If a side of your home doesn't get much sunlight, moss, mold or mildew can grow on the bricks. Mix a cup of bleach into a gallon of water and apply to the wall with a sponge. Use a natural or nylon-bristle scrub brush to remove the growth.
Instead of using the classic mold-killing treatment of chlorine, bleach, and water – which only kills the mold and doesn't also remove dead mold spores – you'll want to use undiluted vinegar.
White distilled vinegar is an affordable, natural solution to removing black mold. Its antibacterial acidic characteristics are exactly what you need to get the job done. Pour the undiluted vinegar into a spray bottle to apply to the area, or just go for it and pour that vinegar right onto the mold stains.

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.

Decades of carbon emissions from factories and industrial plants fill the air in cities with invisible particles which settle onto our brickwork and cause carbon stains. If you look around any major town or city, you're likely to find black stains on the brick exterior of old buildings, monuments, and statues.
Covering mold with paint is a waste of resources because the mold will continue to thrive and grow underneath. Eventually, the paint will bubble and peel off, and the mold will be exposed once again. Mold and mildew are an indication of potential moisture issues that need to be remediated before painting the surface.
Use undiluted white vinegar on hard surfaces in kitchens and baths. A bleach solution also works to kill mold. Mix one cup of bleach in a gallon of water, apply to the surface and don't rinse. Mix a 50/50 solution of ammonia and water.

While it will kill the mold, the discoloration and stains may remain and require additional scrubbing with a household cleaner. Distilled white vinegar can be used safely on most porous and non-porous surfaces.
Dissolve 1/2 cup washing soda (not baking soda) in 1 gallon of warm water. Lightly apply to the affected area and scrub with a soft-bristled brush. Rinse with clean water and buff dry. Another option for cleaning mildew is a solution of 1 cup ammonia, 1/2 cup vinegar, 1/4 baking soda and 1 gallon of water.
However, it is quite risky living in a home with visible mold since you are exposed to mold spores that can become airborne when blown around by the gush of wind from your windows or HVAC systems. If mold is left unattended, it can spread to other areas of your home causing serious health problems.
Mildew refers to certain kinds of mold or fungus. The term mildew is often used generically to refer to mold growth, usually with a flat growth habit. Molds include all species of microscopic fungi that grow in the form of multicellular filaments, called hyphae.
Mix Dawn and baking soda into a paste to clean detailed brickwork. For old brick, always try the least abrasive method and work your way up. Use a sturdy bristle brush when it comes to fireplace brick cleaning.
