Promising review: "This stuff is like magic! Straight up wizardry. I love it! I initially bought it to clean my sink, which is porcelain, and even though it's not even a year old, is just holding on to all the coffee and tea staining. I'd say it took less than a minute after making a paste with Bar Keepers Friend to clean the sink up to a nearly new shine. Taking a look at the can, it's easy to find bunches of ways to use this stuff and each application is better than the last. Stainless steel, porcelain, ceramic, copper, brass, fiberglass, corian, chrome, and aluminum. See? Magic! Anyhow, I've used it in the sink, in the bathroom, to clean stainless steel pots and pans, on a 17-year-old Revereware tea kettle, (which I thought would never be restored to its former loveliness, BTW). This is a product that I will buy again and again, and will happily recommend to anyone." —Nicci Stephenson
