I got a Hori Screen Protector. The top one went on great. The bottom one, not so much. You see, the cut was at the tiniest of angles, so that I could line it up with one side and the top corner, but then couldn't get the other top corner on. I took it off and set it (face up) on the table so I could make sure I was doing it right. I then took it and aligned the bottom corner first, and that worked. Except now it's covered in dust. It's not horrible, but it can be seen on dark screens. Anyone know how to get dust off sticky stuff?
