iPhone 4 gelli cases moisture spots?

I bought the case mate gel case for iPhone 4 before I even got the iPhone. I love it even now. But there are these moisture spots on the back of the phone underneath the case. Neither the phone or case is wet or is even touched before I put the case on. These spots ruin the otherwise awesome look of the case. Anyone have any ideas on how to fix? Has anyone else had this problem?

this does not only happen with water, drinks, etc it happens with sweat and oil as well! so just wipe both the phone and case and it should be fine. happens quite often for me...

Yeah I've tried that. Meticulously wiped both the inside of the case and the phone before putting the case on and they're still there...
