Tough Q.
Each person’s definition of “sanitary” is key here, especially since you use the word in your main Q.
I am a (now) unapologetic slob. My home is just that, my home. It is cluttered and messy, the floors are rarely clean, the dog is a champion shedder and I swear that as soon as I vacuum he shakes out a full new dog of hair everywhere. I wear my shoes inside, I hate hate hate dusting, and I don’t wipe down the counters all the time.
That said, any surface that touches food is always clean, my clothes are clean, my bedding and towels are clean.
That is not enough for most people, and they are horrified that my toilets, full of hard water stains, don’t sparkle, and that there is usually some dust on my bookcases.
I’m sure my house smells a bit in the winter because it is closed up and the dog gets wet and also farts.
I don’t invite any but the closest friends over anymore because judgement is harsh about such things, and there is a conviction that sloppy or messy equals lazy or spoiled or generally lesser in value.
Which is where “sanitary” comes in. Because my house is not tidy, and the floors are dirty most of time, some people think the space is unsanitary. It is not.
I have been uncomfortable in spaces where the concern for cleanliness is made obvious, where a fuss is made if I put something on a table, or drape a sweater over the arm of the sofa where I am sitting; and sometimes the fumes from strong cleaning products give me a headache.
And anyone (and there have been some here) who make harsh judgements and describe how clean they are because “some of my friends are immunocompromised”, well bullshit. I am immunocompromised and just fine, thank you, in my little mess.
The difference in styles doesn’t really bother me, the inevitable judgement does.
Well put, @linguaphile.
