Manifolds, transmission cases, etc…..

Any tips on what concoctions, methods work to get it brightened up? Better off to just paint it with a quality aluminum paint? I don’t own any sort of blasting equipment to go that route.

“Aluminum brightener” is a pretty common recommendation. Seems to be just some sort of acid treatment. Wondering if there’s a household equivalent. I also wonder if will just oxidize and look the same after a few months.
