I use 1 quart vinegar to 1/2 cup of dish soap. It works well on sunny days
but is not a permanent solution. The weeds come back so I spray about once
a week.

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?
