Removal of rust on a semi delicate object

I got some beautiful ground ballscrew at my scrapyard today
But there are some spots of surface rust on it. Typically i would just sand it off, but I would like to preserve the surface shiny finish if at all possible. Can anybody give me some advice on how to remove the rust, without scratching the screw or anything?

Cigarette ash & olive oil... make a thick poltice and apply it to the area run the nut over several times, wiping the rust off and thinning the poltice as you go.

Works like a charm.

EDIT: You might try toothpaste, not the gel kind but something like the good old fashioned white Colgate creamy stuff. Leaves your screw minty fresh.

toothpaste got most of it off, sure beautifies the screw though. Steel wool will not work because I cant get it into the grooves of the screw. I still have a few specks left that the toothpaste would not get off

Use Naval Jelly, it's a mild chemical etch that will disolve the rust. Follow the directions on the bottle and it should take it off just fine. It was developed by the navy (hence the name) where rust is always a factor.

Extra fine steel wool is a good bet for a delicate surface (along with the above mentioned solvents). I've used it on my car with good results.

I use naval-jelly all the time on auto-restorations. Works great on the rust only, it's not abrasive so it won't grind down any good metal.

Cut a large onion in half and rub the onion over the rust. I learned this on "How clean is your house" and tried it....works like a miracle. Have half a lemon on hand to remove the onion juice smell...wipe with a clean cloth and all gone.

PC2- do yourself a google search on removing rust with molasses (slow, but surprisingly effective) or via electrolysis (very very cool). The mr perfesser in you would really dig the electrolosys thing.

Lemon juice, just wipe it off afterwards. T-cut or Brasso also kick arse.
