Will a surface cleaner leave those overlapping lines on a brick drive way? I’ve recently power washed my regular concrete driveway with a surface cleaner and it left white lines up and down the driveway. I found out it was from over lapping (surface cleaner hitting some areas twice as opposed to just one pass all the way through). Sprayed it with some bleach and it was fine. I don’t want to spray my brick with bleach if this happens again, but will it? Or is it just more obvious on concrete?
