You chose the wrong condiment from the chippy. Table salt would be a
more effective weedkiller (although sodium chlorate would be better
still).

I use cooking salt to kill the weeds that grow in the pavement cracks.

I've used white vinegar along with a pound of table salt, mixed together
with several drops of dish washing liquid. Although it must be
sunny when its applied and no rain forecasted for a day
or 2, Ive found it works and its cheap. Just watch where you
spray it since it will kill anything green.

You might think that by doing this you are being environmentally
friendly, but the energy used to refine food grade materials makes it
every bit as bad as using diluted glyphosate weedkiller. The weeds
killed per unit of energy used is far higher with a proper weedkiller.
And the safety margins with glyphosate formulations are very good (the
wetting agents in commercial formulations are the main threat).
