For glue ups I have cleaned the lams with Acetone, denatured alcohol, a small scrub brush, whisk broom, dust collector, or air nozzle. I have read of people using all of these methods with success, so I tried them all. They all work. My favorite to use is denatured alcohol, it evaporates quickly and doesn't over power you with the smell. It's the last thing I do after laying them out ready fit the glue. I am always confident the oils, tape residue, fiber prints, and dust is are gone.
