What do you use to make your engine bright (Air head)
I tried probably a dozen cleaners, from mag cleaners, welding supply cleaners, Never Dull, etc., and nothing really worked. Oak Okleshen recommended Nice n Easy Storm Door and Screen cleaner but that left a dullness to the aluminum. It has phosphoric acid in it and if left on too long it can stain the aluminum. I've heard people use Simple Green but again, if left on too long, it can etch the aluminum.
The best I found was foaming engine cleaner and/or WD-40 and the Scotchbrite pads...the thin green kind. Don't use steel wool or brushes...you might could try some brass brushes. Maybe you can get some ideas here:

The engine is very clean, its just the oxidation that I am looking to get rid of. Especially on the head fins where I can't really scrub.

I make my own but you can buy it in several grades
many scrubbing mediums leave deposits in the pores........ actual ferrous steel wool is the worst offender........ and will cause never ending oxidation
if you rinse your cases with water after acid..... add white vinegar or they will very likely turn an unpleasant dark gray

I'm sure you'll be able to figure it out
ohhh.... many aluminum polishes leave residues in the pores that will turn a chalky white over time......

the minerals in tap water......... distilled maybe too but I don't know for sure because I've never tried it......
will gray freshly blasted cases unless you add white vinegar
I typically boil freshly blasted engine bits in a big lobster pot to hopefully loosen and remove any embedded media
but only if they will not fit in my big ultrasonic
I used to use a two step wheel cleaner for spoked car wheels, by eagle, one acid and another neutralizer...... seems like it didn't work out well for aluminum because of the discoloration

Even better, I found a product at a marine store named SLX, made for cleaning outdrives and other exposed metal on boats. With much skeptisism, I tried it on the 30 year old never been cleaned front hub and couldn't believe it!! Really worked great. I use it all the time now for all kinds of cleaning. Works great for getting off the white residue that seems to leech from the cases and other parts. And it didn't hurt the paint.
It is phosphoric acid, though, so it must be washed off, and gloves are nice too. It's a thick pink liquid that goes on with a green scrubby and left for 15 or so minutes, then rinsed off. Even have seen a diluted version of it in Winn Dixie for floor cleaning.
