Act as an acid, just burn the top. Don't kill the weed!
on 18 May 2017
Did not work for me at all. Tried multiple times in my garden and patio. It' just burns the top of weed and unwanted plants just like an acid. Do not kill the root, within days weed leafs regrows.
If you use it on the patio, make sure to do it very carefully, as it leaves white smudges all over if you aren't very precise, which don't go away without a proper wash.
