Electrolysis rust removal

[Frank S]

I've done some Electrolysis rust removal in the past. It is a simple process just need to have a catalyst in the water for conductivity I used common baking soda but Borax washing powder works just as well. For my power supply is just used a small car battery and a 10 amp battery charger. the Anodes are sacrificial and work better if periodically the deposits are scraped off. Use only in well ventilated areas and try not to breathe the gas coming off the solution even through a respirator since the gas will be a mixture of hydrogen-sulfide and sulfur-dioxide and if there is any zinc or galvanized materials in the mix zinc-oxide gas can be deadly.
I never went to the trouble that you did I simply placed a single piece of steel in the bottom of the tub then suspended the part to be cleaned above it. I have had moderate success with reversing the process by using pure copper as the cathodes and the part as the anode, then repeating using a hand full of nickles and a pound of nickle powder mixed in the solution I just needed a better catalyst
