Default Test Results was Salt and vinegar for rust removal

Check your inorganic chemistry books under electronegativity. Sodium's
about as good as it gets, iron and copper not in the same league.


Although iron and copper straddle hydrogen, which is an important
watershed.
Very few sodium tools available

Of
course it helps to have a good acid electrolyte in your cell.


That would be acetic acid?
H+ is surely what you need to dissolve insoluble
carbonates/hydroxides/oxides?
(Along with an anion that does not have insoluble salts with the iron)

Now try cleaning your silver with baking soda in an aluminum pan....


BBbbbbut the topic was rust

First of all let me say that my interest in this thread, started by Sandy,
was caused by my own questioning of why salt helped clean copper pots with
vinegar.
