Scotchbrite is a line of abrasive products from 3M. The green colored
pads work well. I got good results by using the green pad and water to
remove the surface layer, then soap + hot water to remove the bulk of
dirt and oils. After drying, I used a clean, lint free wipe and acetone
to make sure the surface was free of oils.
I also found that different irons vary significantly in how hot they
get. One of our irons worked much better than the other.
You may want to check into a laminator instead of an iron.
