Electrolytic Derusting, Baking Soda or Washing Soda?

It works, 'cos I done it. What I do not understand how is the de-rusting
process different in that it dissolves the iron oxides preferrentially. Is
the underlying iron spared? I would have thought that the process is not
dissimilar from the above and there will be some dissolution of the
non-rusted iron but my chemistry does not stretch that far.

I STR reading somewhere that the red oxides get converted to black
oxides - my experience has been
that most of the black stuff just rinses off and a couple swipes with
a wire brush takes the rest of it off.
