I too have checked in on this thread periodically, and it seems now to have 
gone awry.  Early on, someone suggested that another group had discovered that 
sunlight would work to reduce/eliminate the yellowing. I did a little search of 
the Yahoo Camera Fix archives and found a whole raft of posts on the subject. I 
think most of these folks were dealing with Pentax Takumar lenses, many of 
which are yellowing as they age.  Bottom line is that the sunlight treatment 
works - the yellowing is reduced/eliminated after a couple of weeks of exposure 
to sunlight.

Here is a couple of URLS: 
http://groups.yahoo.com/group/camera-fix/message/9081
http://groups.yahoo.com/group/camera-fix/message/9399
and there are many more posts in the same general area.
