Preventing engine oxidation

So my engine has some pretty bad looking aluminum oxidation but the good news is that it comes off super easy, like almost too easy with just a rub of the finger. Thats fine but what can I spray or put on the engine and the aluminum parts to prevent this from happening again?

Wow, that looks fantastic! Made me want to polish mine a tad...

Mine are not bad, I've been using simple stuff like Aerospace 303 and meguiars engine dressing which actually seems to help quite a bit to "seal" the alu from oxidation.

Have you ever cleaned your engine bay prior to this? I mean spray down with a hose and APC etc?

No but I will be shortly. I have everything including a mild degreaser on the way but it is being held up in the mail due to the current outbreak

Yes, they were powdered wrinkle black by a local race shop. I am not sure if I wanna polish yet as everything you see there was done by hand with a wire brush, gives it a nice brush look up close

What did you use to remove the oxidation? I'm having similar issues, yours came out great.

Just rubbing with my finger and a wire brush. Be careful with the wire brush so you don't scratch up the valve cover. A little masking tape will protect anything you don't wish to brush 👍

Instead of using a wire brush try steel wool. You can easily do a light scrub with some polish in the area and it will keep it just as shiney.

Great Idea! Will likely be much easier to get into the tough to reach spots too!

Had a go at this last night with just a shop rag and some WD-40. Came right off. Will probably do another pass then try the steel wool/polish method. Making me want to take everything apart and hit all the aluminum I can get my hands on..

Same here. When I put an under drive pulley on my car or supercharger(if I can ever find a used MS pulley lol) I will be taking almost everything off and cleaning + conditioning whatever I can get to. I like the steel wool idea as it's hard and to use a brush around the top of the engine around the stacks and down on the alternator.
