My wife met this couple that I think has something to do with her church at the recent local wine walk festivities that a little booth set up holy moly krakamoli that they get sold a bill of goods
I have spent (too) much time researching this subject, and have worked with residual bacteriastats for years before the coronavirus crisis. (Yes, I said bacteriastat. There isn’t yet a word for products that prevent viral presence.)
Scientific advancements can happen rapidly, especially when money meets powerful marketplace needs.
That said, these products need some very specific environmental circumstances to work, and are rapidly rendered ineffective if contaminants aren’t regularly cleaned from the surface.
Tests show impressive results, but to the best of my knowledge, independent tests aren’t yet available. I am aware of a product that EPA has allowed approval for some very narrow airline applications.
All of this is for a product to restrict viral activity on surfaces, which does zero for human to human spread, or airborne droplets.
I think that the resulting false sense of security it might create offsets it’s narrow range of benefits.
