Getting yellowed plastic white again...
ChadTower:
The most famous (to us, anyway) example of widespread yellowing is probably the SNES. Do a Google on yellow SNES and you'll get pages of links.

There's a lot of speculation out there regarding yellowing plastics (especially for the SNES). The most comprehensive article I've seen is at Vintage Computing. The article specifically talks about SNES plastic but it does give examples of other types of yellowing.

I saw a tip somewhere that said to soak trackballs and white buttons in high concentration bleach, like those bottles of Deck Wash from the hardware store. A few days, a few swirls a day and they come out significantly whiter. Nothing can return them to exactly the original color but the bleach does remove at least half of the damage.

Depending on the plastic, it's not the best thing to do. The surface integrity of the plastic is already compromised, swishing it around in bleach might further compromise them and you're going to end up needing to do something else.
