I think this belongs in Vent here. There is nothing worse than installing a screen protector. Just when you think you get it right you will notice a small speck or fingerprint. But @C Pav had good advice, take a long hot shower, then why the room is somewhat steamy install it. The dust particles in the air get pulled down by the water molecules in the air. Way less of a chance. Also be patient, it takes a good 24-48 hours for it to look better. It can look like crap for awhile until the small amount of glue dries. When your doing installing them you feel the pressure of diffusing a bomb.
