a disaster

Try cleaning the a1200 edge connector with a pencil eraser. Chances are the water may have caused mild oxidation on the goldfingers, or left a residue causing bad connectivity.

If you have anything suitable to clean the female connector on the accelerator you could try that too.

I'd recommend removing any ram from the accelerator whilst testing - it's just one more thing which could be wrong at the moment, and doesn't help you pinpoint the fault.

The fact that it is cycling through grey-black screens could be a good sign, rather than just being completely dead.

Is there any activity on the keyboard - try pressing the capslock key multiple times - does it "lock" on after around 8 presses?

Check the battery on the accelerator - any signs of leakage?

Don't get the soldering iron out just yet!

Hope it all works out

I was looking for a more technical answer that's why I gave the example of the floppy drive.  If we know the exact thing that's happening when water is poured on electronic equipment, we can find the best solution.

Oxidation and deposition

If oxidation of tracks occurs this can reduce the cross-sectional area of the track, thus increasing overall resistance in the track, thus increasing heat dissipation per unit track lingth and increasing the chances of a burnout at some critical higher-resistance point (a narrowing, a track corner, etc) or where the track is transferring a higher current.

Where there is deposition (as I believe someone else has already pointed out) this may cause shorting, or increased interference where complete shorting does not occur.

Both oxidation and deposition may also prevent conduction at any point where contact is required, eg edge connectors, chip sockets, etc.

At least, that's my interpretation of possible water damage modes.
