Warning: I am neither a biologist, nor a journalist. My reading of this is naive, and is posted simply to draw attention to a study by seemingly reputable scientists. Seek qualified opinions, this may be nonsense.

There is a preliminary report, posted on 17th March, which seems to find that lower concentrations of alcohol are effective against SARS-CoV-2.
I’m not qualified to have a meaningful opinion on this, but I’ll post it here to see if anyone can shed more light on it.
Notably, both tested alcohols, ethanol and 2-propanol were efficient in inactivating the virus in 30s at a minimal final concentration of at least 30%https://www.biorxiv.org/content/10.1101/2020.03.10.986711v1.full
Points to bear in mind:
- This is only one study.
- I may be misinterpreting the results.
- The study was conducted in laboratory conditions, rather than the real world.
- The study has not yet been peer-reviewed.
The implication, if true, is that alcohol such as Vodka or Rum could be used as a sanitiser for hands and surfaces, particularly relevant given the current shortages of pharmaceutical and industrial products.
All advice is that hand-washing with soap is the most effective way to destroy SARS-CoV-2. However, where running water is not readily available, an effective hand-sanitiser would be the next best thing.
My own approach is currently to act on the findings in this study, but as a last resort.
Hand-washing with soap is, by far, my first choice. A hand-sanitiser that meets WHO standards is my second choice.
If neither of these are available to me, then I’m using a small spray bottle filled with some 40% alcohol (by volume).
