Getting back to factory is not all that easy as they use industrial processes.
You can polish up to 3000 grade then a bit of mothers...that will give you a non mirror finish....but you have already gone through the original finish...hence the bright bits..so saving it is going to be a non starter really.
It removes all of the original finish which is the only way to go when they are showing that kind of wear.
Once the original finish is compromised I prefer to aim for a mirror finish, as this will offer the best protection against future corrosion.
A coarser grit will leave a more satin finish.
Thanks for the replies everyone! I’m not too bothered about getting them perfect. I’m wondering if taking some fine wire wool or scotchbrite to them would knock down the scuffs then a rub down with T-cut will give them a decent finish.
I don’t really want them polished, I prefer the brushed look anyway…
I did a set of middleburns by polishing them using the usual process and then using scotch pads. Then I added the logo back using a black paint fine tipped pen

Rubbing sanding paste (the one used to wash greasy hands) with water has worked well for me with seat posts. It removes most of the small stuff, and makes the bigger stuff less visible, while not affecting the overall finish.
