Hello everyone! I would like to share my experience restoring old computers to its original (or close to) beige/grey colour.
If you are reading this post, chances are that you know what retrobright (or retr0bright) is. In any case, here is a short explanation: ABS plastics were largely used in computers and game consoles in the 80s, 90s and early 2000s. Plastic manufacturers mixed bromine within the ABS formula to give these plastics fire retardant properties. With time, these ABS plastics turn yellow due to a chemical reaction between the bromine and UV light (radiated plenty by the Sun and also fluorescent lights among other sources).
