Mira Soap. Specialty No-Rinse Maintenance Cleaner. Mira Soap is a specially formulated no rinse stone soap designed for easy ongoing maintenance of honed, tumbled, textured limestone, marble, travertine, terrazzo and other stone containing calcium. Mira Soap produces a protective film that protects the surface of the stone. Mira Soap only reacts with the calcium in the stone so there is no risk of buildup like a traditional floor coating. Non-textured surfaces can be buffed with a floor machine and white nylon pad for added patina or shine.
