Some very fine sand paper (1000 grit atleast... I think I've had 1600 to use on aluminum) will be needed for anything deep or really bad, then use some type of polish to get it to shine.
OR, polish it, see if the marks show... then sand and repolish if you need to.

I have polished quite a few aluminum posts. I start with ~400-800 grit if there is deep scratches, then 1000, then 2000, then wetsand with 2000. Then use Mother Mag and Aluminum polish until no more black crap comes off the post. At that point, you have a mirror finish post.

These ball hones are great and I always use them on every bike I build. Additionally, the "pinch slot" (???) at the top of the seat tube almost always has sharp edges and I go at these with some emery cloth and a small round file. If you get rid of all the sharp edges your seat posts will work much smoother and will not get all marked up.

But if you have access to a buffing wheel, either on a converted bench grinder or a drill motor, you can significantly speed that process up. I would go from ~400 to 1000 grit, then polish it up with a 6-in spiral sewn buffing wheel (cutter) using brown tripoli compound. The results are fantastic, but you have to make sure whatever anodise clear coating is off of it before you start sanding and polishing.
