@notsure Thanks for the suggestion, but I'm always afraid of chemicals on wire coatings and electronics, I used muriatic acid on rusted gas tanks though.
With that amount of rust I would think the coating is already gone. Muriatic acid is the first that came to mind for copper corrosion but removing iron rust from the magnets could be as simple as white vinegar.
Either way, it looks like a new coating is in order. If you just scrape it off, it'll come back.
Edit: I just saw you did reseal it lol. My bad.
