iPad 3 - water damaged LCD

iPad 3 LCD unit has water inside. It works fine, but there are cloud-like configurations on the screen. Can I separate the LCD and the backing and dry it? if yes how?

Is there another way to dry it out?

It seems taped shut. Is there a guide that I missed?

Background information: the iPad fell in a fresh water fish tank, was removed quickly.

I opened it up and dried it out. Any wet spots were treated with isopropyl alcohol.

all seems to work fine, except the remaining water in the LCD unit.

Thanks for any help,

M
