How do you get the sandpaper in there?
You could probably just use a dowel with some cloth, or a battle swab or something. Smear aluminum polish all over it, chuck it in a drill, and just spin the thing inside.
or something like a flexhone would work too.
for removing tiny burs, I guess sticking a tiny piece of sandpaper to your fingertip and just sliding it in there couldn't hurt.
