Based on the chemical etching on the black rims… I’d say this is the result of heavy carwashing (like the tunnels) or the owner is using the wrong cleaning chemicals with super hard, mineral dense water. That doesn’t look like a basic coat of rust dust, that looks like a full on chemical reaction.
This comment for the win! 🍻 Going on 12 years at a Premiere Porsche dealer and you’d be surprised how badly the wrong car washes, wheel cleaners, and God forbid tire shine treatments that ruin the finish on wheels, calipers, lug bolts/nuts, and tire sidewall cracking.
Hell one of the largest national dealer vendors tried getting shops in our area to switch to a new version of brake cleaner, and it was literally melting the seals in the Wurth brake clean spray bottles! We also got the wrong wheel cleaner once and luckily my boss and I were there that day so we of course when WTF we gotta check if this is bad for our cars or not…tested it on a totaled car at our body shop located behind us and damn it might have been straight up acid.
Lot of those products are too harsh, especially if they advertise will remove brake dust or bugs without scrubbing or the like, then it’s usually too good to be true and gonna mess your car up either soon or long term if you keep using the bad stuff. Like how no detailer will use Armor All! 😉
I’ve washed many cars and yes. Aggressive wheel cleaner in action right here. Or an aggressive alkaline overall shampoo.
Aggressive cleaners are supposed to be used rarely once every 5 or 10 washes but since they make the cleaning job so easy they are used by lazy car washers all the time. The result is corrosion of unprotected metals, trims, plastics etc.
OP, You’ll be surprised how much worse it is to wash your car at cheap or even worse ‘automatic’ washes. And how long it can stay ‘new looking’ for if you take it to retailers who know what they are doing.
I heard yesterday the Center Lug Nut on the GT3 RS if using the wrong soaps turn white and really acceptable to damage. And they cost your soul to replace.

That still shouldn’t be able to strip the finish off of a fastener; shoddy coating testing or finance got barking up the wrong tree.

You heard WRONG - it’s your firstborn, not your soul, silly.
