What's best to clean Intake runners/manifold with?

[Losiracer2]

I'm doing my headgasket, and while I'm waiting for the machine shop to resurface and rebuild the cyl. head, I'm stuck w/ no car, so I can only prep. the block for putting the stuff back on.

What i'm asking is, Whats the best cleaner/degreaser to use on the inside of the intake runners...to get all that nasty gunky oil gooo outta there? Something that breaks it up immediately when I spray it.....any ideas? It's pretty bad on the inside:

B12 chemtool, but you will still have to work with it a little bit.

I used aircraft paint thinner. it took it off fast as hell

don't aircraft strippers eat into aluminum? I use carb cleaner, $1 per can

it didnt eat away at the metal when I did it.

[cb9tuner]

carb cleaner and some light moderate elbow grease to get it completly clean

but with the aircraft stripper, you just spray, let it sit, & hose it off

After with no water.....Just used a rag to wipe it down. The things it could do with a pressure washer.

After.....same as before, no water involved just wiped it down with a rag.

Carb cleaner or brake cleaner work perfect, but you will a few cans

no offence but the aircraft stripper wouldve gotten off that stuff that the degresser didnt

Aluminum jelly works very good from my experience.
This is what my intake mani looks like off the civic's f22a1 turbo.




lol


Luckly I'm porting this manifold out anyways though.

And this was my accord one after I cleaned it.

so this aluminum jelly.....what is it exactly? like a putty you put on there and leave it sitting for 10 min? I could use paint stripper, thats how I got off this pink paint that was on my H23 plenum on the outside, its just the insides i'm worried about damaging. Not to mention, that stuff BURNS my skin when I got like 2 drips on my arm, ouch. But I guess it is really strong.
