Best way to "clean" iPod Nano?

[Jonbo298]

Oh yeah. When I went to buy one, I immediately bought 2 diff cases depending on what I was doing. But the 2nd case was smudging the nano so I returned it for a refund. But the other case I have has worked perfectly so far. Except sometimes the plastic front makes the scroll thingy on it go a little nuts so I have to power off nano and then back on and its fine again
