How do you remove scratches from the back of an iPod?

It should come with a cleaning rag. You can add a little bit of amonia free windex glass cleaner to a paper towel and that should clean the screen really well and the wipe it down with the rag. That's what I do. The back gets scratched REALLY easily, so don't worry. If it will really bother you get a protective sheild.If you so get a case make sure you take it off before you clean the iPod.You can also clean the case,just spray a little bit of Windex on the front and on the inside and wipe it with a paper towel really well.Remember NEVER clean your iTOuch with water!
