For those who are fans of the Bar Keepers Friend Classic Cleanser and Polish, this delivers the same results, but in a pre-mixed formula to make for a quicker clean. It works well against rust stains, tarnish, mineral deposits, soap scum, and indoor and outdoor grime, and is especially good on the following surfaces: stainless steel, brass, bronze, copper alloys, aluminum, ceramic, porcelain, glass, corian. Recommended to use in the kitchen (sinks, cookware, stove cooktops and exteriors, oven door windows, non-stone countertops, and plates to buff out knife marks), bathroom (sinks, bathtubs, showers, faucets, toilets, tile, and grout), and outdoors (rust stains, grills, vehicles, siding, and sporting equipment).
Promising review: "I was so bummed when I scratched up my pretty white sink with pots and pans. I thought I'd need to have it replaced or try to sand it and refinish it somehow, but I bought this stuff as a last ditch effort to fix it myself. It takes some elbow grease to make them go away, the scratches don't just wipe off. But if you scrub at them for a few minutes they melt away pretty quickly. After two rounds my sink looks nearly brand new again. It also worked on a few mineral stains in my bathtub that I thought were permanent after soft scrub failed to remove them. Again, a little of this stuff, the scrubby side of a blue sponge, a little bit of effort and they were gone!" —Dan Borden
