These would work if it was the OP that caused the wear mark, but doesn't do much good if it was from someone long ago...
The only solution I see if you want it to look nice would be to take off the anodizing and polish the whole thing, which would be a lot of work, and I assume this would then require more work down the road keeping it looking nice since exposed alloy will need cleaning and re-polishing more frequently.

This is spot on, thanks for it and all the other great replies.
The crank was recently acquired on the auction site, to be put on a '91 Crosscut I'm building for my Seattle daughter-in-law. The frame will be powder coated in her favorite color, turquoise, so looks is a definite factor. Black Selle T-Series saddle and hoods, silver vintage 105 parts.
Try not to shudder, C&V purists, but I may even use some type of special effect in the top coat, like this;
Prismatic Powders: Tropical Breeze with Baby Rockstar Sparkle Top Coat
Powder coating the crank is a neat idea, but I think I will either leave it or strip it.
Maybe strip it and then have my powder coater apply some type of clear coat?
The only thing left to locate is a set of silver wheels with the ability to accept an 8 or 9 speed HG cassette. 105 hubs would be ideal but not required. SS spokes, silver rims. I'm looking to give her
many gears in order to tackle any Seattle/Cascade Mountains terrain. RD is a 105 long cage, shifters are bar-end 8/9's.
Does oven cleaner work better than a paint stripper, if I decide to strip it?
