If you can get hold of some polishing mops and compound pastes to use with a dremel/drill, that would be ideal.
Otherwise use some wire wool to get it a bit finer, then cover the whole thing in brasso/autosol and rub it in slowly till the aluminium starts to react/dissolve (it will turn dark grey) once you have it all like this get a rough rag (like a tea towel) and polish like crazy (shoe shine style)
It should then look fairly shiny, but finish it off with a soft cloth/sock/buffer which will clean of the last of the polish.
Remember youll have to do this every so often as the alloy will form a whitish oxide (go dull)
