A good explanation. The first few tweets are included here, but read the entire thread on Twitter for the complete picture.
2/25 The soap dissolves the fat membrane and the virus falls apart like a house of cards and "dies", or rather, we should say it becomes inactive as viruses aren’t really alive. Viruses can be active outside the body for hours, even days.

4/25 Consequently, many antibacterial products are basically just an expensive version of soap in terms of how they act on viruses. Soap is the best but alcohol wipes are good when soap is not practical or handy (e.g. office receptions).

6/25 I point out to that while I am expert in supramolecular chemistry and the assembly of nanoparticles, I am not a virologists. The image with the first tweet is from an excellent post here which is dense with good virology info: https://t.co/73TurPhxOE

8/25 The RNA is the viral genetic material -it is very similar to DNA. The proteins have several roles including breaking into the target cell, assist with virus replication and basically to be a key building block (like a brick in a house) in the whole virus structure.

10/25 Instead the viral self-assembly is based on weak “non-covalent” interactions between the proteins, RNA and lipids. Together these act together like a Velcro so it is very hard to break up the self-assembled viral particle. Still, we can do it (e.g. with soap!).

How about, in that case, contain i g the viral; plague by having the media and Democratic talking heads wash their mouths out with soap?
Interesting, though, on how hospitals still have to pressure staff to wash their hands after using the bathroom and between patients. I can remember even in the transplant wing of the hospital where my son had his transplant there were hand sanitizer jugs mounted on the wall outside of the door of every individual room and staff would come in to see him without using them.
