You're right about a stylus helping remove grease pencil in the groove BUT grease pencil is what I use to fill some digs before transferring a rare record to another medium. It works but only as a temporary measure. The stylus will cut a new channel through the very malleable pencil mark and play through (well enough to minimize any peaking when transferring to a digital medium - then you can use software to remove the rest without leaving nasty artifacts). This method works well for small digs but will not fill a tapering 2" long crack running from the edge in! That's a whole other topic for discussion.
