I wonder if this laminator is too hot. It sure seems at least as hot as my old clothes iron. The board is very hard to hold onto when passing it a few times through the laminator.
The magazine paper has micro-wrinkles after a couple of passes. I think it may have gotten the paper so hot that it shrank a bit. Just a guess. If it distorted the traces at all, then the next round I'll add another sheet above the magazine paper to see if it will help it not to micro-wrinkle.
The magazine paper moves all of the way through the laminator without being pulled or pushed.
I used Tarnex for cleaning the copper. It does a great job.

Both worked better than acetone since they did not evaporate to fast and stain the copper. The edges of the board are stained, but are also super rough from being sheared. I should try both solvents on a board with no copper.
