Nope,I was in a generic home supply today and I looked at several cleaners including simple green. I was actually looking for a soot eraser and the "magic eraser " made me think about Elizabeth Montgomery (then I thought about her and Charles Bronson on the Twilight Zone) And, to my surprise, it worked.
The track in the first photo is actually jet black.
To rewind a bit, for a change I got lucky with the rotor can. The 16-D anvil (?) Fit in just enough to be able to close the gap enough to repair it. More on that later.

I'll post them under that forum soon.
