Care to point to Amazon(or other sites) product pages? May be useful for some of us looking to buy.

Windex sells lactic acid cleaner readily available in stores. It's the yellow stuff, it looks like pee but it does the job.

Is that the same as windex vinegar? That’s what we use as our low-level cleaning agent.

Vinegar is acetic acid.

Nah, the vinegar is the clear stuff. The yellow stuff is labeled "Windex Multisurface" I think (no "with Vinegar") and is clear yellow, not perfectly clear.

Almost all household cleaning sprays use lactic acid. Its smell is less irritating than acetic acid, so presumably you can inhale more of it until you cough...

My friend started a company that sells high pH water for cleaning/disinfecting. https://phurwater.com/science/

What on earth is high pH water? Water has a pH. If something has a high pH it's not water.

According to the company's documentation it is basically (hah!) a pH 11-12.5 solution of sodium hydroxide, aka lye: http://phurwater.com/wp-content/uploads/2015/12/MSDS-Cleaner...

You can call this water insomuch that it contains water (kind of like wine)

So basically, you can pay $22 to have them mix an unknown amount of NaOH into 32oz of water, or you can buy 5 lbs of NaOH off Amazon for $19[1] and mix it into water yourself. A lifetime supply of "phurwater" for less than the price of a single bottle, without even shopping around--this was the first search result on DuckDuckGo.

What incredible crap.

200 PPM if their MSDS[1] is to be believed, but damn. This is the best marketing I've ever seen for the most inane product this side of a dodgy ICO.
