Abstract
A stable, crystallizing solution of magnesium silicofluoride and oxalic acid is disclosed which can be incorporated into a complete maintenance system covering daily and weekly maintenance along with the periodic maintenance process of crystallization for preserving the appearance of polished marble flooring, terrazzo limestone, etc. The results which can be achieved through the use of this system are determined via an initial pretest with performance quantified using a glossmeter. Final performance results, the visible results of crystallization, are quantified via the glossmeter.
