Helen Cherry said: “If you eat things in brine/vinegar (like olives etc), rather than pouring the salt water or vinegar down your sink, pour on the path, it’ll kill the weeds.”
Fiona Kessack-Morrison commented: “I used kettles of boiling water to kill weeds on my patio last week for the first time ever after 20 years of gardening… amazed at this simple solution! This week the driveway is getting the same treatment.”
Julie Barnes replied: “White vinegar and washing up liquid kills all weeds. I don’t use anything else.”
