Galaxy note 2 has water damage?

Last saturday I got my galaxy note 2 wet at work, and when i tried to turn it on, everything just fluttered on the power up screen and then the screen would go black. I dried everything out, and it still didnt work, tried all 3 of my batteries. I left it there taken apart and about 15 hours later the next afternoon I thought what the hell and I tried it and it worked magically. I left on vacation and it has been working, ive been switching batteries in and out as usual and its been working fine, until this morning, over a week after the initial damage, I switched my battery and the same old problem arose. The screen flickers and moves up to the right upon startup, then goes black. I didnt get it wet or drop it or anything, is it finally dead? I tried drying it out again to no avail. Was i lucky it worked this long or can it still be saved for the last couple days of my vacation? Should i leave it out for a while again or is it useless? Probably not going to take it all apart and clean it, so you can save your time typing all those instructions out. Thanks!
