"Black Beauty" Granite countertop and granite sink

Someone please help!

I recently had "Black Beauty" polished granite countertops installed in my kitchen along with a Blanco Silgranit sink (95% granite 5% acrylic polymer).

What products and frequency of use do you recommend for cleaning the granite countertop?  I was considering the following:

MB-5 QT    Marble, Granite & More Spray Cleaner

MB-4 QT    Stone & More Impregnating Sealer

Should I also use the  MB-13 QT  Stone Polish?  If yes, how often or under what conditions?

Please confirm or recommend additional or different products.  Also, approximately how many square feet will 1 quart cover?

Lastly, something strange happened with the Blanco Silgranit sink.  The granite fabricator polished the granite countertop seam (which occurs at the sink) and the polish water (and whatever polishing additive he was using) ran down into the sink.  The sink now has lightly etched stains in a pattern consistent with the polish water running down into the sink.  I tried cleaning it several times with several different cleaners and scotchbrite and nothing seems to help even a little (nor does it get any worse either). These Silgranit sinks are manufactured to have a matte finish, but now the finish is even more dull and lackluster to the point that I am no longer pleased with the aesthetics.  The fabricator (who also installed the sink) had no ideas.  I called Blanco and they said to clean it with Barkeepers friend and coat it with mineral oil or olive oil.  I cleaned it and coated it with olive oil but the "run marks" are still visible although the oil did give the aesthetics of the sink a boost.  However, when the oil coating goes away in a few days it looks the same as before.  Would mineral oil be any better than olive oil? Obviously, I cannot be the first one to encounter this problem.  I would appreciate any ideas that you may have to rectify this situation.

Thanks in advance,

Scott
