I have been wanting to give it a go for years and have never got around to doing it.
Does the negative or positive go to the part? Does a higher amp charger work faster? I was told to use washing soda and a scrap piece of stainless steel as it lasts longer. I have a caustic soda wheelie bin for paint removal and a molases bin for rust but it is too slow. Jeff

rust removal
Jeff
The Negative lead goes to the rusty part ... Positive lead connects to a small piece of steel , can be stainless or galv. anything really . I've found as little as 4 Amps works fine .. it depends on how big the part is and how close the electrodes are to each other .. Closer electrodes = higher Amps . Ideally, you want to surround the rusty part with the POS electrode ,this isn't easy to do in practice . Watch the charger ... check it often to see it isn't overheating . If its pulling too much current , just move the Pos electrode away slightly . After removing the part , wash it down with clean water and brush off the residue . I give the part a quick coat of that diluted phosphoric acid solution , before the air has time to recoat it with rust. Mike
