denatured alcohol followed by hot soapy water will remove the flux
your description sounds like the joints were overheated with lots of oxidation - ferric chloride will make quick work of the oxide, as will most commercial copper cleaners.
If you have a digital camers, can you post a pix of a typical joint.
I don't have a digital camera. But I believe you are right in your answer. The plumber in the story who left the flux on the pipe was me five years ago. :-/
