Rick, Use a very mild acid. Body shops sell such a product but
vinegar works well. Media blasting scars the finish and dulls it.
Polish it up with a chrome polish and wipe it clean with the acid.
The dullness is oxidation.

Subject: [Mgs] Cleaning aluminum
Hello Friends,
Merry Christmas and all the other salutations of the season!
I write to you this Christmas Eve to talk about engine restoration.
Specifically, I want to ask about cleaning aluminum. I have always used
cloth, steel wool or ScotchBrite lubricated with WD40 or lacquer
thinner and
I like the results. However, the finish does not look 'new'. I'd
like to
know a technique to get that really clean white-aluminum finish of
freshly
cast aluminum. I've tried media blasting but the shop I visited used
steel
balls not glass, plastic or shells. The result was a dull gray
finish that
I didn't like. I ended up painting the part with 'Cast Coat Aluminum'
engine paint - a sad, second-class solution, if attractive.
So today I ask; How does one get that 'new part' aluminum finish?
best regards,
rick
