I was really hungry, so I decided to eat a sandwich with mayo. It was delicious, and gravity decided that my Macbook needed to taste a little bit. Some mayo went in the gap between the trackpad and the case, and i couldn't remove it without tearing the Mac apart.
The repair was as easy as taking a candy from a baby. With the guides on the site, i was able to do it in less than 5 minutes.
DON'T EAT WHILE YOU'RE USING A MAC.
Other than that, there isn't much to say: it's a screwdriver, place it over the top of the head, then turn it anti clockwise.
