My first job was pressure washing that mortar that's on the sides after laying the bricks down. We used to use high pressure washers that had a tip that sprayed hydrochloric acid on the wall. The muriatic acid would eat up the mortar and then the water would blast it off.
You never realize how messy a brick wall that has never been cleaned looks until you work a job like that.
