I just got a almost new Edelbrock intake ($42 on Ebay) it's not very dirty, just a few smudges. What works best on these rough cast aluminum manifolds for a touch up job?

Thanks............

use some aluminum wheel cleaner on it. so long as it isnt stained up too badly it should help a lot

Carburetor cleaner & a toothbrush will get grime off.

what about antifreeze stains? My water neck leaked fluid on mine and I can't get it off.

Like cableguy said...... I used Eagleone aluminum wheel cleaner. It has acid in it so be careful what you get it on.

Baking Soda and a Sandblaster

What about ebgine degreaser,engine brite whatever its called....cleans up greasy parts good.
