Used to clear weeds in between paving slabs and on a resin bound drive. Gave a liberal spray at the mixture suggested and it killed 80-90% of the weeds growing. Mixed up a stronger mix and applied that a couple of weeks later which seems to have killed all but the biggest/strongest few weeds which I’ve since removed mechanically. Like all non-professional weed killers, it works ok but lacks the really toxic chemicals to wipe out everything. No worse than anything else available though, hence 4 star rating.
Does what it says on the label it kills weeds ... which is most impressive
