Anyone else experience this? On top of the door, almost symmetrically on each side, the gloss finish has faded. It is not dirt or ash, I tried to clean it. Seems like the enamel finish has just lost it's luster. I am trying not to get too upset about it, it is a stove and it will get banged up over the years. But it is only a year old, and I did pay extra for the enamel finish. Maybe I should contact dealer?
