You can remove the rust and nothing but the rust, no damage to any other metals..no wear or erosion of the base metal..and if the finish is impervious to sodium carbonate no damage to the finish will take place.
Use graphite electrodes not steel.
Very easy set up, and it works like magic. Search "Shop Dog Electrolysis Rust Removal" and be amazed....
Ask if you have any questions on what you need or in general how it works, what prep helps and works better for set up. I've been using this process for years now with good success ..it works better some ways than others.. i have found through trial and error many ways it doesn't work well...
