now the internet says that uv light combines with the flame retardant bromine to
make plastic yellow. and it has a pic of a super nintendo and now i remember my
snes getting yellow on the bottom after i let my kid use it.
howtogeek also says using h2o2 doesnt stop it from happening again and might
make the plastic brittle.
whats weird is they say to use uv light to help the process.
i think in today's 3d printer age people would be better off getting new parts
printed if they want something new looking.
