Cleaning Cast Aluminium

[richardm6994]

I'm starting to look ahead and at cleaning the aluminium cast body of the Eaton supercharger.

 

It's in good condition, but nevertheless it is 'dull' and shows some signs of white oxide.

 

What would be the best solution for cleaning the charger body to bring it up as new? I don't want to dip it into any solutions because I don't want anything going inside the charger body.

Soda Blasting - just make some blanking plates up for the inlet and outlet.

Sorry to disappoint Nick, but there ain't no grease left in these elbows at the moment..., maybe in a few months lol

Alloy wheel cleaner might work?

[Bob Tucker]

Start with cellulose thinners to remove crud & oxides

I use these guys (they are local to me but may post). They have aqua blasting equipment for aluminium and steel.

I used the acidic type alloy wheel cleaner with success on an alloy casting, it's the type that actually dissolves the surface of the alloy so you need to be careful and not leave it too long!

Abit extreme but I used to clean cyl heads from Duetz deisel engines in a caustic solution after degreasing with hot pressure wash ,after 30 mins wash off with lots of water they would come up like new but dont forget they are in there ,did it once left some in o/night all that was left was valve guides and seats!!!!! mick

Would wonder wheels work, I used it with excellent results. Easily cleared the yellow tarnishing on my alloys and left them really clean.

As silly as it sounds, cillit bang works wonders on aluminium

[Guest shaggy]

Not at all surprised, cillit bang is lethal

[megadodo]

Surely it should be.... BARRY SCOTT'S CILLIT BANG! By the way I've never found the turbo charger in the bottle and yet the ASA still allow the ads to run.........?

Haha, whatever they put in there brings Ali back to a gleaming finish, with a bit of rubbing with scotch brite! Just wear rubber gloves, it makes any little cuts on your fingers sting for 3 weeks minimum.
