I used a pencil eraser and brushed the crumbs off, then cleaned lightly with Magic Eraser and wiped with a microfiber cloth. After that I used some black dressing applied lightly on microfiber, wiping lightly over the white scuff marks. I think I could use Mother's Back to Black and it would help.
What I did worked pretty well and made the scuff marks nearly unnoticeable. I need to get a more uniform "dressing" to cover the blemishes in the plastic, then lightly buff it out by hand. So far it is a big improvement.
