Review on Granite, Quartz, and Marble Cleaner Polish with ioSeal Protectants - Supreme Surface by Tony Beale

I gave 4 stars because the label is misleading. It's not a cleaner - it's a polisher/sealant. I purchased this product for my black quartz composite kitchen sink which was stained orange-brown due to the incredibly hard water we have here in Arizona. This product does not "clean". I have tried several descaling products including Lime, CLR and this product. Nothing worked. Then I used Mr. Clean Magic and as if by magic the sink is clean! Once the sink was clean I used this product again and it made it shine and look new again. I've noticed that after polishing with this product, the water seems to collect in drops, preventing it from settling back onto the sink. I would recommend this product but only if you clean your sink first! If you don't, this product will not help you.
