I've used a number of different things that have mostly all worked fine. I normally start by scrubbing the board with a fresh bit of green scrubby pad. Rather than muck up a whole pad, I cut off a small rectangle and use that. Once the copper is nice and shiny, I wipe it off with cleaner. Rubbing alcohol and Windex both work well, Naptha and Acetone are also good but much more stinky. The key is to use something that evaporates fully and leaves no residue behind.
Also forget the iron, get a laminator and you will never go back, there is no comparison to how much better it works.
