It definitely kills grass. I use it for both grass and weeds outside of the lawn. The recipe is from Pinterest of course but it's: 1 gallon white vinegar (the kind we bought is 5% acidity) 1 cup table salt 1 tbsp Dawn dish soap Mix and pour into a spray bottle. I'm not sure about scotch broom - reading says it's more effective on small weeds, but that it kills whatever it contacts. I think the salt is damaging to the soil, so don't spray it if you plan to grow something else.
