I recently spilled milk on and around my MacBook. Powered down immediately and wiped off the excess, left to air out for 24 hours, and it's fine now, but the dried milk stiffened the little bit of foam around the CD/DVD drive opening, making it difficult for the motor to push discs out. I was thinking about dampening a pipe cleaner with a mix of water and alcohol to try to clean it. Any thoughts on that or other suggestions? Thanks.
