Just a heads up, this was one of the big causes of the screen coating issues from the earlier rMBPs. Apple specifically warns against any solvents on the screens...lens cleaner is full of solvents to dissolve the oil that people get on glasses. I wore away a small patch of the coating on my old machine using glasses cleaner.

"...don't use aerosol sprays, solvents, abrasives, or cleaners containing hydrogen peroxide that might damage the finish.
To clean the screen on your MacBook, MacBook Pro, or MacBook Air, first shut down the computer and unplug the power adapter. Dampen a soft, lint-free cloth with water only, then use it to clean the computer's screen."
