Hmmmm...... your applicator/strip is turning black when working on this eh? I always just assumed they were clear coated aluminum but then again I've not had to do anything to mine. If they're clear coated you wouldn't be getting the black transfer onto the applicator/strips, but by the same token you should then be able to clean up that staining, regardless what it is.
You may want to try just a plain ol' metal polish like Mother's or Meguiar's with a terry cloth towel. I'll have to take a closer look at my sills when I get home this afternoon.
