Does anyone know if you can somehow restore the color of grey plastics that have browned? My PB 180 in particular has noticeably brown keys and trackball buttons that I assume is due to bromine. I'm tempted to perform an experiment though I have my doubts since the usual de-yellowing techniques using peroxides are effectively bleaching, but I'm curious to know if anyone has any experience or information about this.
