How do you care for your phone's glass back?

Every smartphone fan has their opinion on glass backs, but we think it's fair to say that the community has a love-hate relationship with the material. It looks great, it feels luxurious but gathers grease faster than a burger restaurant's kitchen tiles.
Some don't mind as they use the device with a case anyway. Others will slap a “skin” on the phone and forget about the glass back. There are those that still love to use their phone “naked” and will vigorously wipe their fingerprints off its back a few times a day to keep it looking pristine. And there are those who simply leave it as is — either they don't care about the phone's looks back there, or they were simply defeated in the battle against the grease. In which camp do you fall?
