I don’t think I’ve anything new to add to what I’ve already written about the sensitizer stability in my Cyanomicon, which can be freely downloaded here:

I’m not responsible for PF’s quality control - or their instructions. If the dichromate is omitted the solution will begin decomposing within six months or so; with dichromate the shelf-life is several years.
