Tips & Warnings
When you have removed the bricks, use an industrial vacuum to clean out any dirt or debris and then wash the section down with water before you do any more work in the area.
Muriatic acid can be applied to bricks to remove excess mortar from them. Soak the brick with the acid, being careful to not get the acid on the areas where you want mortar to remain.
