If you find the dust attracted to your screen protector or find your finger drags on the screen, a car detailing product, (such as Meguiar's Ultimate Quik Detailer), briefly sprayed onto a soft cloth and then rubbed on to the screen, works wonders as a temporary oloephobic and anti-static coating.
Any decent detailing spray will do the job, no affinity with Meguiar's.
