I've also found, but never used, "retrobrite 3%"(can't remember the
link, but a google search should bring it up), which uses standard
off-the-shelf stabilized 3% hydrogen peroxide, compared to the near
full strength counterparts. it seems this also has less risk of
bloom...maybe less is more?

im no expert, but it seems that fluorescent light and
tobacco smoke
seem to be the two contributing factors to the yellowing process. I
also stored my computers in storage where they had high-pressure
sodium lighting and 6 months to a year later it had yellowed shadows
where something wasn't covering it. i've also noticed computers in my
garage yellowed, and i'm thinking that chemical outgassing from
petroleum products/other household chemicals may accelerate it. I
think re-yellowing can be reduced by using incandescent light in our
"museums" and making sure the air is clean, and not stored in the same
area as these products, but nothing is to say it won't re-yellow.

So what do curators do about this sort of thing?
Do they just let it yellow?
I'm not a curator, but it seems to me that there's nothing to do about
any yellowing that has already occurred, and that slowing down further
yellowing is no more complicated than keeping the artifact in a box.
If it's an artifact you're keeping on display, where it is exposed to UV
light, then it is going to continue yellowing.
