Hello, Our goal at Sinkology is to make sure that our customers are very happy, by offering them great quality products, and by honoring our promises. We also believe that the beauty of copper is his natural patina, therefore we do not add coatings to our copper sinks and the Copper Armor was designed to keep the sink beautiful and shiny while helping to avoid water spotting. It is recommended, but it is not necessary and we recommend to apply it once or twice a month. We also stand behind our products with a lifetime warranty. Our sinks are very easy to maintain and all it needs is to be washed with water and regular dish soap and it is a pleasure to read that you love our sinks. Please don't hesitate to reach us out at firstname.lastname@example.org if you have additional questions or concerns. we are happy to help. Thanks!
As far as I know, it always comes in a kit, which actually makes sense. This way, with each new kit, you are receiving a new scrubber and rag, which reduce the odds of an embedded object from the previous kit accidentally scratching the soft copper.
I use SInkology, pkg includes 16 oz. Wax, 2 microfiber cloths and Breeze non-scratch scrubber, the entire package is known as the "Deluxe Copper Armor Care Kit". I use it on our copper sink and it helps preserve a uniform patina that will naturally age and darken over time and use. Hope this may have been of some help to you.
