YES! Verdigris will add metallic flavors to your brew. I use Brasso and follow up with vinegar.

then use a high concentrate of vinegar. the aCID will take tarnish off copper, if you have green tarnish that's verdigris and it needs scrubbing

From what i have read, you may still want to condition your new copper with strong vinegar for 5-10 minutes to clean the surfaces and etch any free metals (e.g. lead) from it. same for brass fittings.

i however just soaked in StarSan for 20 minutes the first time, and everything has seemed to be okay. i'm finding all of this information out about 5 weeks too late

i got my StarSan in large bottle from NorthernBrewer, our LHBS carries a pretty small size at a higher price.

white vinegar 50/50 with the hottest water your tap can provide. soak copper for about 5 minutes or until it is visibly clean. rinse good with cool water and dry it as best you can right away to keep it from tarnishing again.

Use Bar Keeper's Friend. Works great! Don't use brasso, unless you clean it REAL well afterward. It's got petroleum distillates, and all sorts of nasty stuff in it. Just smell it!

Verdigris is also toxic. but more importantly, it will give metallic flavors to your beer, so you need to clean it off of your copper.
