Review: CLEARS EVERYTHING can not be stressed enough!!
Review: I get a lot of weed growth both in my sidewalk and driveway joints, and in my back yard where I have river rock instead of grass. If you are going to mix it in your sprayer, make sure you have at least a two gallon sprayer because the ratio is 24 ounces to 1 gallon of water so you end up with almost a gallon and a half. What I do is mix two gallons in a washed out kitty litter container and use that to pour into my sprayer. I keep a plastic quart measuring cup in my garage and a dedicated funnel. Don't be a guy and mix it in the kitchen! I am very happy with how long it has been keeping the weeds from returning. I've only had to re-treat one sidewalk joint and a few spots in the backyard. Be advised though that this is a ground clearing agent. It will kill everything, including grass and flowers.

Seems, at the first, to be a little slow on the death march, but seems to kill it all.
