Rust is a result of oxidation. Electrolysis starts a so-called redox reaction, which transports the ions from the side of the rusty piece to the galvanic anode. The underlying material including solder material is not attacked.

that's good news I wasn't sure thanks Tom my job of de-rusting the tank just got a bit easier once it's done I'll also run it through with "Fedox" then I'll seal it with Bill Hirsch tank sealer.....I'll post up results when I get around to doing the job......cheers

how would Electrolysis affect the Soldered joints of a Flat tank petrol tank do we know

Hi Thomas
Thanks for this. I have tried the technique and it works very well. I had some cast iron model locomotive wheels that were pretty rusted and I used this technique with good results.

Hi all!

Attached is a description from a fellow BSA afficionado about how to remove tank rust by electrolysis.

Cheers, Thomas
