    Spray the vinegar let it dry then spray again, on a hot sunny day.
    I have even killed mature grasses along a fence line with that method. The stuff dries quickly so the second dose, does not take long.

    Do you just spray this stuff straight I would think? I guess mixing would water it down but this could be costly to the customer.

    You're right, no dilution. Vinegar is expensive. Even the store bought at 5% acid. The 10 & 20% is moreso.
    RU is a lot cheaper.
