All iPads Polyurethane Smart Cover looks dingy

[qtrim]

I bought the official Apple polyurethane Smart Cover in black. After less than a week it looks dingy. Has anyone found something good to apply to it to make it look better? It looks like a car tire that needs Armorall.

With the iPad 4 and its Smart Case (same material) I just used warm water with soap every month or two. I had the green one.

Armor all has a lot of Silcone in it and I am not sure if it would not degrade the case. Just cause it looks better does not mean it is good for it. I have the black smart case and just a damp cloth about once a month does good for me. I also have the tan smart case on my other Air and damp cloth works wonders.
