Brick Cleaning removes dirt and harmful buildup from brick surfaces to protect the structural integrity of exterior walls, fireplaces and patios. Regular cleaning with the correct materials and methods prevents deterioration of brick and ensures a beautiful finish. Choosing the right cleaner depends on the reason for cleaning, whether it’s routine maintenance or removal of stubborn stains and grime. Some types of brick may need to be cleaned with more powerful chemicals than others, and careful application is necessary to avoid damage.

Generally, outdoor brick and masonry are more porous than indoor versions and require gentler cleaners to maintain their appearance. Efflorescence and mortar stains, in particular, can be tough to remove with only water rinses. The simplest method for cleaning brick is to thoroughly wet the surface and then apply a mild detergent or dish soap with a sponge, followed by a rinse of warm water.

Brick Cleaning Techniques That Restore Original Beauty

If the stains are caused by mildew or mold, bleach or hydrogen peroxide can be used for effective removal without harming the brick. To remove soot from a brick fireplace, a stiff-bristle brush and some baking soda or borax will also work well.

For more stubborn stains, muratic acid can be used but requires a high degree of care to avoid damaging the brick or masonry. Always test a small area of the brick to gauge efficacy and the sensitivity of the surface before applying any acid-based cleaner. Be sure to wear rubber gloves, protective eyewear and a face mask to protect yourself from splashes and fume inhalation. Also, be sure to work in a well-ventilated area to control exposure and minimize runoff from the cleaning site.
