UltraCare Abrasive Surface Cleaner is a powerful, abrasive cleaner that is safe for use on a variety of ceramic, porcelain and natural-stone surfaces. This water-based, biodegradeable formula is nontoxic and nonflammable, containing no VOCs or acids. Cleaning does not require letting the product stand on the surface. UltraCare Abrasive Surface Cleaner penetrates deep into dense surface pores and easily removes ground-in dirt, grime, rust stains and mineral deposits. This product is formulated to remove most factory-applied waxes and floor finishes as well as light cementitious and epoxy grout residue.  It is excellent for use on heavily textured and hard-to-clean surfaces. Plus, it can be used in combination with any UltraCare cleaner or problem-solver.
