Here's new information on electrolytic paint removal: Submerged copper wires are better than steel wires to connect the graphite anodes to the circuit.

Copper wires from residential Romex cable works well.

The reason is that steel wires will be quickly consumed as part of the sacrificial anode, which means they will fall into the electrolyte in the middle of the night with the attached alligator clip. The result will be a ruined alligator clip that will need to be scrapped and replaced.

Copper wires will plate copper onto your part a little bit, but it won't matter much, because the part isn't clean enough for the copper to stick anyway.

The copper wires will be eventually consumed same as the steel ones. Inspect them daily for replacement before loss of another alligator clip. Need a dozen or more alligator clip ends in reserve.

When I changed from all steel wires to all copper, the current draw went from about 1 amp to almost 2 amps. Two or 3 amps is optimal.
