Mine's sunbleaching at this very moment. Today's is the 1st session under the Spanish sun of June. I hope this is the most effective moment of the year for this kind of work.
As you can see, besides covering the font lens for reflecting sun rays, I tried to cover as much body surface as possible, as these days' temperatures and sunlight are so strong that I try to avoid as much overheating as possible.
My only worry is regarding diaphragm blades lubrication and whether they could be affecting by being under such a strong sun.
The "clumsy" aluminium foil covering allows for a perfect setting to point the sun as straight as possible.

You could disassemble the lens, remove the yellow glass and leave it alone in the sun. The bleaching is also faster because the sunlight is not filtered by the other glass elements.

I'm afraid I'm not brave enough to perform an operation of such a kind...

djmike, I didn't take a photo of before (so I can't be in a position to document the process), but all I can say is that it worked very well: after 5-6 sessions of aprox. 4 hours the lens was fully bleached. All must be said: the yellowing was very subtle, aproximately affecting half a stop of EV. (maybe SMC's, being the newest among Taks, are the lest affected by yellowing).
What surely helped is the fact that the summer solstice of June is the best time of the year for taking advantage of the sun's UV radiation in the northern hemisphere.

I think it is obvious which one was taken with the more yellow-ish Tak and which with the UV-treated Tak.

Nice solution, especially to use LEDs. LED's don't get warm like the sun does
