Back cover discoloration

[vilwen]

 i got this phone a month back. I'm not sure if this discoloration is wear or just some kind of "paint" from my trousers pockets. 

According to a post on Reddit. Everybody out of 5-6 people still have mint condition back covers.

Anybody have a way to perhaps restore the back cover?

Hey @vilwen,
Have you tried cleaning it with a cotton ball/pad with some lukewarm water?

[vilwen]

Yes I have. No effect as far as I can see. Any other ideas?
