Scum & Mineral Deposit Remover, Refill Buddy, 22 fl oz (2 Pack)

I have a granite sink and extremely hard water. This is the best product I have found that removes the white scum left on the sink.I had one bottle that had leaked in transportation. Wasn't to happy with the packaging

I bought this deposit remover to try and salvage my black granite composite sink. I followed the directions exactly, but this remover did nothing to remove the white haze from the sink. I read the package to see if it was safe to use on stainless steel as my refrigerator had some hard water deposits from the ice machine. It did work at removing those deposits as well as some oxidation on the roof rails on my SUV. So, in summary, it does work but not on everything...but then again, what does? :)

Finally found a product where the water stains were removed from our granite composite sink.

Works well but is expensive

I love this item!
