I wish I had seen this before I sent my son's MacBook in for repair. My son too had a spill onto the keyboard, although his spill was an "adult beverage" whilst a group of his fraternity brothers and their dates were drinking in his room.
Luckily for me, the repair Genius at the local Apple store is a bud from way back who knew where to find the parts BEFORE sending it to Apple.
If it happens again, I will have at it with my set of miniature screw drivers! Thanks for the article, you have given me the nerve to try it next time. After all, I have assembled multiple AR-15 lower receivers, and that is a huge bag of tiny pins and springs.
