S22 Plus Aluminium frame surrounding camera problem

The aluminium that surround my s22 plus has some dark spots, it wouldnt come off even though I clean it, anyone have the same problem and how to clean it away?

Hi,
Looks like you haven't cleaned your phone once in a few times. It is recommended to wipe with a alcohol pad on the front and back of your phone to make sure it is clean. You may use your warranty to fix this issue if still applicable otherwise you may need to bear with it. Currently I do not have a suitable solution to fix your problem. Please ensure next time to clean it more often.
Hope this helps! 😁

I always clean it

It's this metal frame around the camera, I believe it is call oxidation, I tried using alcohol to clean it but it only faints it a little.
