So I have read and watched about the technique of applying Hydrogen Peroxide to yellowed plastics on old computers and such
then leaving them out in the sun to revert them back to their original white color. So I have wondered if anyone on here has done/tried out
the restoration process of this on ceiling fans such as the Emerson Designers/Friction Drives/ Yellowed Blades, etc.
As the guy says, he doesn't know if the result is permanent and if the plastic will still contain its integrity, but I feel like it would be a nice
result to try it out.

I am wondering this as well... the blade flanges, switch housing/switch cap, and canopy on my 42" Plastic Emerson (Designer) are severely yellowed from sunlight. Hydrogen Peroxide is cheap and easy, so if this works, I may have to get myself a bottle and try it.

I believe it was Tais who posted about this YEARS ago on this board somewhere. There was mention of it working with a black light, I tried it on a slightly yellowed plastic Emerson switch housing and I honestly think there were minor improvements. I don't have before or after pictures, and it's still yellowed, but it kinda went to a more even cream color than sun-faded yellow. You'd probably get even better results in the sun, I was doing it in the middle of winter so setting it out in the sun for a prolonged period wasn't really an option.

A backlight may also be a good idea.

I've had some people suggest Retrobright to me,, for removing yellowing from cordless phones.. Never tried it,, I question what it does to the integrity of the plastic..

A lot of people have asked that, and it is undetermined for sure. Someone should make a video on the progress of this with scrap plastic. |

I saw a video years ago with someone reversing the chemical reaction to plastic that yellows over time on a Super Nintendo.. I believe baking soda and some other things mixed does the trick.. Note I haven't looked at the video the OP posted..
