Vapour blasting would be the best way. A dishwasher will corrode aluminium as it is caustic.

[meritlover]

No it wont. Whatever alkali is in the powder gets rinsed off and there is nothing in the dishwasher to react with the aluminium causing it to corrode.
Ive done cylinder heads,oil pumps, manifolds, aluminium pans and it works a treat.
