I'm not sure if Dowicide is even available for consumer purchase any more. The active ingredient in Dowicide is/was pentachlorophenol (PCP, but not to be confused with angel dust), which is a carcinogen, and often an environmental contaminant found at wood preservation facilities.Dude, that sucks.
I actually have a couple pair of shell that are out of rotation until I have a chance to do a full glycerin treatment. I’m still trying to source Dowicide antimicrobial to add to the distilled water/vegetable glycerine solution.
