I used a paint-spraygun connected to the building dry nitrogen line (as the compressed air source) and filled with isopropyl (sp?) alcohol to FLUSH the entire keyboard assembly clean. This obviously should be performed in a well vented area (fume hood!). Isopropyl alcohol is harmless to the keybaord (and most other microelectronics) and has in all the cases I've participated in solved the problem. Walt K.
