I use Electro-passivation.
I apply the citrisurf with a wand that is connected to one side of a 36
volt DC power source.
The other side is grounded to the piece.
The paste carries the electrical current which catalizes the citric
acid.
It is extremely fast and very non-toxic.

Can you describe the wand? Is it just a metal rod or does it have a
conductive (carbon?) brush? (I mean brush in the paint, rather than DC
motor, sense)

I was going to guess a sponge on a pair of jumper cables (like
the fun they had with Gibson in "Lethal Weapon") but Ernie got
a bit fancier.

(Thanks for the info, Ernie.)
