I have 2 microfiber cloths. Usually I use just a dry one to wipe any dust off. But when it is needed I dampen one of the cloths with water and use it to clean finger prints and what not off. Then I use the dry microfiber cloth to wipe the damp off and give it that final loving touch.
I just use a damp cotton wash cloth then dry with a cotton hand towel. If there is something tougher than water will handle I dampen a cloth with rubbing alcohol.
