I got this sink in black anthracite. When it came out of the box, and especially after installing it, it was discolored from grout and other stuff. I was worried sick that it wouldn't look nice, especially when soap and water failed to make it a nice black again. But after checking a small test area, I rubbed a little WD-40 onto it with a paper towel, and voila, it looked like new and has stayed looking new for weeks. I've hardly ever had to clean this sink, unlike the old porcelain sink it replaced, which had to be cleaned almost daily with Bon Ami. It is beautiful looking and requires very little care. What more can you ask for?
