Hello Enthusiasts!

I stored a dozen cylinder movements (50- and 72-teeth Reuge movements) in
a wrong place -- it was too moist.  Two years ago I brushed them with a
little bit of clock-oil (not much), and I thought, "That does it against
rust," but it seems to be false.

Meanwhile around the pins on the brass cylinder there are brown-black
rusty spots (shadows).  What's the best treatment to destroy the spots?
Many thanks for response.
