Just mixed a batch of this up two days ago. Gallon of vinegar, 1 cup of salt and 1 tablespoon of Dawn. Mix the salt and vinegar and add Dawn. Pour into sprayer and spray in full sun light. This works with the sun to dry the weeds out.
Combine ingredients in a spray bottle and treat weeds at the sunniest time of day for best results.
Do not use these recipes on lawn or garden. Will kill everything.
This is the most effective all-natural weed killer DIY that we use. It's even been featured on Hometalk! Hope this helps! Hugs, Holly
