It's not looking like a stain. The vacuum metallized metal layer has eroded and leaving the plastic substrate used for the boombox.
Vacuum metalizing plastic is a process that allows you to create a layer of metal on a substrate, metal or plastic.
This eroded metal layer cannot be repaired.

It’s not a plastic trim Royce, that part on the M70 is all aluminum and that’s a rub/scuff mark that’s not gonna just wash off. He can maybe lessen the “darkness” by rubbing it perhaps with “bar keepers friend” cleaner/polish or polish it carefully with some metal or plastic polish but the polished area would no longer match the brushed areas.

That is correct Norm!
I didn't click and enlarge to find it was the M70 trim! My mistake!

Looks like oxidized aluminum breaking through the clearcoat.

A better lit picture might help determine what it is and what you can do about it.
