Clean the impossible clean

Have you ever wondered why consoles and computer keyboards turn from near white to yellow or a yucky brown even when no-one in your home of office smokes? Well the plastic used is a tri-polymer called acrylonitrile butadiene styrene or ABS and the reason it goes off colour over time is the addition of a flame retardant in the form of Bromide. It was thought that this process was irreversible but the people at RetrOBright have discovered how to restore those old cases to something like their original look. You cannot buy this stuff in the shops but the recipe, instructions and an explanation of how it works can be found on the web site. Very interesting but not for the faint hearted.
