For rust removal, I can confirm that electrolysis works well. Use "washing soda" instead of baking soda if you can, and use the cheapest brand available without much other stuff in it. I think Sodium Carbonate is what you want, and baking soda is sodium bicarbonate, or maybe I have that backwards. A 6 Amp Schumacher manual (not automatic) charger works well as the power supply, as does an ATX computer power supply. Use any scrap steel for the electrodes, and I recommend more than one electrode.
