Oil has the funny attribute that while it feels like it’s making you more messy, its slippery properties can help dirt slip away too. So e.g. pouring oil into a clogged toilet can help unclog it. (Sometimes. Don’t sue me if it doesn’t work.) Or how the oil bath around a combustion engine also helps carry the dust and crud away in addition to lubrication.
So I think it just might, although the process is probably more involved than just pouring oil over oneself.
Olive oil is also a part of some soaps, often a significant part - like over 50%.
Wasn’t it more of an oil and scrape process?
Yes, they seem to have had a specific tool for it (a “strigil,” I believe). I was just trying to be succinct so the server would actually let me post the title
Edit: most of my attempts to point out the background info in the title were kinda verbose
