Thread: the effect of Electrolytic de-rusting on Soldered joints

Lead, which will be the main constituent of the solder willl be pretty unreactive. Electrolytic cleaning will be fine.

thanks Tom I did suspect that but I wasn't sure......cheers

thanks Tim.....I'll keep asking around on the interweb someone somewhere has restored one of these tanks somewhere......cheers

This is something I'd experiment with. It depends partly on the electrolyte, which I assume would be Washing Soda. In theory, I'd expect Tim's answer to be correct - the action would mainly effect the rust rather than a Lead/Tin mix. But electrolysis is a powerful way of ripping molecules apart, so I'd want to double check by trying it on a victim.

Why not solder some tin-plate together (old cans), rust them up by scratching and wetting with salt water, and then electrolytically clean them. I'm 80% confident electrolysis won't damage the soldered joints, but I wouldn't risk doing it to a treasured tank unless I'd gone the extra mile and made certain!

to be honest I am going to solder up a box of tin plate with soft solder get it rusty and see what happens like you say Dave it shouldn't do anything to the Solder but you just never know.....cheers Dave

thanks for the replies chaps......the elctrolyte solution I would use is basically washing soda (Sodium Carbonate) mixed with hot water that's all nothing corrosive as far as I understand I'm just wondering as the solution attracts and lifts the rust would it do the same to any lead in the soft solder.....agh......such an easy thing to do but is it on a soldered tank.....using a proprietary de-rustng solution might be worse

Hi All

I'm a newbie here and I have what may appear to be a simple question but I haven't managed to find any kind of answer so far so here's my issue......so I'm restoring a 1927 Sunbeam model 9 motorcycle not a scale model but the real thing.....the combined petrol / oil tank of Flat tank design is of original of soft Soldered Tinplate construction unfortunately it is very rusty inside so I'm hoping I can de-rust it using Electrolysis.....but before I start doing this I really need to know if this will dissolve / erode the Soldered joints can anyone he me out
