Getting shoe scuffs off door panel

[Laid GP]

I am bad about kicking the door panel accidentally when I get out of my car and it has left some scuffs on NAND around the speaker grill. I used the total interior detailer and scrubbed and that seemed to get most of it off but I am not sure what to do about the speaker grill. Suggestions?

I put some product on a rag and scrub it and then hit it with an interior brush.  SVRT then to cover up anything that didn't come out.
