Ron, the plating on the grills is the only thing I don't like about the CS.. It is NOT stainless and it is NOT chrome according to Tony, or whoever the guy was that I talked to. I'm sure it is simply a cost issue with CS.
Scotch brite is quite abrasive.. they use large scotch brites to strip floors on buffing machines. Take a piece of chrome.. like a bumper and I think you would see scratches on it after rubbing with the green scotchbrite... and chrome is quite a bit harder than what is on the grills.
That said, I'm down to copper and steel in some places on my grills. It doesn't affect the cooking. In fact, I doubt any of the log burners
have anything but steel/iron grills.. they get a good coating of whatever and just keep on cooking.
Don't worry about it.. it'll cook just fine. Enjoy the product you turn out.
