Sounds like the old MLU posting on removing rust.......
....with a lye solution, in a plastic barrel, using DC current to remove rust, grease, paint and skin if your are not serious. We used a large battery charger and a bank of old 12 v batteries...... it really bubbles off with hydrogen gas so you need a sunny day outside. I used a circular SS plate wrapped to the inside of the barrel. I did both axle housings, one half at a time suspending the axle castings from the tractor bucket....high pressure spray wash/rinse......metal prep ( phosphoric acid ) then POR 15 all in one warm sunny afternoon.
Mike is right you can by the solution in 40 pounds bags in agriculture/feed store a lot cheaper.
If you notice that the skin of your hands are getting slippery, it's your skin fat dissolving in lye......... a very quick rinse in water will resolve the solution.
Goggles.... good thick rubber gloves and old clothes you plan to junk is best.
Dispose of the barrel content one a heavy rainy day.....keeps the weeds away for the rest of the season.
