Lately I've noticed the trackpad on my MacBook Pro has been getting stuck from time to time and generally isn't as clicky as it used to be. It feels to me like there's something stuck behind the trackpad there that's stopping it from moving freely, but I have no idea how to get behind there and clean it, let alone how anything could have gotten in there in the first place. The trackpad will press all the way down on the bottom left and right corners, but towards the bottom centre it does not press down nearly as easily.
Has anyone had any luck cleaning behind the MacBook trackpad? If so how did you do it?
