I've got a couple of pints of elderly pickling vinegar in the shed. When
the weather clears, I'll brush them on. Anyone tried it as a weedkiller?

This particular piece of kitchen sink chemistry is harmless and won't get
you into serious trouble, nor will it kill many weeds. You would probably
get better results clubbing them to death with the bottle!

It will work after a fashion, but you would be a lot better off using a
proper chemical like glyphosate that was intended to to kill plants.

Conditions are obviously different in Ontario, Canada, where
(1) The growing season is only 8 or 9 months per year,
(2) Glyphosate has been removed from the retail market, but
household vinegar (5% acetic acid) is an effective weed killer
on our gravel driveway.
