Pickled Tun - sour note?

  Just finished making my mash tun (10 gallon Igloo) with a copper manifold.  I remember hearing something about pickling the copper prior to brewing.  How do I go about this?

Its brass you need to worry about.  Or more correctly the Lead in the Brass.
See this link  http://www.howtobrew.com/appendices/appendixB.html
for a discussion on brewing Metallurgy and how to pickle any brass fiitings.

All the best, David

  Thank You!  I did find the 2-1 vinegar - peroxide solution AND the info about copper.  I was pretty sure I did not need to worry about the copper.
