Take a 1/2 cup of salt to one quart of boiling water and mix well. Once the salt has completely dissolved, pour the contents on the sidewalk weeds for an immediate result.
Once you have killed the sidewalk weeds, preventing them from coming back is just as easy. Take regular table salt or baking soda and sprinkle on the area where the sidewalk weeds were once alive. Repeat this process once a month for clean sidewalk cracks.
