Vinegar is a safe and effective mold removal solution, but if this method doesn't prove to be effective, then a heavier-duty weapon may be deployed: bleach. One cup of bleach mixed with a gallon of water should do the trick.
Use a Pressure Washer
If you have a small amount of mold or algae, you may find that the first two steps of drying out and sweeping the area is enough to remove it. If this is not the case, pressure washing is often quite effective in removing mold and algae from pavers, bricks or concrete.
A mixture of one part bleach with three parts water is the most common cleaning agent used to remove mold from pavers.
The mold on pavers problem occurs when algae and/or mold and other fungal types grow on damp or moisture-laden pavers. The answer is to eliminate the presence of moisture from underneath. Without moisture, the algae/mold cannot survive.
Whilst vinegar will not directly dissolve concrete itself, but it will degrade the cement that binds your concrete slabs or flags together. Extended exposure to vinegar will also cause any polish or sealant on your pavers to erode over time, leading to bleaching, stains and weathering.
Cleaning your pavers with bleach has a lot of benefits: Disinfecting the Surface: Bleach is an effective disinfectant and can kill any bacteria or mold on the surface. This will help to prevent any health hazards from occurring. Removing Tough Stains: Bleach is also effective in removing tough stains from the surface.
While it is possible to use bleach to kill mold as well, experts agree that vinegar is a much better option. Unlike bleach, vinegar can effectively kill the mold at the root, which means it's less likely to return. Vinegar is also less toxic than bleach, making it a better choice for household use.
For a natural solution for getting rid of black mold, combine one part baking soda with five parts distilled white vinegar and five parts water in a spray bottle. Alternatively, you can use a chemical-based mold and mildew remover, all-purpose cleaners, bleach or dish soap.
White vinegar is a mildly acidic product that cleans, deodorizes, and disinfects. It can also kill 82% of mold species, including black mold, on porous and non-porous surfaces. You can use it safely on most surfaces, and its offensive odor goes away quickly. Pour undiluted white vinegar into a spray bottle.
Removal of Cinder Block Mold
The U.S. Environmental Protection Agency, or EPA, recommends that homeowners use liquid dish detergent and water to remove mold. A cleaning solution of chlorine bleach and water will also kill mold.
Cleaning brick pavers

In a study testing the effects of various mold-killers, hydrogen peroxide was found to be moderately effective at killing mold on nonporous surfaces, albeit less potently than bleach.
Vinegar can kill black mold and is best used on nonporous surfaces. White vinegar is a powerhouse for cleaning, deodorizing, and disinfecting around the house. It can also kill black mold, a mold that commonly appears when there is water damage. Spray vinegar onto the moldy surface and leave it for an hour.

This will tell you if you can clean the mold yourself, or if it's reached a point where you need to bring in the pros. If the outbreak is less than 10 square feet, the EPA says it's safe to handle the cleanup yourself (FEMA sets the limit at 25 square feet, so there's some wiggle room).
There are useful tools for cleaning paving stones, such as joint scrapers, sweepers, and pressure washers. In addition, pavers can be cleaned with a small pickaxe, broom, and garden hose.
To clean paver slabs, you can use a detergent, such as Dawn, or a vinegar-water solution that is gentle enough to effectively clean without causing damage to your concrete pavers.
On the other hand, baking soda is useful because it is slightly abrasive, which is excellent for the rough surfaces of paving slabs. When it is mixed with water, it can dissolve dirt and grease, and like vinegar, you'll only need a brush or broom when cleaning.
OxiClean is a powerful concrete cleaner that works well on various materials, including pavement and grout. This concentrated solution provides excellent cleaning without leaving residue.
Although bleach is great at the whitening effect, you can use peroxide to achieve this. Hydrogen peroxide is an oxygenated bleach. It is safe for plants, so when you rinse this solution, it won't harm anything. It works together with the dish soap and baking soda to remove dirt and whiten dirty concrete.
