Natural Armor Weed & Grass Killer, 128 oz

Active ingredients appear to be primarily salt, with some vinegar and essential oils. Smells strongly like Worcestershire sauce, fortunately, I like that stuff. 😉 I used it on my gravel driveway and from the top level, it killed all of the spring weeds and grass that had taken route over the mild winter. We got a couple hot days since then, so hopefully it got to the roots as well… Time will tell. I would have concerns spraying it in an area that I wanted later to plant, because salt does build up in soil. (Hence the old phrase “salt their fields) In my driveway I don't care as much. I will likely buy again..
