Bleach will just kill the leafs not the root and it'll come back.

I know diluted white vinegar works on some weeds, I think you have to use it when ist not going to rain and works best when its sunny

Roundup also kills weeds I used it yesterday on driveway and weeds died today left a slight white stain which washes off
