Please help us..My wife and I recently had granite countertops installed in our kitchen. A guest placed the top of the butter dish directly on the granite countertop. I don't know how much time lapsed before I found the dish top, but now there is an imprint of the butter dish on the countertop. My wife and I are just sick! Is there anything we can use to remove this stain? Does this indicate that there was not enough sealer on the stone? Any suggestions would be GREATLY APPRECIATED!
