How do I polish a nickel plated hammered copper sink?

by Bobbie
I ordered this huge, (3-bowl, 43" wide), farmhouse kitchen sink. It was supposed to be polished nickel over copper, but it was not polished and is quite ugly. I could not return it since it would cost quite a bit to send it back to Mexico, around $1700. So I bought another sink for for my 2012 new kitchen. I did try and was unable to sell this copper/nickel sink on Craig's List for less than half its price, which was around $3500. I was definitely "taken" by a company called "Rustica"! Even the nickel plating was not a good job, chipped in some areas and the slight tinge of copper showing through in other areas. Now we have bought a rustic vacation cabin in Maine and thought we would install it there. But I would like to try to hand polish it myself. But I don't know how it's done. does anyone know?

    I want to add sheen to the nickel plating on this hammered copper sink. Now, it's a dull matte battleship gray. I want a shiny polished nickel finish that I know is achieved by hand. But how? What material do I use?

    Plated nickel is more like silver plate—it will gradually develop a patina over time. Most common metal cleaners can be used to brighten the nickel finish periodically, but use them carefully. The nickel plating is only a thin layer covering copper. Overzealous rubbing can remove some of the nickel, allowing the copper color to show through. NEVER USE anything abrasive. Also, if the copper portions of your sink have a patina, keep the metal cleaner away from the copper. I recommend cleaning with mild soap/water, polish with Flitz, then use Renaissance Wax or carnuaba wax on these sinks to avoid metal cleaner mishaps. Most people hate these sinks due to having to clean them practically every week.

    Sounds like William has had some experience in this department . I always defer to the one with the hands on approach!

      @MN Mom I've installed quite a few of these and taken a few out. I try to explain to clients about the pros and cons (more cons) of these, but I give them what they want. These aren't cheap $1,000 and up, but the quality isn't there.
