I would hardly think that the Dee biologists would tolerate Somers / Orvis / various local vets offering a disinfection service which was not effective on GS.
I hear what you are saying 100% but I have a strong distrust of disinfectents having seen several fisheries down south fall victim to disease because "dips" as recommended by various govenment bodies did not work.
GS canot survive away from a host for more than 7 days in the wet, 5 days being the norm. 2 days of drying at 20 degrees will kill it dead. One hour at 60 degrees will also do the same.
It also cannot survive a strong salt solution as already pointed out. If anything, salt would be the most effective control of it.
The problem I have is that the disinfectents recommended are Virkon, which although being effective against the likes of blood bourne pathogens, such as HIV, Hep B, TB etc, it does not appear to have been tested for parasites. ..it is purely a Virus/Bacteria/Fungi killer....and the other is Wescodyne..which is a "general" disinfectent which is recommended for cleaning hospitals etc.
The recommendation is to "mix" the above disinfectants then add salt and sodium hydroxide (caustic soda) to the mix. Out of that lot, the salt will kill it, the Caustic soda will rot your gear and the two disinfectants will kill bacteria but not the parasite.
I would personnally use the salt or the drying, preferably both as both are proven methods not just in fishing but in fish keeping and aquaculture for the removal and destruction of all sorts of parasites.
