It's been over 7 years since last time I cleaned any kind of Aluminum and for the life of me I can't recall what I used in the sand blaster.

you can use fine glass bead too, you just need to wash the parts well after your done.

High pressure water with a baking soda / soap blend, glass beads, sand, or even a plastic type media. I used all 3 of these on luminum aircraft heads.

DONT USE ALUMINUM OXIDE !!!!!! It WILL remove much more than the paint. That is a media not to be used without the right equipment and is not to be used on aluminum. It will dissolve ceramic and steel blast nozzles in minutes, imagine what it could do to aluminum. I have to use carbide nozzles and even then the wear factor is insane.

You will want to use glass bead or walnut shell media for paint removal in order to minimize surface damage.
