Well, I have done the completely undo the computer keyboard for cleaning and was very successful.... two things I can suggest.... a digital picture of the keyboard before you start.. this is so you don't have to rely on memory as to where the keys go, should they fall out... I put mine in a dispan and washed them... I have been typing all my life but you would be surprise how automatic it come and when it comes to putting them back where they should be, how short minded one can be.... The other tip is I used isopropel alcohol and Q-tips for the cleaning of the hardwired part, or what some call the circuit board.
Good luck, Betty in Va.
