There is already a tech tip on this. I guess the "washing soda" had me bamboozled it's just common baking soda. The stainless electrode was just some scrap I kept tripping over but was unwilling to toss. I was being conservative using the smallest charger I had 1.5 amps since I had never tried it. It's so dam easy, you will be amazed. You don't have to sit there and watch it, just hook up come back in 2-3 hours. I usually pull relic then and scrape surface rust off, rinse and go a little longer if it needs it.
The only thing is when you are done, rinse, clean and wipe dry. Keep it dry. Then before painting, I think you need to wash wipe down with something like zero-rust Prep step which would give you the best PH for the paint to adhere to. More amps may make this go faster, I don't know. You can probably set this up in about ten minutes if you have the stuff. You may be able to use copper pipe for the electrode too. Once I'm done with the hubs (cleaning for disc brakes) I will move on to stuff like battery box covers, hold downs, small stuff. When I get a bigger setup I will use this on wheel rims and brake backing plates etc.. Once you try this you will ask why you never did!
