You can use acid (diluted) instead of baking soda as the solution. My understanding (and correct me if I'm wrong) is that plating the metal is reverse polarity of what we see in this thread. So instead of having the positive on the anode and the negative on whatever you're trying to get the rust off, the negative is the anode and the positive is the part/whatever you're trying to plate. Basically the metals migrate from one to the other.
See what you're doing is creating a continuous circuit with electricity, and you're solution is forming that circuit. You could form a circuit in anything, a bucket, a rubber maid tub, whatever's laying around. Baking soda is just less caustic than acid from my understanding, and will not remove chrome or harder metals, just oxidation.
What I'm going to do using this info is try out a parts bath out of a 5 gal. bucket. I'm just trying to remove rust off chrome forks, I'll dip one end in, watch it and wait, then dip the other in without taking it apart. I'll tie all the other parts I'm doing to a chain.
Now I haven't tried any of this that I'm talking about, but plan on it in the next couple weeks. I've been hemming and hawing over what to do with the Indian tank for a while. I was thinking about doing this method to it, but now I'm just going to take it to get dipped at a radiator shop then tigged, turns out it's all held together with JB weld and shit.
