How to clean Ringke Fusion iPhone case?

I have the mint green case, and I've only had it for a few days and it's already getting dirty (I guess due to my makeup). I haven't seen any sites or anything on how to clean it and what products to use, so does anyone have any suggestions? I thought I'd ask before I mess up one of my favorite cases.

Use a baby wipe or make-up wipe as this works fine…
