It protects your stone surfaces from water stains and household spills. The "Spray Any Way" valve allows easy application, even with can upside down. Hi-GLOSS is three products in one. It's a stone surface cleaner, polish, and protectant. It works just as well on engineered stone countertops. There is no buildup with Hi-GLOSS so you can use it without fear of creating a heavy film.
