    i've had good success with Burn Out 2. like any natural non selective it takes a couple hits to fully kill it though.

    Wife cleaned out the coffee pot the other day with white vinegar. After she ran it through the coffee maker, she dumped it on the crabgrass in the sidewalk cracks. They're deader than a hammer 2 days later.

    fire or a STRONG vinegar.

    Fire being a propane type torch you can buy, there are a few threads about it if you do some research,

    The vinegar is 20% acid? I forget the correct numbers, not your vinegar in the pantry though, again there are threads about it too, just got to blow the dust off the tops of them.

    Careful with the fire. I'm not saying don't do it, but you have to be careful applying concentrated heat to concrete. :cry:

    The coffee pot treatment must have concentrated the household vinegar sufficiently, 'cause it worked like a charm.
