Like the usefulness and quickness of Superox 100-T cerium, but don't like the orange mess it makes? 513EX White cerium is for you. On equal, if not greater ground with Superox 100-T for hand polishing of glass, this cerium is a pure white compound that causes minimal staining and mess but with high yield results. We love this stuff. No more pressure washing all our clothes after a day of polishing.
