How To Clean BricksBeautiful masonry is occasionally marred by improper cleaning, which can be avoided. The purpose of cleaning new masonry is to remove excess mortar from the face of the brick. The sooner the brickwork is cleaned after installation, the easier it is to remove the mortar smears. The easiest cleaning is accomplished shortly after laying, usually the same day, by wiping off the excess mortar using a bristle brush. The second easiest method is to wash down the wall the same or following day with only water and a brush. The third approach is to use chemical cleaners. The chemicals typically contain some form of acid for softening the mortar. These chemicals, while softening the mortar smears, can discolor the mortar and the brick and bring salts to the surface if improperly used. Hanson Brick recommends using Prosoco* or other professional/ proprietary cleaning products.
