I've used lamp oil (white gas?) in the past with success in removing gasoline stains.

You can also by cast aluminum spray paint that looks very nice and is more durable then the bare cast finish.

It it's off the car, what about the heavy duty acid-type wheel cleaners?

The best way I have found to clean cast aluminium intake manifolds is using a media blaster. I find glass beads work the best. This should get rid of any stains or paint that have accumulated over the years.

If you don't want to ever have to do it again, I highly reccomend powerdercoating it too. On all of my aluminium parts I used Eastwood's satin clear podercoat which I was more than satisfied with. Noxt exactly the cheap route to go, but I have found few other methods that were as durable.

I agree with bead blasting, it worked great on my original Z28 manifold. I had it sprayed with clear by my painter afterward but that started to chip, discolor and stain after awhile. I wish I had known about the clear powdercoat back then.

I read in a post a while back to try corn starch and a toothbrush (not the one you use every day).

Does powdercoating of aluminum cause additional heat? John Z.

Rob, I've had pretty good luck washing them with laundry detergent and hot water. Before media blasting them we would wash them with this solution to get the oil/grease/gas out of the aluminum pores, and most of the time they came out looking new. Even if you plan on blasting or painting it you should wash it first- it'll keep the oil from seeping out into your fresh paint or finish later.
I had the best luck with Tide, really hot water and a medium scrub brush. If you do blast it, fine steel shot gives the best "as cast" finish. Sand or glass beads make it too smooth.

A K&N air filter cleaning kit comes with a water soluable cleaner that works pretty good at removing stains from an aluminum intake manifold. I just use it, a toothbrush, and a rag.

trplblk: Nearly any form of coating that you add to the manifold will act as an isulator (You can think of it as insulation). It will not necessarily cause additional heat, it will just make it more difficult for the heat to escape (Through the manifold). I have never had any issues with anything I have powdercoated (Blocks, heads, transmissions.. etc.)
