What is the best way to clean the polyurethane smart covers?
Hate the polyurethane Apple "smart" covers, but for some reason Apple did not create leather smart covers for the iPad Air. I know there is a leather case for the Air, but it's too bulky. I like the smart cover concept, but the polyurethane gets really dirty and smudgy and gross.
What are best ways to keep this thing clean without ruining it? Thanks!
iPad Air Wi-Fi, Cellular, iOS 7.0.4
