I can't win, first it was dust now I try and protect the screen that has dust under it and I get soapy water with the dust..

I just put the invisible shield on my device and it looks great But, during the process I got a little soapy water under the screen and now I have streaks. Before anyone says anything I put tape over the buttons but for some reason it still got under the screen. I tried to open the device by removing the screws but I couldn't pull it apart. I even tried to put a a blade in the upper left hand corner where the battery goes but it still will not come apart.

Any help would be greatly appreciated

Thanks
