You DO NOT have to disassemble your Macbook Pro. Just go to Radio Shack and purchase a can of NON CONDUCTIVE COMPONENT SPRAY and spray down the keyboard and everywhere that you can find an opening. Don't worry, remember it's NON CUNDUCTIVE Spray which means that electricity can not discharge so all of your internal components whould be safe. I recently had the same issue with my 2010 Macbook Pro i7 which you already know cost a small fortune. I used the spray and allowed the MBP to rest for 1 hour preferably in a warm location and that was it..Keyboard works, mouse pad works, usb works...Don't pay Apple $1200 for something you can do for your which cost only $12 per can.
