The recommended vinegar for herbicidal use is a 20% acidity vinegar. It's sold
at better garden centers, and Lowes now sells it. It's very expensive and I
don't use it. I hand pull weeds. Either way, if you use the vinegar, it is
suggested you use the 20% by volume acidity at full strength, no diluted with
water.

My master gardener suggested a solution of vinegar and water for
killing the weeds that come up between the bricks in my patio.
Unfortunately, she's on vacation now, so I can't ask her: what is the
correct ratio of vinegar to water?
