The parts also seem to re-rust much quicker than raw
steel. *This seems to happen even if you thoroughly rinse and
immediately dry the piece.

Did you use washing soda (sodium carbonate) for electrolyte? Did
it strip paint as well as rust? Did you paint immediately?


Yes, I used washing soda.

The things I derusted were old tools so I didn't paint them. A rusted
solid pair of slip joint pliers that wouldn't budge now work like a
charm. They haven't rerusted because I rinsed them then immediately
wiped them down with a light oil.

An old hand plane that I derusted did start to rust quickly even
though I thoroughly rinsed & dried it then put it on top of the
clothes dryer to warm it up. The top part I painted and that seems to
be holding up pretty well but I'm not subjecting it to 1,000+ temps.

You're going to need a pretty big container to fit a header into, no?
Maybe a plastic trash can.
