Shirt sleeve.... for random "get those prints off" ...
I do have a microfiber cloth and cleaning solution as well.. but, only do this once per week, or whenever i feel like it..
currently no screen protector either.. I've been looking at sgpstore.com .. but, they don't have Fascinate screen protectors yet. I'd really like to try one of the Ultra Crystal or the Ultra Oleophobic screens. Other forums report that the Ultra Crystal is about as close as you're going to get to the same feel as the glass on the phone... (which, I'd prefer.. don't want my finger getting stuck on a tacky surface).
