Will platinum turn yellow? Why?

1. The reason why platinum turns yellow is that a certain amount of dirt is accumulated on the surface of platinum after long-term wearing or placing, and irregular cleaning of platinum will affect the color of platinum.

2. The yellowing of platinum is also due to the long-term contact with products containing chemical components such as cosmetics, detergents and hair gel during wearing or placing, which will lead to the chemical components gradually corroding the surface of platinum and the color of platinum will be affected.
