Efflorescence is primarily an appearance problem that occurs with masonry and often plaster. Rarely do these deposits of crystalline salts do any harm to masonry surfaces. In most cases, the efflorescence appears as a white dust or deposit on the surface of brick walls, chimneys or patio bricks. In certain cases, the color of these salts can also be green and brown. While it's difficult to control, efflorescence can be prevented by reducing moisture sources.
The following publications have excellent information concerning what is efflorescence, its prevention and guidance on efflorescence removers. Some of them may be available at your local library.
