I found that it helps to be in a little bit of a humid room if possible to keep dust down (like shortly after a shower, in the bathroom). Also, I usually rinse my hands off and dry them loosely, enough to keep water off, but still hopefully enough to be damp enough to discourage static. It's a pain to make sure the screen is clear, since any dust becomes a pain once there. I usually hold my breath as long as possible, wipe the screen with a microfiber while staring at it under light from every angle possible, trying to clear any smudges, and dirt. Lots of times, it takes me a few wiping sessions before I dare try the protector. And even then, I ain't perfect half the time. lol.
