There is probably nothing you can do. I would say there is nothing you can do, but there's always some amazing story of recovery, or someone will come along with a miracle story. So, except for a miracle, the BlackBerry is on its deathbed. That's the thing with liquid exposure: if it doesn't kill the device outright, corrosion sets in and it eventually does kill it.
If you do catch a BlackBerry in time and it was just water, remove the battery right away, and dry the device very, very good (usually by nearly a week in dry rice), there is a high chance of recovery. But your situation isn't so good.
Wish I could give you hope. Sorry.
