, suction cup marks, coatings or stubborn dirt can also be polished out by hand. A clean cotton cloth, lint-free cleaning paper, a polishing cloth for paintwork or similar is suitable for this purpose.
