Cleaning the back housing

[dalecooper]

Hello.
I've recently upgraded from a Win Jr. LTE to a Win HD LTE, and hasn't been a week and the white back cover is presenting some darkened areas due to using a Bugatti universal cover (I thought it was not a cheap one)

How could I clean it? Does someone had the same problem?

I've already looked on bluparts for a replacement housing, but they don't ship to Europe and I cannot find anything remotely similar.

Thanks.

I haven't done it on my Blu phone, but on my old white Nexus 5 I used a Magic Eraser, sponge to clean the pores of the plastic. Just dampen the sponge and rub lightly. It actually flakes little pieces of the eraser that dig into the pores. I end up using those things on everything. They really clean plastics, and even cat puke from a leather sofa easily.
