OK, so I googled Virkon S. Some talk about it being the sterilizing pink stuff mixed with water, the fumes can go up your nose.
In my wine kit, there comes a pink powder that is used for sterilizing the wine apparatus, watch out if it goes up your nose, I wear a mask. I can bet it is the same stuff, but I think this in the wine kit goes by a different name. Hmmm....some food for thoughts here. Have a wonderful and great day, Cindi
