This is a short, but very good article about why soap and water is more effective on Corona Viruses than santizers.
Chemistry Professor Explains Why Soap & Water Works

Quoted from a different article:
Alcohol works — to a degree
To sum up, viruses are almost like grease-nanoparticles. They can stay active for many hours on surfaces and then get picked up by touch. Then they get to our face and infect us because most of us touch our face frequently.
Water is not effective alone in washing the virus off our hands. Alcohol-based products work better. But nothing beats soap — the virus detaches from the skin and falls apart readily in soapy water.
From a friend that has a doctorate in biology and decades in Molecular Biology labs & research:
So two structural types of animal viruses, with or without a lipid (fat) layer on the outside (there are many other internal differences between viruses, e. g. the nucleic acids and types of proteins, etc). I disagree with the term "most" having the lipid layer since not all viruses have been determined structurally. The without lipid layer, like hepatitis, are resistant to detergent and hand sanitizer effects because the primary action of these two is to disrupt the lipid layer and influence infectivity of the viruses containing the lipid layer. If the lipid virus have screwed up or missing lipid, it can't get in your cells then they are done. The ones without the lipid layer are not affected by the detergent and sanitizer (effective ingredient is usually 62-70% alcohol optimally for all pathogens (usually isopropanol) and remain infective for the most part. However, the hand washing with detergent serves primarily to get goop off your hands etc (and all organisms associated with the goop), and also interact with all cells that have lipid or fat in them including bacteria, fungi, single cell protozoans like malaria, and non cell lipid containing viruses (but not viruses lacking lipid).
(Don't ask me to translate. ) "Goop" is a technical term.
