Meriatic acid is how the pros do it. I work caulking & masonary restoration fulltime for over a year now. I am a caulker/painter & have not done to much on the masonary side but have been in contruction for 13 yrs & most seem to use power washer from a distance. Then use pump sprayer to apply acid & scrub with brush, then rinse again with power washer from a distance. What I mean from a distance is, you don't want the power washer tip close to the brick, etching the surface.
