Success with vinegar as an organic weed killer

We use white household viegar (straight) to control weeds in sidewalk cracks around our town library and have some success with it. First, in the spring, we pull the weeds as best we can and then immediately dribble the vinegar along the crack. It will keep the cracks clear for a while, and we may have to repeat the procedure only once or twice in the season. We check on them every few weeks so we are always treating small plants. Also, we are careful not to use the vinegar near the outer edges of the sidewalk, where it might impact the adjacent soil.
