Step #3: Use Vinegar
Let the vinegar sit for about 5 minutes then scrub it off using a stiff-bristled brush. Then rinse the vinegar with hot water and spray the area again. This time, you don't need to rinse away the vinegar; leave it to let it penetrate the brick and kill the mold that's on the interior.
Cleaning bricks with vinegar is an effective and natural way to remove dirt and stains. However, it is essential to follow proper techniques to ensure the brick surface's safety and achieve the best possible results.
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.

Liquid detergent acts as an air-entraining admixture. During mixing, the detergent forms tiny air bubbles that are distributed throughout the mortar. These air bubbles lubricate the mortar, making it workable for long periods, even as the water evaporates.
You need to scrub the dirty bricks with a mixture of table salt and dish soap. The spreadable paste will work well if you are using a bristle brush. Once you have removed the paste with a washcloth, go on and use a sealant to keep the bricks in tip-top condition.
