Bad stain on chrome rims??? Any help??

[Racie]

I bought a used set of Foose Nitrous II's. The guy said one had a stain on the center of the wheel but he didn't know what it was and if it would come out. I got a hell of a deal but it looks like it is a brake fluid stain (which he probably knew) if it was just on the center only I was going to get the centers powder coated. He didn't say the wheel had it on the lip also. Is there something that might polish the stain out or should I just get it re-chromed? If it cost just as much to get it re-chromed I will just buy another one and keep it for a spare. Any help would be appreciated...
