Whether the sink is raw copper that will develop a natural patina, pre-treated copper with a developed patina, or shiny lacquered copper, the care is simple if you stay away from harmful cleaners.
How Often to Clean a Copper Sink
Just as any kitchen or bathroom sink that is used daily, a copper sink should be cleaned daily. If you live in an area with hard water, the minerals in the water will leave water spots on the surface of the sink. To prevent the spotting, dry the sink completely after every use. If you have a shiny lacquered copper sink and want to maintain the look, the lacquer will eventually be worn away. The sink will need to be relacquered or polished with a copper cleaner and waxed with carnauba wax or specialized copper wax regularly. The frequency for the need to wax depends upon how often the sink is used.
How to Clean a Copper Sink

How to Maintain a Bright Copper Finish
If you have chosen to have a bright copper finish for your sink instead of allowing the natural patina to blossom over time, you will need to clean and wax the sink regularly to maintain the shine. Raw copper will begin to turn dark very quickly. Think about how quickly a new copper penny begins to darken. If you want a shiny copper sink, choose a lacquered finish from the manufacturer. Even with careful cleaning, the lacquer will eventually begin to wear away. When you notice the copper beginning to darken or discolor, use a polish specified for copper to clean the sink. When the shine has returned, coat the sink with Carnauba wax or a specialized copper wax and buff to the original shine. This should be done at least every six weeks. You can also have a metal expert reapply a lacquer onto the copper.
