Reissue Sixshot Chrome parts scuffed/stained fight out of box?

I recently recieved a reissue sixshot from an ebay auction I won.
But the shiny parts of the wheels have a scuffed stained look to them, and no matter how much I scrub them they look the same.
Any experience in this? Is the stain baked in with the chrome part of the plastic?
I have opened a paypal dispute on the seller since clearly the item was not opened only for inspection but if I can fix it that would save me alot of hassle.
