iPod touch Keeping Screen Easy to Touch?

[Superperson]

Hello, I have had my touch since September and I love it to death. However, recently it has become harder and harder to drag my finger across the screen, as it is no longer "soft", and rather creates friction. I often will feel something that feels like a gunky coating of the screen. When I leave the screen covered when I'm not using it, it is nice at first, but then in a matter of hours gets gunky again. Is there something I can do to make it easy to touch like every other touch I've seen (including the ones at the Apple store, which I can imagine get abused WAAAAY more than mine do)?

Do you have a protective shield over your screen? Have you considered a stylus? I'm a bit obsessive and just wipe my screen with a microfiber cloth often.

Don't laugh, but "wash your hands" before you use it. Chances are whatever is gunking it up is coming from you. Greasy skin? Hair gunk?

I'm a guitar player. I always wash my hands prior to a set. Keeps my expensive guitar necks from getting gunked up. Bad enough that I sweat like a pig when I'm playing.
