I’ve talked with a few of you about what I did to whiten my white LEGO bricks. It works for any colored bricks as well. Basically pour hydrogen peroxide into a clear container, add some oxyclean and let it set in the sun for hours. That’s it. here’s the full post from my experience –
Anyone tried a UV light to whiten? Here she goes?
We need to make the Retrobrite experiment a Q4 topic. EVERYone with a collection could have this problem.
I tried with limited success. It be never seemed to bring back the full color, but I wasn’t using very powerful bulbs.
I have seen on instagram a few people I follow use a hydrogen Peroxide treatment and a UV Black light. This has worked for them but is very time sensitive. One person left his soak for a bit too long and ended up with an almost milky white color.
Yeah, I worries about that. I saw Brick Tsar ruin a full load of clear bricks. My results were extremely good. Whitened yellow whites and significantly brightened a few severally yellow greys.

I did not use the oxyclean as in @joshhall blog, but what I read, this only accelerates the chemical reaction. I would also recommend rubber gloves and a ladle or something similar to scoop and flip.
