Water damage, is it saveable or thrash?

Hi! I dropped my Nokia 6 into a river while we were at an ATV course for the defence forces. The nokia was on and i forgot to turn it off as i was too busy trying to dry it and get the excess water out. The best thing i could do and also did was in the evening put it into the dryer room. I took the phone apart this weekend and there was a few spots of dried up watermarks, and cleaned the whole motherboard with IPA. There were NO blacked or burned looked components. Is the phone saveable? I will need a new home button assy and a charger board, but is the phone otherwise thrash ready, or should i try to save it?
