Would it hurt to try dissemble it a little and spray contact cleaner basically everywhere ?? I know they have water damage stickers they will have activated so its to late for that, but would the contact cleaner make things worse ?
I had some luck with reviving water dropped electronics using IPO baths. Contact cleaner contains propane which is barely solluble in water, while IPO mix with water in all proportions. Nice IPO bath followed by some time in dry, moderately warm spot, surrounded by paper towels or silica packets will dry up most/all humidity from under the components and ICs.
