Review on 💧 1 Quart Stone Pro Hard Water Deposit Remover for Stone and Glass Scrub by Darin Marshall

This polish works well for removing water deposits from a black granite shower stall with a smooth finish. I use a Makita variable speed polisher, which is much faster and less painful than hand buffing. I don't think hand polishing will give the same results as a mirror clean tile. The only downside to this polish is its slightly creamy color, which ruins my black grout. Grout takes longer to clean than tile because everything needs to be hand brushed with a small, narrow brush. It is very difficult to get out of the grout and even after cleaning I can still see the difference between the original grout lines and the polished areas. I would like this polish to be black or dark grey. I would buy a suitcase if there was one.
