Maybe a few gallons of EvapoRust, or citric acid (available in powder on amazon) in a 5 gallon pail will work jyst as good without as much doinking around.

Paramagnetism reminds me of the properties of semiconductors in transistors; they don't conduct without the control of the base-emitter current.
To me though, the bottom line in this discussion is regarding the chemical integrity of paramagnetic (and ferrous) metals when exposed to acids or alkalines of greater values on either side of the PH scale.
My query here though is if this washing soda electrolytic process amplifies the dangerous effects on certain of these 'nonferrous' metals.
As in, certain metals are made 'edge brittle' by exposure to certain solutions in the electrolysis process. Maybe it could be called hydrogen 'bite' or something.
One thing for sure, I will be extra careful in keeping a cautious working distance in the case of my aluminum, copper, brass, and bronze parts from chemical and electrolytic relationships.
For now I am going to limit my electrolysis tank to ferrous magnetic irons and steels.
Will the conrods be safe in there? I am going to pull the crank assemble apart and treat them individually so I can monitor things easier.
Again, if the situation gets too sticky I would rather get the job done by using the directions on a bottle than spending all my time on rust and corrosion removal science when indeed my main interest is getting the motor rebuilt🦥 in a timely fashion... my time stores are dwindling😃 I want to go for a ride before I pass on.

Personally, I would only use the electrolysis de-rusting on ferrous parts that are external to the motor. I wouldn't do the rods. In fact if the rod were rusted bad enough that they need serious rust removal, I'd replace them. Doing the rods, you'll have to drive out the upper rod bushing and lower end races. I'd think that if the rust is light, a wire brush and mild abrasives would be better.

I have used this process to clean old cast iron frying pans etc. I actually used my welding machine for the power source. Look at some forums for cast iron stuff there is a good bit of info out there. Don't know about other metals, my impression was it mainly was beneficial for removing rust.
