I know the topic of how to get VG film off glass surfaces has been well explored in past threads. But I just "discovered " by rinsing my reading glasses off in plain tap water and a good wipe dry with a paper towel that water will clean it. I'm gonna do that to my car if I ever get out of the house long enough to do something useful. I've tried various glass cleaners and they never seem to get it all. But water did on my glasses so...just a thought..
