If you don't like NYT, googling the same question provides many other choices.
This article is oddly more specific to Logos (ha). I'm frankly not young, and thought I knew about soap. Dishwashing, laundry, and millions (I'm sure) of commercials. But I didn't. Well, ok.
- How would you discover 'soap'? Turns out, the most likely answer is animal sacrificing. Though, BBQ'ing would also seem to work, except for the grill. Remember those little drippy things on your average altar? (the Logos connection!). Fat and other stuff flows off, plus ashes down below. Soap! I've never seen altar cleaning; I assume it was left to assistent-priests.
- Soap literally attacks organisms (the part I didn't know). Due to the molecular structure, it accidentally pries into membranes of bacteria and viruses. The latter, I would have doubted. I knew it's great for oil removal.
- Hand sanitizer is similar; it just doesn't clear the 'battlefield'. Dead bodies everywhere.
So! Take another look at altar-technology (bronze age maybe)!
