black matte/satin wheels stained white - etched?

[makjur]

I have a tacoma trd pro with the factory trd pro wheels on it, which are a satin matte black
I used to clean everything myself but for the past few years i have just been running through washes due to lack of time
This staining has gotten worse and worse, I tried to do something about it the other day, and nothing I have in my arsenal is helping.

aside from mild soap and wheel cleaners, the last thing i tried was some meguiars compound on a microfiber and trying to finger the surfaces. Also tried glosswork glaze from chem guys.
one wheel is untouched, while the other pictured i tried the polish on
I'm starting to think that I need to machine polish these things, with all the angles and surfaces I'll have to plan on having the wheels off the truck

Anyone have any experience with this?
didnt find much searching on here

Almost looks like they were acid etched/compromised from high ph/caustic chemicals/cleaners.

I know some wheel cleaners will do that to some Porsche matte black center lock wheels and center lock nuts.

I'm not 100% that you will be able to bring them back fully without repainting/powder coating.

I'm sure some others will chime in!

Are they clear coated? I know satin is tough when polishing, because you can lose the “satin”. The glaze won’t correct, it’ll just fill in imperfections, maybe, if at all because it’s Chemical Guys.

Unfortunately, I suspect that Sizzle Chest got it right and they will need professionally refinished. If they were mine, that's what I'd be looking into.
