I can't believe the sunlight trick works. My brain always thought it was the sun that made it yellow! I saw this first on the Retro Recipes channel a while back where he shared some theories on the maybe how's and why's. (https://www.youtube.com/watch?v=8P1OVj0IcqY https://www.youtube.com/watch?v=8P1OVj0IcqY) I was very skeptical, but I tried it out on my very very yellow Nintendo Famicon, as well as some smoker-teeth-yellow keyboard keys on an old Roland synth... left them out in the sun for a couple of days (2x3hours). It worked really well on both my test subjects! Certainly not perfect "retrobrite" white - but much better than I expected.
