SD Hat Rehabilitation
A few years ago, in response to a hint (alright, a threat) from a station commander, my somewhat faded and slightly green SD hat was given a new lease of life by immersion in a bath (without black hatband and badge, or chinstrap) in a solution of Dylon "Saxe Blue" cold water dye. Results were amazing, and convinced station commander that it was not a new, but an infinitely better, hat than the one he had complained about. Googling Saxe Blue dye now doesn't appear to appear in UK, but is available in Australia!
