Vinegar kills weeds?

This is so not about furniture, but I like to share my Eco tips that I have been doing for years.
I hate those ugly sharp broad leaf weeds. I also hate using toxic spray to kill them. So after a little research figured out regular cheap vinegar kills them! I'm Sure my neighbors think I'm crazy when I'm outside pouring it on my weeds, But it works... I buy the gallon size at local Sam's club. It is only a few bucks and Eco friendly!!
