Here's what I use, Ben: Take a spray bottle and cover the bottom with salt and fill it up with vinegar. Add a few drops of dish soap and shake. Spray on the weeds.
I have never cleaned a weed before.
Boiling water. Epsom salt followed by boiling water. Plain old white vinegar. Method depends on location of weeds.
1gal.vinegar 1gal lemon juice,2 cups salt mix well spray on weeds in direct hot sun, kills 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
