How bad is it?

You can use a dremel with soft pad and autosol for a fast solution then finish by hand with cloth and more autosol.

For deeper it’s increasingly fine wet and dry then1000 grade wire wool then as above.

Or you you can drive a lorry and frantically polish in your cab on your breaks but you run the risk of looking like a pervert to passing motorists.

Ask mike Muz.

They don't look too bad..
Similar procedure to THM for me.
I would probably start with 1500 grit paper, then finish with a polishing compound something like Autosol probably with a polishing wheel on a highspeed drill if you have one.
They will come up nice & shiny assuming you have the patience of course, it ain't no five-minute job.

Either that or sell them and let someone else sort them out.. 8)

Funny, I was about to start a post on this very thing, but for some Middleburns.

I found this useful for a Campag seat-post I polished last week - came out a treat.

It seems you need to know first if the part is anodised or not.

it does appear to have some sort of laquer on there.
