Color Intensifier & Shine Enhancer for Quartz Countertops Lustro Italiano Quartz Stone Polish & Enhancer is a food-safe liquid polish engineered to deepen the natural color of quartz surfaces and enhance their shine. Unlike a standard cleaner, this product penetrates the surface to intensify color and improve protection against water- and oil-based substances — making the surface easier to maintain and more resistant to everyday staining. Works on all quartz finishes: polished, honed, sandblasted, flamed, rough, and brushed. 8.5 oz liquid. Coverage: approximately 254–407 sq ft per quart. Note: This product does not provide anti-etch protection on natural stone. For etch removal on marble or limestone, use Lustro Italiano Etch & Water Mark Remover Powder.
