Cleaning Calipers?

["Alexander van Gerbig" <Audi_80@email.msn.com>]

    I have been cleaning my used set of G60's for some hours now and have
gotten a good distance, but it has come to the point where my brass brush,
steel wool, and brake cleaner/WD40 can do anything more.  What can I do to
get these cleaner that I can do myself?  Little rusty speckles in the pits
of the caliper that I can't ride them of.  I actually slopped some rock
miracle paint stripper on the carrier which which has no rubber bits
attached to it and it helped a bit, but not much.  That stuff is STRONG!
Any BTDT for cleaning brakes for painting?

Thanks!
