The best solution is to get a screen protector off of eBay for like 1-2 bucks. You can get a pack of 6 for that much. Then use rubbing ALCOHOL, as in C3H7OH, whenever it gets greasy. Wallah, works like a charm! 1. It keeps the screen oil free 2. You get the slickness back of the oleophobic coating. The glass without the coating isn't slick at all.
