Why does the white shirt have a green mark on the collar with a necklace, and it can t be washed off

Is it a copper chain?

The green one is patina. Try it with white vinegar!

I also saw a way to clean the patina. Yes:

Green hairs are formed because copper is oxidized and rusted, resulting in patina. It is basic copper carbonate. Wipe the patina directly with gauze or scouring pad dipped in a little toothpaste, do not wash it with water after wiping, and wipe it directly with a cloth or napkin.

It is better not to use salt, this substance has strong corrosiveness to copper, and if it is not cleaned, it will produce patina faster.
