How to Clean White Efflorescence from Concrete
Efflorescence is a white deposit of water-soluble salts that can appear on masonry bricks. It can be a fine powdery substance or a crystallized buildup. Depending on the type of salts present it can also appear green, brown, or yellow. Efflorescence happens when soluble alkalis are present in the brick or grout and moisture is able to penetrate the brick forcing salt deposits to the surface. This can happen a month after the brick was laid or as long as a year later.
