There's nothing you can do to get flux out of the lock seam or a lap seam for that matter. Apply carefully, wipe away excess, and flush the surface when finished.
There are quite a few substances that will cut the flux on the surface: baking soda and water, wd-40, and dish soap, in a pinch. You can grain the copper with scotch brite after to get a nice even matte finish

I've read about being certain to clean off flux after soldering. What is the best way to apply flux to a new or repaired flat-lock seam so remaining flux (inside the seam) is not a problem?
Also, I've been entertaining patching some nail holes that were placed in the valleys of a galvanized roof section. Can I just fill the holes with solder, or should I really use a small patch panel (i.e., 1" x 1"). What should I do to prevent flux from going through the hole?
Thanks - Chris
