"Stained" Wheels

[Juanted]

So, on all four of my wheels, I have "stains": They (the stains) look like dirt or grime, except they do not come off. It seems as though they are "embedded" in the wheels. I have tried washing them with regular (zaino) car wash and a scrubber (the green plastic one -- I don't want to scratch the rims); I took it to the local car wash and use that pressure-washer thingy; I had some "wheel wash" cleaner that I tried. Nothing has worked. It does not appear to be "surface dirt," but rather... IN the body of the rim.

Back in June or July, when I had the X in for service, I had them repair some curb rash that I had in all four wheels. My understanding is that they fill any gaps with melted allloy ( ), file it, and mold it into the wheel... (or something like that... paging Rob_?). My questions:

- Could that repair be what is getting "stained"?
- Is there a way to get this crap off? If so, how? Any suggestions?
- Why didn't the Paige twins (Allison and Andrea) ever give me the time of day when I was in high school?
- When will my suffering over the New York Jets end?

I only ask that you answer 50% of the questions posted above, please.
