Use some clear tape to gently remove dust and hair from game pad and back of protector. The only foolproof way to do it Is to peel just the end off the originally backing (when it's new ) line that up with the edge and pull away the backing as you stick it to the screen. Since you already used both I'd say try the tape method if that absolutely doesn't work you can always wash it, immediately put it between paper towel (not a fluffy kind, the rougher kind so no fuzz comes off on the protector) and once it drys reapply. I've got it to work on my cell phone after washing but it wasn't perfect.
