I stole this wholesale from the good Dr. Joy Bliss at Maggies Farm. She writes:
"This is from an Asst. Prof in infectious diseases at Johns Hopkins University. In our community chat, here, they sent this excellent summary to avoid contagion. I share it with you because it is very clear:Be sure and read the whole thing.
The virus is not a living organism, but a protein molecule (DNA) covered by a protective layer of lipid (fat), which, when absorbed by the cells of the ocular, nasal or buccal mucosa, changes their genetic code. (mutation) and convert them into aggressor and multiplier cells.
Since the virus is not a living organism but a protein molecule, it is not killed, but decays on its own. The disintegration time depends on the temperature, humidity and type of material where it lies.
The virus is very fragile; the only thing that protects it is a thin outer layer of fat. That is why any soap or detergent is the best remedy, because the foam CUTS the FAT (that is why you have to rub so much: for 20 seconds or more, to make a lot of foam). By dissolving the fat layer, the protein molecule disperses and breaks down on its own.
HEAT melts fat; this is why it is so good to use water above 25 degrees Celsius for washing hands, clothes and everything. In addition, hot water makes more foam and that makes it even more useful.
Alcohol or any mixture with alcohol over 65% DISSOLVES ANY FAT, especially the external lipid layer of the virus.
Any mix with 1 part bleach and 5 parts water directly dissolves the
protein, breaks it down from the inside.
Oxygenated water helps long after soap, alcohol and chlorine, because peroxide dissolves the virus protein, but you have to use it pure and it hurts your skin.
NO BACTERICIDE SERVES. The virus is not a living organism like bacteria; they cannot kill what is not alive with anthobiotics, but quickly disintegrate its structure with everything said."
