Crank shaft rust

Hi all
About 6 months ago I had my crankshaft polished need due to a seized engine
I covered up the crankshaft but I’ve come to install it and found I’ve got a light spots of rust on some of the journals , I thought I’d coated them in oil ☹️☹️
Obviously I need to remove these spots
Can I either use a fine grade wire wool or 1200 wet and dry paper without marking the journals
Or does it have to go back the the machine shop

Thanks Jim

Don't use sand paper or emery cloth. Really it should be remeasured but if with wire wool you can shift it and it looks ok you might just be lucky, I would remeasure it for if there are any defects it's better to remove them now than find a bearing has spun with the secondary consequences from that (new conrod and/or line bored block or new block if you already have O/S OD bearings).
