There are different grades of micro fiber.. The really soft yellow is what I like I stay away from the green glass micro fiber.Microfiber scratches plastic though so I would keep it to the glass only. I use a T-shirt or just leave it dirty.
As i do on my guitars...
@eascross you could also use car wax.. Just a light coat over the glass.. Makes it easier to wipe off prints...
I just pour a little whiskey on mine, use a lighter to ignite the excess and blow out the flame after 10 seconds. Germ free!
