So I had my first ever attempt at whitening some yellow plastic this past day.
I had bought some super yellowed controllers with hopes to experiment and see if I could turn them white. I know from reading around there is retrobrite and all sort of methods to getting yellowed plastic white again. So I decided to try an inexpensive route to get the few super yellow controllers I have white again.
I bought a EXO Terra reptile UVB200 (PT2340) bulb and the cheapest hood I could find at my local pet store. I think the total cost was around $40.
I then picked out a box that could house whatever I wanted to whiten. If it was a Duo-R shell or controller or whatever I can fit them in my box. I then lined the box with tinfoil with the shiny side visible to me.
I cut off one of the flaps on one of the sides of the box. I mounted the lamp to my server rack facing down into the box on the side I cut the flap on.
I then bought "permanent coloring creme developer 40 volume" from my local hairstylist the last time I was getting my hair cut. The 32oz bottle cost me $10.
I then spread the 12% peroxide creme over the controller halves and set them in the bottom of the box. I read that the creme will evaporate so and read that putting some saran wrap over them will prevent that. So, I put saran wrap over the two halves making sure it was smooth as possible.
After about 12hrs I took the two halves out and washed them with water. I wanted to do a better time lapse but fell asleep at some point working on other stuff and woke up and it was done.

End
I think the total cost would come out to around $60 or less. But I now have all the stuff I need to whiten yellowed plastic and I still have a ton of the creme. I barely used any on the controller halves, I just put a little on my gloves and smeared it around then saran wrapped it.
