The 3% HP I use to de-yellow is quite harmless and easy to get. Don't get me wrong, I wouldn't suggest drinking it. Napisan sounds like an interesting alternative but the viscosity would annoy me...
You dissolve it in warm water, there is no viscosity.

I had some luck with some old computer parts, dissolve a bunch of the product in warm/hot but not boiling water in a clear container, put the item in the water, stick a clear lid on and put it in the sun.
