Eradicating Ivy from rock wall

Any suggestions other than using a "pesticide" on how to rid ivy from a rock wall? I was given a recipe of white vinegar,dish soap,table salt combination to spray on the leaves-it didn't do anything. Any help on this would be greatly appreciated.
Thanks a bunch.

 

pruners and gloves. if the rock wall has pockets or areas where it has rooted then perhaps a trowel.

 

I'd say the same, a bit of elbow grease and a weighty yank. (and I don't mean a chunky American!)

 

Zing! :P
