| View Full Version : Shelf life of dyes in methanol wildbillbugman 04-03-2008, 10:16 AM Hi, Anyone care to venture a guess as to how long a solution of dye in methanol can be kept in the dark? Thanks, Bill Kirk Keyes 04-03-2008, 02:47 PM Bill - I'm sure it depends on your dyes. Anyway, I'd try using glass bottles with teflon lined caps to give maximum life.
