Best way to clean back cover?

[Cartman]

I keep my phone in a FitBag. It is a nice case and helps keep the phone clean....or at least it did with my 1520. I recently noticed that the back cover on my white 950 XL has started to turn a slight brown in places. I think it is due to the FitBag but am not sure. Used my white 1520 with a FitBag for over a year and this never happened.

Any recommendations on what to use to clean it?

I use Zeiss lens cleaning wipes that are for my glasses. I do have a clear rubber "case" that's more like a grippy thing so it doesn't slip in my hand. I wipe that, the glass, the camera lens, and occasionally take it off and give the white part of the phone a good wipe down. There's nothing more gross than a grimy phone. Makeup is nasty and I can't stand looking at another woman's makeup smeared phone. Ugh!!
Oh, and I'm on my second clear case - I figure for $8 I can get a new one every few months. I love my pretty white phone and don't want to cover it up.
