I tried it with Wally salt. Proper mix is 1-2 mix. I mixed 7 cartons (26 oz. Each) into 16 gallons of water. That’s an over mix. I have a very long driveway. I sprayed heavy. Weeds laughed at me. Mixed large scoop salt in 1 gallon water and poured heavy on small patch of weeds. Nothing…..Great value table salt from Walmart.
