Hi all
I have an issue, about 12 months back i packed all my 1/2" and 1" coppers fittings in a toolbox and put it up on a shelf, MY WIFE thought i would be a good idea to put 2 bottles of flux in the same toolbox laying down. The flux has leaked all over the fittings I have, leaked out the bottom of the toolbox and all over 2 4 foot lengths of 4" copper pipe, the pipe has now a green type colour all down it and the fittings are like mouldy and discoloured.
I have tried a Bi card and vinegar solution on part of the pipe, but the shine of the copper in some parts has faded
What is the best way to clean this mess up
