So I recently found my childhood SNES and it has turned yellow. I’ve seen this happen to a lot of consoles online and I know how to remove the yellowing, I’m just wondering why and how it happens?
In: Chemistry
ABS plastics are infused with bromine which is used as a flame retardant. Over time exposure to UV light causes the brominated plastic to yellow; it can be reversed by submerging it in a hydrogen peroxide solution and UV light.
