To soap or not to soap? Light hearted.

Each to his or her own. I don't see a conflict here, just ways of getting clean!
"So what do you do, CT?" (imagined question that nobody's going to ask...)
I use a sponge (lather with soap, scrub body, rinse). I can't believe I even wrote all this; must be getting old (and that's a whole other story...)

I do recall a discussion in a comedy show about sharing soap. It was to do with where the last person to use it rubbed it and were you rub it first. Their genitals and bottom. Your face.

People tend not to share flannels so I do see the point.

Perhaps it explains the rise in popularity of liquid soap - which also removes he problem of soap going soft and slimy in poorly-drained soap dishes.

Trouble with liquid soap is the plastic it’s in, and the damage that does, which is why many people have returned to using a bar of soap.

I daresay whethertomorrow by the sound of it, the post you saw was written by some obsessive, germ phobia sufferer who's been listening to an influencer or one of those know-it-all people who gets a kick out of publishing misinformation or shall we just call it rubbish. Or marketing.

Best to do what you feel comfortable with, everything we live with is covered with microbes and bacteria as well as microplastics. I remember seeing a tv programme when I was possibly 11 or so, it was about microbes that live on cheese. I refused to eat cheese for months! Possibly wet sponges etc that are left lying about are attractive to moulds, eek, don't tell the Facebook poster!! Joke.

Flannels breed bacteria and viruses unless they are washed at 60° after each use so the person advising their use is the disgusting one.
Using your own bar of soap is fine maybe not sharing it though.

AGA perhaps they only use it once? I do but for my face, I use a face soap using my hands then remove with the flannel. It exfoliates as it cleans off the soap.
I don’t use a flannel in the shower though.
