Thompson Traders KDU-3120AH Monterosso Double Bowl Hand Hammered Copper Seamless Construction Hammered Medium Antique

I love the look of this sink and especially the color. But no matter how careful I am, someone (including me) will accidentally forget to rinse the sink after use. Dishwashing liquid and hand soap will both remove the patina and leave "shiny new penny" spots. The spots are very noticeable and take forever to repair themselves. We all know not to leave acidic liquids like lemon juice, tomato products, etc. in the sink, but it seems like almost anything will damage the patina.

My father purchased a copper (hand hammered) sink and was extremely happy with the look.I purchased the same, and before installing it, he warned me about the maintenance, scratch prone, delicate nature of the sink. I gladly returned it.
