Hi everyone,

First time poster! :)

We are remodeling our kitchen and know we want a black granite sink, but can't decide exactly which one.

We are contemplating a Franke granite or a Blanco siligranit (links below).

Does anyone have any experience/recommendations about the two? One of my main concerns is keeping it clean based on reviews that I have seen.

As a part 2, does anyone have experience or recommendations comparing the blanco silgranit to silgranit II material?
