I love to use a product called Evaporust. I have done the electrolysis method too and prefer the ease of Evaporust. You can google it and find all kinds of praise for it. Buy it at an auto parts store. Dave

Just about any DC source will work; the process usually takes just a few amps maximum. I usually use whichever car battery charger comes to hand. I'd strongly recommend using washing soda (sodium carbonate) rather than sodium hydroxide. You'll have body parts fairly close to the process periodically, and while a splash of washing soda is harmless, sodium hydroxide can do serious damage. Newly de-rusted parts can also be protected with a coat of paste wax if they're not to be painted or plated.
