Composite Granite Sink Cleaners Care Maintenance Kit, Buddy Pak
The only cleaner I have found for my granite composite sink that actually works! Gets rid of the white discoloration. Makes such a difference in appearance. Will only buy Supreme Surface now.
I think my expectations were too high.....it definitely cleaned the sink well, but the finish and sheen was not returned as I hoped.

The products work very well, exactly as described. However the Customer service sets the bar high for anyone else. I have not received personalized service at this level…possibly ever! Highly recommend!
