Preparing for a catastrophe: beer accidents

[Elias]

Let's say about 3 dl of beer gets inside a Nord. What should one do?
More specifically, the worst case scenario: It gets on some keys and some sensitive electronics.

So obviously:
1. Disconnect power and any other cables immediately.
2. Start a fight? No. Remove all the beer you can with paper towels.
3. Now what?

Going for first aid here, like: Disassemble the unit and rinse distilled water?

1.5 Go to bar: "dude spilt my rider, can I get a refill?"

Power off, of course. I would immediately invert the keyboard it so gravity starts working for you.
The electronics should be largely OK (once dry), it would be the key mechanisms and contacts that would be the problem with sticky, dried beer.
Anything metal inside will corrode faster as a result, but shouldn't dramatically shorten the life of the keyboard.
Fortunately, a good tech can clean up things, and the damage shouldn't be too severe.
