invisible shield dust

[Sturatt]

I recently ordered two invisible shields from shieldzone.com. I installed one on my titan and one on my brothers. His turned out perfect, but mine somehow got a ton of dust on it. The dust is stuck to the sticky side of the invisibleshield, and i cant seem to get it off. Has anyone had any luck with removing dust from the sticky side of an invisibleshield (or similar screen protector)? so far i have tried water, soap + water, contact solution, the application solution that it came with... nothing seems to get this other side clean.
