So I expected this as I have friends with iPhones and I see it on their phones. Smudges! I hate smudges! So normally I just wipe it clean with a microfiber and it looks pretty good, however that does not always remove all the oils caught on the screen. I would think that over time, the oils sitting on the screen will end up degrading the screen or make it look nasty later on. I am wanting to clean it and not sure what to use. I have a cleaning kit we use on the document scanners at work. It has microfiber pads and a cleaning chemical which after reading the ingredients is just isopropyl rubbing alcohol. I heard the HTC Hero has a special coating on it that keeps it resistant to scratches and makes smudges easier to clean. My concern is that the isopropyl alcohol will beat up that coating. So after beating around the bush...the question is, what is the best way to do a good deep cleaning of the screen?
