A lot of the claims of homemade cleaners don't add up. If you do the research, it becomes obvious. But it depends on what you want to do. Do you want to sanitize things? Or just make them look clean? For my floors, I just want them to look clean. There's no point I can see in sanitizing floors, unless you have babies crawling on them which we don't. Even then, there's no way to kill off every germ. So I'm not opposed to just using clear water to mop floors. The floors look clean and smell fine, so why do anything more? No rinsing and no residue, therefore less work for the same result.
In spite of popular belief, vinegar does not sanitize things simply by spraying it on and wiping it off. I've laughed at that one for years, after reading in a book by a Dutch oven cooking 'expert' that all DOs should be sprayed with vinegar after use to sanitize them. It just doesn't make sense. If the proper steps were followed to actually sanitize the pots (which shouldn't need it anyway), I've always thought the acid would damage the seasoning, which is the last thing you'd want to do. I would bet letting even a mild acid like vinegar repeatedly stand on laminate countertops would damage those over time, too.
Here's a linky with info about using bleach, hydrogen peroxide, and vinegar (NOT MIXED TOGETHER!) as sanitizers. Note the ten minute standing time on the charts for sanitizing with room-temperature, undiluted vinegar. Also note room temperature, undiluted vinegar is not as effective as heated vinegar in killing listeria and E.coli.

The best bet with homemade cleaners IMO is to try various ideas and see what works for you. I haven't had a lot of luck but every once in a while something exceeds my expectations, and that makes the experimenting worthwhile. I have a chemical sensitivity, so anything I can use like vinegar and baking soda that doesn't make my face swell up or my skin break out or make it hard to breathe makes me very, very happy.
