After fabricating the components for a Stuart 10V crankshaft, I silver-soldered them into one piece.  The next problem was how to remove the flux before finishing.

I used a vinegar bath, time, and a few gun cleaning brushes.  Many references suggested a weak sulfuric or muriatic acid solution, but the vinegar worked and I could do it at the kitchen sink without wearing protective equipment and then flush the residue down the drain.

Can’t display content.



Worked great!

I use Firefox when making this post, and just learned that my photos don't display with Internet Explorer.  Sorry for the inconvenience.

Another one for citric acid, usually sold as ascorbic acid here in the States.  Best I've found for a pickle that
won't hurt your skin (or your insides, if you get it in your mouth).

Looks like you got good results with the vinegar, too.

They're not the same thing, but will both work.

I have!    

I also use vinegar for rust removal and dunking brass components.

I don't know why I typed citric acid in that sentence when I was thinking of vitamin C.  Consider that
a typo.  One little oxygen atom screws up the whole keyboard...

I also use citric acid for large items and my jewellers pickle for smaller items.
I forget the brand name now but it is faster than citric acid, but safe unlike sulphuric acid
