Given the type of material BMW commonly uses, a little surface rust here is not unusual. Often acidic wheel cleaners will contribute to this problem so I highly recommend a pH neutral wheel cleaner and take extra time to rinse brake parts well after washing wheels.
Thanks for the reply! Yes, it seems like my cleaner is acidic and probably made this worse.

Do you think I could use light sandpaper to sand the rust off, then perhaps seal the surface with something like Crystal Serum or some other ceramic coating?
