How do I keep an old sink looking clean?
I have a dark black/grey kitchen sink and is made from some sort of granite/Corian material. It looks terrible all the time. Do you have any cleaning tips? Or could I paint it? If so, how? I've tried many products, but always looks dingy and dirty.

A kitchen sink is just about the most brutal environment in a house.  Just think of how much abuse these areas take.  I would be very concerned about any paint or coating holding up here.  I hate to say it but you might want to look at replacing it with a porcelain or stainless steel sink.  By the time you painted it with a epoxy (about the only thing that might work) you could have pulled it and replaced the sink.
