DOn't know about granite sinks but I went with a soapstone sink in white no less. I've changed out sinks twice in this house but kept the 1st soapstone sink and moved it to my basement kitchenette cause I love it so much. True white sinks get stained but with soapstone I can use just about anything to clean it with no problems. I can during the Fall time so you know it's going to get stained from tomatoes, berries, etc so I wait till I'm done with canning and then I spray a mixture of bleach and water on to the sink, walk away and do something else and then come back anywhere between 5 and 30 minutes later and finish scrubbing it. Love my soapstone sink.
