I've used Electrolysis in the past and just started using it again. I'm using similar equipment, an old PC power supply running on 12v @ 10amp .. though am thinking of wiring up the 5v @ 30amp wires to see if it gets any better.
unfortunately my sacrificial anode seemed to have dissolved away lol .. quite surprised when I pulled it out.. seemed like acid attacked it.

as you can see.. the missing section isnt suppose to be missing :P .. might have to get myself something a little more solid.
One other thing I noticed, the last piece I cleaned up with electrolysis, I hosed off and left to dry, only to come back to find surface rust.. any ideas how to prevent that from happening ?
