So this is what happened...
The other night I took a 1.5L water bottle out of the fridge and I kept it on my dresser overnight while I was sleeping. When I woke up, the moisture from the bottle left a pool of water around the bottle. It just so happened that my phone was laying in that water for about 6 hours. None of it went into my phone because the case was on it, but the iSkin case now has permanent stains on that case that I cannot get out. Picture is below. Would anyone know of anything that would remove these stain marks all over the back of the case?

I have a lifetime warranty with the case, so I can exchange it and get a new one, but I'd like to try and fix the issue if I can.
Any help would be much appreciated.
