'Spalling' refers to the breakdown of bricks such as cracking, peeling, crumbling or chipping, which eventually lead to the surface of bricks breaking away from the main body. The result is that the softer portions of the brick are left exposed to the elements, which can lead to further damage.
Scrubbing With Bleach
If you have stubborn stains on your brick but don't have a power washer, you can try scrubbing. Simply mix a 10% solution of chlorine bleach to water in a bucket. Scrub the area with a stiff-bristle brush. Once you remove the stains, rinse the brick thoroughly with clean water.

Bricks turn white when this water evaporates, leaving salt deposits on the brick face. This process is known as efflorescence and is a common problem. Every time this process repeats itself, another layer of salt will form. This is why some older bricks have a thick, fluffy white layer that can be harder to remove.
If you don't have the supplies for the ammonia mixture, you can also use bleach or hydrogen peroxide to remove mold, mildew, and stains. Remove dirt and debris using the broom. Put on safety gear. Pour ½ cup of bleach or hydrogen peroxide in a spray bottle with 3 cups of water.

Staining is a cosmetic problem, but staining in your masonry may also indicate that structural water damage is not far behind.
Checks or cracks
Random crack occurs on different brick surface. It is due to the presence of lumps of lime or excess water. If lump of lime is in excess, when bricks come in contact with water, lumps of lime absorbs water causing expansion and disintegration of brick.
Efflorescence starts with salt. Salts are found in the ground and in construction materials such as brick, mortar, cement, lime, sand, clay, admixtures, and backing materials. Typical efflorescence is white but can vary in color, including yellow or brown, depending on the salt and accompanying chemicals.
