Ah! That
explains my lack of results. I soaked the keys for five or six hours. They got clean, but
didn't change color very much. Sounds like I pulled them out too soon. Several days,
you say?
Has anyone tried a glass/plexi-glass bath w/ UV lights? It might get
expensive if you want UV lights that are dimmable (to control strength) but UV lights and
ballasts are not that expensive. A simple timer and maybe a reflective surface on the
enclosure and you are good to go. Then real experiments can be done by varying exposure
time and concentration of the solution to see if there is a happy medium. Problem is you
need someone with lots of yellowed parts that they don't mind experimenting on/ruining
in the process.
