    I have heard that instead of using expensive chemicals to kill grass and weeds you can use vinegar with the same results. Is this true, if it is I would start using it myself.

    Lawn Freak, Ascetic acid (vinegar) at 30% minimum works great. There is nothing selective about the application and often it does not kill the roots but it kills off the green part above ground.

    The stuff on the shelf at your house is not strong enough to do much

    i never used just strait 30% ascetic acid , only the product burn out at 20% ascetic acid+other additives,

    couple things about burn out only, it is very very caustic material, if you get it on your skin it will irritate/burn it and most be washed off immediately, never get it in your eyes, can cause possible blindness. also it's so acidic that it will eat away at plastic and rubber seals in sprayers and should only be used at time of app and sprayer should be cleaned out after and left empty, never leave it in sprayer for extended periods of time unless you have some special type of sprayer that can handle acidic type products,

    when spraying don't be down wind of what your spraying. the smell of it is very strong too, makes me kind of sick on hot days when i use it, i hate the smell of it!!!!
    it does however work extremely well and fast at 1-4 and even better at 1-3 concentrations, at that concentration you only need to lightly wet foliage to get good burn down in 24hrs. think it needs higher temps to work more affective too?
    it is a very expensive product as well compared to other chem nonselectives, it works good for emerging weeds in beds but it's unprofessional to spray large weeds in beds and leave large clumps of dead material there, hand pick, so i really only use it for large areas that need total killing and can leave dead weeds, since it can't be left in sprayer, to me it only has it's usages for some situations.

    id say use extreme cation with 30% ascetic acid it is very dangerous!
    this type of maternal is no joke to work with

    I have had good results with store bought 5% acid vinegar. Spray maybe twice - after the first round dries, on some of the tougher things like grass.

    Glyphosate is cheaper however.

    Regular white vinegar off the shelf will work on some weeds and will work on a good deal more if you spike it with some lemon juice and clove oil which is essentially what Burnout II is. Smell isn't much of an issue for me with this product, the clove predominates, but not everyone has the same preferences.

    The fatty acid soaps work much better for me. They're broader spectrum AND more viscous than the vinegar so they are more likely to stay on the leaf surface and not drip off and kill adjacent plants. On the more tenacious perennials you will have to treat more than once and it can be tedious work to spot apply onto a leaf surface in the middle of an otherwise lovely lawn. Its hands and knees work so if you can't price accordingly then this might not be for you.
