I recently got a GBC and have been cleaning it slowly to try and get it looking pristine. But so far, have been utterly unlucky with the tiny nooks and crannies. I'm less worried about it in the places you can't see.. But as you can see with the pictures below, there are some obvious points. I've been trying to scrub and using alcohol and q-tips and so forth, couldn't get it out. So I went to using some Xacto knives, and couldn't get it out. I'm not sure what to do at this point.
