Ivy suckers on brick walls

One wall of my house was covered with ivy. Another with boston ivy. These have been removed, but I have walls of brick covered with dead suckers. I know that I can use a s****er to remove them, but the area makes this very laborious. I do not want to use chemicals or brick cleaning acids. Does anyone know of a techique that will make the removal of these dead suckers easier. The walls in question have been repointed and the bricks are in good condition. thanks mike

 

Wire brush will remove most of them.
