I have a feeling that the environment the parts are kept in have a great deal in determining how their color changes.fst72vette wrote: ↑Sun May 20, 2018 12:08 pm Its weird how these new parts yellowed over the years. I wonder if the plastic packaging or sunlight causes this .... makes you wonder ..... hmmmm
Update - I thoroughly and faithfully tried the Distilled H2O & Bleach technique today. It did not work for me. I cannot tell if the pieces are any better or possibly worse than before. The best I can tell is the bleach technique may have removed some green tint, but added some brown (pic below is comparison of test bumper after all my attempts). I tried 3 separate times, with new water/bleach & iced water each time. The parts began to looks worse to me. Plus, the process is quite nasty. I then boiled them in straight distilled water 2 more times to try and "clean" them out.
However, since I have stock pieces outside in a peroxide bath, I took a deep breath and dropped in my RPM transmission and front bumper. So far, no green, and the pieces are appearing to whiten. Crazy. I have had luck with peroxiding RPM parts before, but I have also had them turn green. Seems to be a bit of a crap shoot.
