Want to clean the inside hub of mag wheels

[Bob]

I have a 01 S40 and the inside of the mags (where they
connect with the disc housing) is covered in a whitish
powder, similiar to corrosion.
What do people use to clean it off and protect the mags as
well as helping to keep them from sticking to the wheel hub?
All ideas are welcome.

To keep them from sticking to the wheel hub I use Copperpaste (comes in
tubes and boxes)
