Granted. Being truly clean will of course demand sterilization. As part of a daily cleaning cycle the house seals itself and becomes an autoclave. The building becomes pressurized and the temperature is raised to 270 degrees fahrenheit for 20 minutes. You’ll probably wanna be gone when it happens.
NYT and WaPo both have articles about it. Paywalled, so I can see why OP wouldn’t link em. I can’t even get the wsj home page to load on firefox with ublock, so I can’t say whether they reported on it at all, but it’s not exactly like nobody is reporting on this.
