more) effective. I doubt vinegar adds anything to the mix.
My preferred weedkiller was sodium chlorate. The EC banned it as "it
remains in the soil". That's what I _want_ a weedkiller to do! IME, the
replacement - glyphosate - which is the main (though in _tiny_
proportion) constituent of all the "named" products, only lasts a week
or two, or at most a month. Not that I'm a gardener: I want it for my
drive, patio, gravel, and the like.

the detergent is a surfactant. I’ve only used water with proprietary
weedkilling solutions.
When I was a schoolboy, salt and vinegar was used to clean big old
pennies - it really worked, we were told that the salt and vinegar

Hmm. I remember from chemistry
"[an] acid + [a] base -> [a] salt + water". Vinegar is already an acid
(dilute acetic), and salt is a salt - the _product_ of an acid.

mixture to be absorbed into the soil structure.
That I could believe. It's a detergent, and probably the cheapest from
household substances (foam bath/shower gel and shampoo being the others;
all three are basically the same substance, with microscopic amounts of
things to make them smell nice or have different colours).
