Have you tried the Electrolytic method of de-rusting?

Yes, I have. I prefer acid: it's much faster; electrolytic leaves a
really awful gunky residue; the length of the current path affects the
derusting.


I also prefer acid.

Also, does it dissolve the un-rusted metal too?

Yes, it does, but very slowly compared to dissolving rust. Just do not
forget to take the piece out in time.

I tried both methods (electrolytic and acid). For smaller pieces,
acid is much more straightforward. Wear eye protection etc.
