spilled wine on keyboard

This may be OT but this list has been very helpful in the past. I have the official Pro version of SuSE 7.1 and would like to install it on a Dell Inspiron laptop that a friend will give me. It is out of warrantee. Someone had spilled wine on the keyboard. It works if you hook up an external keyboard so the internal circuits are ok. Any suggestions on how to proceed with the cleanup? Does the keyboard on the laptop came as one unit or are the keys integrated to a circuit board? Any help would be appreciated.
