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.
