From my experience with electrolysis, I found out that the baking soda electrolyte is as effective as the washing soda solution, provides satisfactory results, and harmless - it does not irritate the skin. While mineral acids clean away the outer layer of rust, they also put the underlying metal in a reactive state, making it susceptible to flash rusting unless it is otherwise sealed or neutralized. Rust removal using the science of electrolysis is an inexpensive way to remove rust from large items which otherwise could be a costly process. Making an Electrolysis Machine In electrolysis rust removal, some resultant atoms are liberated as a gas (hydrogen, oxygen), and other resultant atoms are deposited as a solid on the electrodes (black sodium carbonate, rust). Its important to consider safety, disposal of the rust removal solution, time and other factors. In electrochemical terms: Electrolysis is a decomposition of chemical compounds by means of passing a direct electric current (DC) through an electrolyte (a solution of acid, base or salt). It will look really scummy while it's in use but the rust and gunk just settle to the bottom to leave the water clear again. Before you begin with the process, you will need to take some safety precautions. The place of your electrolytic setup should be fairly isolated from human and animal traffic. Electrolysis is a technique for returning surface rust to iron. It's also easier that sandpaper, etc., gets into nooks and crannies, cheaper than paint stripper and environmentally friendly enough to just throw down a drain.There's a bit more about how I use it in my G.I. While it is a good conductor electrolysis of salt water produces concentrated and gaseous Chlorine and Hydrogen.
