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.
