Replying to IPhone problem

I just got a new iPhone and with it I got a screen cover/protector. To apply the cover, you needed to use a liquid solution for it to stay on. However, when I was applying it, some of the solution got in the phone and there is now a "blotch" in the bottom left hand side of the screen. Nothing to serious, just some discoloration and a major piss off. Any tips on how to fix this? It's not under warranty, since it's considered water damage. I have been blow drying it and putting it in a bowl of rice. Anything else I can do? Any help is greatly appreciated.
