Cleaning the intake manifold.

[62barsoom]

How about oven cleaner to get the intake manifold gunk off. Can't hot tank aluminum. Safe on the aluminum I believe, but what about the plastic part?

Soak in this for about 12 hours

Oven cleaner is pretty harsh stuff, very hard on aluminium. I just got a bunch of brass brushes and used hot soapy water and elbow grease.

I use Purple Power and dilute it with water. Soak it for 12 hours, shake it around, brush it, put it back in for another 12 hours. I pressure washed mine after it soaked. You could take it to a self serve car wash. A few bucks and it will be clean.

I've some simple green aircraft cleaner, I use in the ultrasonic cleaner. Sounds like a day soaking in that may be smart. I've a bunch of the little brass brushes. Thanks everyone.

I use oven cleaner to strip anodizing off aluminum and it'll etch it too so I wouldn't go for that. I use a combination of three products:

1. Simple Green in a spray bottle at a strong enough concentration that it sorta makes you cough and wince at the same time. Sauce it heavy and then attack with electric toothbrush. I do this not because it works the best but because it's cheap and sheds the initial filth layer.

2. Goo Gone in spray bottle form. The acid does what the alkaline simple green doesn't, and it's in oil form so it soaks into the grease. I let this sit for a couple minutes then dive in with the toothbrush again.

3. Berryman brand carb cleaner. You can use another brand but nothing melted my gunk like the Berryman. I use this as a final rinse to blast everything else out.

Simple Green is very corrosive, especially if you don't get it all washed off. If you have a polished aluminum surface it will instantly dull it.

Why can't you hot tank aluminum?https://www.speed-talk.com/forum/viewtopic.php?t=20372

Yes, Simple Green makes an aluminum friendly product. I’ve used a diluted regular SG on aluminum, just not too long. What about a can of degreaser?

Throttle body cleaner works very well. Alas, it ain’t cheap…….,
