Have a look at <http://www.fixedgeargallery.com/articles/polishing/>
the author used Jestco Products' #780 Anodize Remover to good
effect. Let us know how you fare.

Sodium hydroxide-based oven cleaner works, but is slow. I used it to
remove green (!) anodising from a brake hanger. Typically the metal
underneath will require a lot of polishing/

Oven cleaner with lye, and a plastic scrub brush and gas mask.

2000 grit sandpaper and simichrome or NEVR-Dull wadding.

Took me 30 mins to make a black seatpost into a polished seatpost.

There is almost no loss of aluminum - i'd guestimate less than 2 grams lost.
