Thats how aluminium rusts.
A brass wire brush and some self etching primer for high temp applications should work. Mask the gasket surfaces.

Just get as much off as possible with a brush. The acid in the self etching primer will eat through and chemically alter the oxidation.
To be sure try a little on the bottom and see how it finishes.
