Masonry Cleaning With Abrasives

Masonry Cleaning With Abrasives
Various Cities and Counties,
California, USA

Abrasive cleaning is a generic term for abrasive media forced against the masonry surface in order to mechanically remove the soiling agent or coating. A much-abused method for the last hundred years, it has been unfairly tarred with the brush of "inappropriate" and "harsh" when in truth it was simply misapplied. When used correctly, it can be a useful and appropriate method for cleaning certain types of historic surfaces.
