This invention provides a composition and method for maintaining the appearance of stone floor surfaces such as marble that avoids the need for use of oxalic acid. This is provided by a stone floor surface crystallizer composition comprising from about 12 % to 25 % of a silicofluoride crystallizing agent such as magnesium silicofluoride; from about 15 % to 25 % of at least one fatty acid containing from about 16 to 22 carbon atoms such as stearic acid or mixtures of palmitic, stearic and oleic acids; from about 25 % to 45 % of at least one particulate abrasive, more preferably, an aluminum oxide abrasive; from about 80 % to 140 %, based upon the stoichiometric amount of carboxyl groups present in the fatty acid of the composition, of at least one alkaline neutralizing agent for the fatty acid such as a volatile amine such as triethanolamine; from about 0.1 % to 2 %, of a silicone fluid such as polydimethylsiloxane fluid having a viscosity of from about 100 to 2000 centistokes (0.01 to 0.2 square meters per second) at 20 DEG C; and the balance of the composition comprises water. |
