Have two microfiber cloths. A green fuzzy and a smooth yellow one. I damp a small spot for each with hot water. I clean the case first and edges from the screen with the smooth one. The fuzzy microfiber then finishes it up for the entire screen. Very fast process. I clean it every 3-4 days depending on the condition. Takes less than two minutes with half the time waiting for the water to turn hot. I sometimes can have my OCD streaks where I don't even touch my phone for a couple days and just use my PSP w/ a 32 GB to do my multimedia stuff. Yeah, I know it takes less than a commercial break to clean it, but I can get pretty OCD when I want to. I am starting to get tired of all these slab form factors looking pretty much the same and invites so much germs and grease to our screens. It doesn't look like this trend is going away anytime soon.
