I lost my F6, because of the coffee :/

[googan]

I lost my F6 key of my unibody mac pro after coffee spillage. :/
There was no sugar in the coffee. However there is a remnant of coffee which results the F6 key not functioning condition. I saw some brown colored areas under the key, when I remove it.

How should i clean it. Is using a hypo and some alcohol applicable?
