I just bought these plastic covers that go over the glass, but I had trouble with the first one. First on the semi sticky side I had some dust particles on it. How do you get them off? When I tried wiping it I smudged it and could not for the life of me find anyway to actually clean the surface of the sticky side.
Now I have all kinds of smudges and I think the first one is ruined. So how long does one usually last and if the second one gets dirty on the sticky side, what did I do.
***update***
I put cleaner on it and the film disolved...I think its what makes it cling to the screen
