    cleaning the intake manifold and aluminum engine parts

    after rinsing off your engine bay a few times it seems like a sort of corrosion forms on your intake manifold and any other aluminum or metal parts under the hood. you can scrape it off with your finger nail a little bit so it looks like it is able to be removed, i was wonderin if anyone has attempted to remove this sh*t anyhow? maybe with a steel wool or toothbrush? let me know if anyone has any ideas

    It sounds like you're describing aluminium oxide. If so, you want it there -- and whether you do or not, it'll be there as long as the motor is exposed to the atmosphere.
    The world breaks everyone and afterward many are strong in the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure it will kill you too but there will be no special hurry. Ernest Hemingway, A Farewell to Arms, 1929

    Well shy of removing said components sanding off the oxide and painting them good luck.

    Unless you go with chrome or polished stainless replacement parts, you don't want to clean anything off there that won't come off with some water, simple green, and a stiff nylon brush. You could polish the whole thing but you'll still end up with the oxidation if you don't clearcoat it.

    I think painting/powdercoating is your best bet for a low maintenance clean look. Another option is to get carbon fiber dressup pieces that cover up the kinda nasty parts so they're not in plain sight.
