I've seen reports about old mining rig cards being cleaned together in bulk with water, possibly to hide signs of wear. It's possible some never got sold and have aged or corroded over time.

The positive aspect is that it isn't corrosion; it's just oxidation. The negative part is that removing it from the finstack will be difficult.

I'm open to trying it now. Any ideas you have?

It doesn’t seem to be from a mining rig since I reused it from a gaming PC.

isopropyl at least 90% concentration works well for this task. It can be used as a toothbrush or cotton swab. Make sure to take out the entire heat sink or fin stack to avoid harming the PCB.

Vinegar performs well, but for better results you could start with isopropyl alcohol. Since vinegar doesn’t really remove grime from metal, it mainly prevents rust formation.

No signs of water harm on the PC, but it might have been exposed to high humidity instead of flooding.

It really does remove the aluminum oxide, effectively cleaning it. However, it doesn't halt oxidation; what prevents it is eliminating the oxygen.
