Review on 🧴 Powerful 20% White Vinegar Concentrate - 1 Quart Industrial Grade for Safe and Versatile Cleaning by Jeff Kersey

They have to be transferred to a clean spray bottle first. Then I carefully sprayed all the weeds on my front steps. A week later, the seeds were scattering around the corners of my stairs, which I no longer use. After a week most of the weeds died BUT NOT ALL! Weeds had grown on the three steps that never died. I made sure every weed patch was fully sprayed (every corner of every step). That means some weeds are resistant to 20% vinegar, which was never mentioned in the product description. Also, I used 90% of a SMALL BOTTLE at once. This is financially unsustainable and not all weeds have been eradicated.
