I did two rounds of spraying 30% vinegar with a little soap and everything but the biggest weeds turned brown and crispy. Picture is after the first spray. Everything still green got hit in the second spray. We are going to let him back out tomorrow, fingers crossed.

The 30% vinegar, where does one get this? Is it just plain white vinegar?
I buy it at Tractor Supply. Seen it at Lowe’s and other home and garden type places as well. It is called concentrated vinegar or gardening vinegar.

General household vinegar is 5% acetic acid. The type mentioned here is 30% acetic acid. You can get it various places, mentioned above and online
as stated above, hortucultural or agricultural vinegar. I have not seen it in the store, but I was not looking for it either. If you just need a little bit, in ethnic grocery stores (the mom and pop mexican places, usually) usually carry vinegar ‘essence’, concentrated vinegar, I think around 25% strength. my mom has been using that to kill weeds in the pavement.
5% (I read canning vinegar is even 6%, but can’t conform, FB tells ya a lot of bull pockey) might work a little but should not be very effective.
That is indeed bull pockey 
Safe tested canning and pickling recipes all call for 5% vinegar. Most grocery store vinegars are 5% but you do want to check to be sure. There was a huge conspiracy scare across FB about how big vinegar wanted to ruin all your canning with lower acid vinegar but it’s not that big of an issue across brands

Yeah, like a couple of years ago somebody suggested to put eggs in socks and hang them up in a nursery to capture carbon (CO1 or 2 - regardless, such stupidity)
It is not in the literature, but spoiled eggs do explode with a loud pop and big stink!
(don’t ask how come I know)

Ohhhhh I also know! 
A friend had a habit of letting her chickens set on eggs for random amounts of time and then giving them to me to incubate, I learned to candle daily until I started refusing to set eggs for her…

my DH set a boxwood ablaze while he was using one of those flame thrower, weed killer, propane torches. He was doing the weeds in the cracks of our driveway and the hot end hit a dead part of the boxwood. BAAAMM! It went up like a roman candle!
He only uses the flame thrower to do some sort of Japanese wood treatment now … and very safely.
PS Vinegar solutions kill everything. The good and the bad and it does not breakdown as quickly and if it runs into streams/creeks it kills and knocks the ecosystem out of wack. Its actually safer to use proper weed killer that breaksdown quicker.
@alfonsina I would love to hear how Torched works out for you. I am over run with invasive plants choking out my woods, I can’t keep on top of them. I may lean into some chemical warfare this summer.
