intake manifold cleaning gone wrong

Im trying to clean my intake. I soaked it in degreaser overnight not even thinking about the annodized aluminum. Now its all black and powdery. What do I do now? The inside is not that clean, and I really dont want to polish it all off. I was thinking about just painting it at this point. Any suggestions?

THanks Chris.

I don't think the intake manifold is anodized, it's raw cast aluminum. What was the degreaser agent you used?

Yea these manifolds are cast and not anodized. I'm not really sure what to tell you to do on this one.

The Victor Jr on my hot rod took a ride through the machine shop's parts cleaner and came out with this grey/black film on it, probably what yours looks like. Anyway, I used a spray cleaner from "Circle K" auto parts that worked just fine. I think it was a wheel cleaner.

Might be just as easy to use the de-greaser setting at the car wash (the local on here is SImple Green) then pressure wash it. I'd be pressure washing the insides anyway after spending the night in solvent.

is it just the carbon that broke loose? if it wont come of i would think you could hit it with some aluminum brighter acid or some aluminum wheel cleaner let it sit for 30-1min no longer and powerwash it off repeat till you get the look you desired just dont let it sit on for no longer then a 1min

Purple power is good non toxic cleaner, even thou it says keep away from painted surfaces I dilute it and use it to clean all sorts of stuff, and you don't get in trouble if it gets in the drain and it won't kill the grass.
