    Mogie's recipe is perfect, be aware it will kill anything it touchs, including the surrounding plants and grass.

    Horticultural vinegar with the added benefit of the area smelling like a salad for a day or two.

    Heat up 1 cup of white vinegar, mix in about 1/4 cup of Dawn Premium. Not the dollar store kind, because it is too thin. When mixed, pour into a spray bottle and fill with water. Shake

    A mixture of white vinegar, table salt, and Dawn dishwashing liquid will work well. I use 1 gallon vinegar, 1 cup of table salt, and 2 Tablespoons of Dawn. Mixt well, pour into spray bottle and spray on the weeds in the crcks. Within a day or two the weeds/grass will turn brown and die and will be easy to remove or sweep away.

    I just use straight vinegar in my sprayer. I don't bother with salt, water, or Dawn. Works quickly.

    Hi Susan, hoping this helps you out,

    2 cups white vinegar

    ¼ cup salt

    Squirt of dawn

    Mix in a spray bottle. If you have a larger area, you can mix in a garden sprayer with larger quantities. Use when it will not be raining for a few hours so that it isn’t washed away.
