I still use electrolysis for sensitive things (plane body, saw blade) but have
started using a 50-50 mix of white vinegar and water with great results. Faster,
cleaner, safer.

And I swear the "black stuff" comes off easier after electrolysis if I put some
of the 50-50 on the scub pad. I just make sure to blow dry with my heat gun as I
go.
