Clay, I would expect it to fog the print and paper as it is no longer
ferric, but mostly ferrous. Besides the load of ferrous ions, some ferric,
there will be palladium, paper fiber, etc.  You should filter your bottle to
remove the solids and add some fresh. You may also have a build up of a non
soluble iron compound. Much of what is left in your paper, is determined by
how you coat and expose it. Clean edges will give you more than if you
exposed the brush strokes.
