Bitfenix soft touch cleaning

[ELDoGo]

hello everyone,

I have a question for the community and experience builders. I have a bitfenix shinobi case (Purchase it after watching linus tech tips in 2011)  I have had this case for a while now, sealed and boxed. I recently have showed the box to a friend when i noticed a residue on the top of it and spots in front of it. i don't know how it happend, especially when i even have it in its original box and plastic bag over it. It feels like a sticky residue on the soft touch body the case has.

I'm concerned using the wrong product and ruining the rest soft touch of it. 

I'm looking for what to purchase to clean the soft touch without killing the rest of the case.

Is this that soft rubbery coating stuff?  Erm, hate to say it, but it's quite possible it's just the material breaking down with age.  A lot of that stuff ages as well as fresh fruit over time.

Oven cleaner works almost immediately. Spray it all over the surface, you'll have to be a bit wasteful, and leave to sit for half a moment then wearing a glove(or not) work it all around and wash off. If it didnt work then try a different brand just make sure it emphasises that it works on grease.
