OT: Ferric Chloride



Hi,

Sorry for this OT question. A while ago I remeber reading about revitalising
Ferric Chloride, I think the method was by electrolysis, but I cannot find
where I read it. I've searched the web with no luck.

Can anyone help please, I would much better to be able to 'save' this
etchant rather than trying to dispose of it safely.......

Thanks in advance,

John
