Homebrew PCBs

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.
