I don’t use chemicals on my lawn, but just learned that my wonderful daughter and son-in-law have hired a chemical lawn care company to get rid of their weeds. I’ve heard you speak about using a vinegar with 20% acidity to achieve the same end. I went to a large garden center, but they didn't have it. Please tell me where I can get 20% vinegar.
