Some serious thought should go into choosing a particular piece of decor or installation, where and how it's going to be used, and what it's going to take to care for something and keep it looking good. This is the first I have heard of a granite sink. That's right up there with using marble in showers and brushed stainless steel cooktops.
I know I wouldn't use Soft Scrub, CLR/Limeaway, acids or other abrasives on a stone surface without double checking thoroughly that it was chemically appropriate and suitable for use on that particular type of surface. If there is a haze that won't go away, you may want to consult with someone who restores stone first to execute a proper plan of attack.
