Has anyone tried uPVC cleaner to remove what appears to be nicotine stains from video games?
I have several gameboy games which appear to have nicotine stains and have seen quite a few games and cartridges from Japan that have similar stains. It's not yellowing, it's brown and spotty (not consistent, with big drops or splotches in places).
There's a youtube video of someone cleaning plastic jukebox trim with uPVC cleaner. The stains look similar and it seems to remove them pretty easily.
