Weed Be Gone/Round-up alternative

This recipe to get rid of weeds is all over the internet, we just like to have it handy which is why it is here.

Ingredients:
1 gallon white vinegar
2 cups epsom salts
1/4 cup Dawn (blue)

Combine the ingredients in a large container. Mix well. Add to spray bottle and use liberally. It needs to be reapplied often and it only kills what was directly sprayed.
