My CT w/ 3000 miles has the tan leather interior. I am very fussy about keeping the interior clean right now even though, because of the bad weather here in the midwest, the exterior is filthy! My problem - the center armrest is getting dirty and it won't clean with anything. It might even be that the color is wearing off the surface, but I'm not sure. The leather surface looks a little grey and no leather cleaner or household product(like 409, Awesome, etc.) will clean it. Anyone else experiencing this? I may take it to the dealer when we get to Florida next week and ask for the armrest cover to be replaced. This is crazy. The color should never wear off that quickly!
