Otterbox Case cleaning methods?

I have the commuter iphone case and it has the rubber part, the thing is its getting really dirty and i want to clean it but don't know how, its teal and blue so i can't really bleach it.

Usually a semi-damp cloth will do. Don't use any detergens or alcohol as that can degrade the rubber and plastic as well as cause discoloration. Any stuck lint pieces can be cleared out with some scotch tape.

Also make sure you take the phone out of the case before cleaning it.
