I just seen an ad on TV tonight, for a 'organic' plant killer to use on hard surfaces, like walkways etc.. The ad says is made from acetic acid, and citrus acid.. (Vinegar & Lemon Juice?) .. Being the cheapy I am, I took a little vinegar outside, and poured it on a couple of weeds.. I guess I'll know tomorrow if it works or not..:rolleyes:

grasses and weeds are like animals in one respect, they got to breathe, spray them with any liquid and they will die if the liquid are not wash off of them, provide the liquid are thick enough to stay on the surface instead of running off
