Yes spill some soap and water on it🙄.
Seriously though your warranty is done for so you should at least remove the keyboard then the individual keys. Then you could clean it with a damp sponge or cloth, not sopping wet, and let it dry for a day or two.
Because of all the potentially corrosive materials in the Red Bull I would disassemble the computer and thoroughly clean everything with any residue on it. If anything requires more than a damp sponge you could use distilled or deionized water and let it dry for several days.
For any amount of water make sure the computer is unplugged with the battery removed and be certain it is thoroughly dry before reconnecting.
