Electrolytic rust removal

[The Dark Side of Will]

Following Alltrbo's example of electrolytic rust removal on motorcycle parts, my dad and I tired it on the windage tray for the C5 Corvette oil pan going onto his 5.3 that's going into a Datsun 260Z.
Alltrbo's info: http://www.750turbo.com/forum/viewtopic ... ectrolysis (setup description near the bottom)

The solution is one teaspoon of washing soda (*NOT* baking soda) per gallon of water.

EDIT: Using a 12V *MANUAL* battery charger. The automatic battery chargers won't work because they think it's a dead battery and shut off.
Positive terminal on the sacrificial anode (cathode?), negative terminal on the part being cleaned:
You can see bubbles starting to come up in this picture.
The current got up to about 5 amps accoding to the dial on the battery charger.

What looks like turbidity in the water is turbidity in the water caused by the flow of bubbles of hydrogen gas from the parts.

Also noticed that Mach10 has a thread on eletrolytic rust removal: phpBB/viewtopic.php?f=3&t=6984

He mentions finding a page in which it's used on old Lotus parts

Also again, recent successes with electrolysis:

From this:

The pinion isn't in bad condition except for the teeth
