iPod Touch Invisible Shield

Ok So I recently bought a 'full body' invisible shield for my iPod Touch 2nd Gen and I installed and made sure I did everything right. So I let it dry for 24 Hours and almost all of the bubbles went away and it looked good so I started using it, but I noticed that there were smudge marks on the Outside of my screen not the sticky side! Anyways can some one tell me how to clean it Please!
-Thanks in Advance

Q: How do I remove fingerprints, dust particles and oils from the invisibleSHIELD once it's been applied to my device?

A: We recommending using left-over SHIELDspray for cleaning the invisibleSHIELD that is installed on your device. Please do not spray SHIELDspray directly onto your device. We suggest spraying a Micro Fiber cloth and then gently wiping & cleaning your device until you are satisfied with the results. There is enough residue left in the bottle to allow you to refill it up to three times and have the same effect.
