Review on EarthStone International 110SS006 KitchenStone - Single, Multicolour: Enhancing SEO-Friendly Product Name by Cindy Lloyd

This product works exactly as described. I've been trying to remove some blue copper stains from the sink and toilet for over a year with no success. After a few minutes of wet cleaning, they became bright white again. Porcelain will not be damaged at all. The product slowly degrades with use and takes the shape of the surface you are working with. It's just fantastic, and even better, chemical-free! I recommend this remedy to any family with well water to get rid of scale. The unsuccessful methods I've tried so far have been: bleach, magic eraser, bartender's friend, mild scrub, and baking soda. All had no noticeable difference. This product blew them all away! Buy more now.
