Haven't seen many posts regarding electrolytic rust removal. Considering rust is something that all of us (at least most of us) have to deal with, I figured I would post up my results!
I recently purchased this turbo manifold from a member on here, and it had the typical amount of rust. It will eventually get ceramic coated when I have a turbo to coat as well, but untill then I figured I would try this out. I followed the instructions found HERE.
Manifold as it arrived...
Worst area of rust...
The bucket and anode...
After sitting for two days, this is the anode, complete with holes...
Anode and Cathode (the manifold) together...
The manifold after about 1 hour of brushing by hand...
The turbo gasket surface. Can still see the line of the old gasket (Might end up doing some porting!)...
All in all, it came out much better than I expected! There is still a bit of rust around the ends of the runners, which was farthest away from the anode. I might just throw it back in for another day with the runners facing the anode this time. Turning the manifold would have given more even results (next time ).
