I use a scotch tape to lift up and dirt or lint when applying screen protector.
Not after you've already installed it and see it after the fact. There's no way to take it off and keep it adhesive.My brother and I run a ZAGG store at a local mall, and this is exactly what we do to remove lint or anything else that sneaks under the glass shield during installation. Scotch tape does an excellent job lifting stuff off of the adhesive side.
