Perhaps this weed killing remedy might help, it kills weeds around my place and I am careful not to get it on anything else that I want to keep in the garden. I find it particularly useful to kill weeds that come up between paths.
Mix 1 cup of common salt with 4 cups of white vinegar. I heat the mixture in a pot on the stove to dissolve the salt and I find if I use it close to boiling temperature it seems to kill the weeds quicker.
