Ridding Mum's driveway of weeds.

A few years ago it was simple - sodium chlorate.  Now that's been banned, you can try Roundup but IME other weeds will spring up to replace the zapped ones.  Sodium chlorate used to stop anything growing for six months.

I use a simple solution for dandelions in our garden , on a hot day it kills them within 1 day.   Get one of those small 1 1/2-2 ltrs pump up hand spray bottles, £ shop had them I think.   pour in a bottle of NEAT malt vinegar, IIRC Lidl/Aldi are about 40p a bottle, (maybe 30p?) , then put in a squirt of neat washing up liquid (acts as a surfactant), then replace lid, give it a good shae, give it a few pumps, and away you go. Spray at the base as it kills the roots, but remember it will kill anything elase as well. Works wonders on slugs and snails as well, (just don't watch).
Tests were done, with neat vinegar, diluted vinegar, and the above. Guess which was best.

I'm sure the USAF must have some Agent Orange left.

Spray at the base as it kills the roots,

You can also spray on the leaves of the weeds, as the crease on the leaves act as a funnel to
let all liquid (rain or weed-killer solution) drain into it's digestive system.

Stupid question can I get away with white vinegar?

Sounds like a job for industrial strength non-brewed condiment...

I am finding malt vinegar truly awesome against weeds (and ants).
