I'm not bashing you, I'm just saying you are taking things out of context. Bleach is alkaline, vinegar is acidic, they both push the normal ph about the same amount towards the extremes--just in opposite directions. The effects of bleach (or soap) on cell membranes and other direct "attacks" is something else again. Bleach physically attacks many things including the wallpaper or paint
or plastic of environmental surfaces, and as such it may be less suitable as an environmental cleaner in hospitals.
Then again, considering the state of septic control in most hospitals, I'd have to question the attention paid or research done in any of them. Yes, there are many secondary infections still needlessly killing hospital patients and even in ICUs I've seenplenty of them that could not pass a simple white glove inspection. How yours was? I don't know.I do know that most hospitals are good places to get infected because they just don't practice basic hygiene unless someone has forced them to do so.
There are exceptions, like the Hospital for Special Surgery (NY) which has been putting entire surgical teams in moon suits in order to protect ortho surgery patients. They're not the only ones--but they are among the rare ones that take infections seriously.
Check out Biohazard Level 4 decontamination procedures if you want to talk about clean and sterile. And on the way there, you'll find bleach--not vinegar--used at the more casual levels. Neither
one is good enough for BHL4 but if you ask anyone in that end of the business, they'll go for bleach over vinegar every time. And unlike hospitals, they're quite serious about results.
Hospital disinfection? "While the Centers for Disease Control and Prevention estimates there are 1.7 million hospital infections and 99,000 associated deaths each year, he says, those numbers don’t calculate deaths caused by, rather than merely associated with infections patients get in the hospital. "

You take a petri dish, you take a microscope, you'll see that vinegar is better than water, but best as a salad dressing.
