When you want to kill weeds in garden what type of vinegar do you use?

Either one will work but as a caution it will kill your plants to.

They all work. Get the cheapest kind.

I only use straight "Pickling Vinegar" - it's cheap and stronger than regular vinegar and easily found at the grocery store. I don't use Dawn or any other ingredient as the Vinegar does the job all on its own. I keep a dollar-store plant mister filled and once a week go around the garden checking for weeds. Try to avoid spraying the flowers and lawn. The best time to do this is on a sunny hot day - because it's the combination of the vinegar and hot sun that burns the weeds. One further note: if a weed has already grown a few large leaves (shading the base of the weed), I try to pull them off - as much as possible - so that the vinegar reaches the base (or root area) of the weed.

Thanks to all who replied. Will follow with advice and wait for the next hot summer day to drop the bomb! I recently uprooted 7 privacy bushes and now have a bare area of dirt and already have weeds; and I have not planted any new shrubs or flowers in this area. Would like to start anew next spring but in the interim want to prepare the soil for healthier growing with new a garden bed.

I use white vinegar with dawn and Epsom salt. Burns those little buggers right out on a hot summer day.

I buy white vinegar - 2 gallons for $4 at Sam's Club or "cleaning vinegar" for $4 a gallon. White vinegar is my go to for so many things - laundry, cleaning, weed killing - and of course cooking!

Any vinegar will work, use what is cheap. For killing weeds, I use it straight from the jug.

White vinegar and apple cider vinegar is 5% acidity

Cleaning vinegar is 6% acidity, yes 1% makes a difference

Agricultural vinegar is 10-20% acidity
