I use Electro-passivation.
I apply the citrisurf with a wand that is connected to one side of a 36
volt DC power source.

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)

The wand is a 7 inch long piece of 1/4" copper tube.

To use you dip the scotchbrite pad into the citrisurf solution and
scrub the weld area with the piece grounded.

Elegant simplicity. Thanks.
