How to Clean Brick

Brick is a beautiful and durable material that can add character and warmth to both indoor and outdoor spaces. However, over time, brick surfaces can become stained, discolored, or covered in grime, diminishing their original beauty. Whether you're dealing with a brick fireplace, exterior walls, or indoor surfaces, proper cleaning is essential to maintain the longevity and aesthetic appeal of your brickwork.


Key Takeaways

  • If pressure washing exterior brick, start with the lowest pressure setting and slowly increase as needed.

  • For heavy buildup on your brick, consider using a brick cleaner or acid wash.

  • For indoor brick surfaces, a mild cleaning solution made from warm water and a gentle detergent or dish soap is usually sufficient

  • JMS’s services include brick pinning, masonry cleaning, historical brick and mortar restoration, removal of graffiti, brick replacement, and brick and mortar repair.


How to Clean Brick Exterior


Exterior brick surfaces are exposed to various environmental elements, such as rain, sun, and pollutants, which can lead to discoloration, staining, and the growth of mold or mildew. Follow these steps to keep your brick looking fresh and clean:


Inspect and Prepare


Begin by inspecting the brick surface for any loose or damaged areas. Repair any cracks or holes before proceeding with the cleaning process. Additionally, cover any nearby plants or surfaces you don't want to get wet or exposed to the cleaning solution.

Use a Pressure Washer (with caution)


While pressure washing can be an effective method for cleaning brick exteriors, it's important to exercise caution. Using too high of a pressure can damage the brick surface or the mortar joints, potentially leading to costly repairs.


If you decide to pressure wash your brick, start with a low pressure setting and increase gradually if needed. Keep the nozzle at least 6 inches away from the brick surface and move it in a sweeping motion to avoid concentrating the water stream on one area for too long.


It's generally recommended to hire a professional pressure washing service, as they have the expertise and equipment to safely and effectively clean your brick surfaces without causing any damage.


Apply a Brick Cleaner or Acid Wash


For stubborn stains or heavy buildup, you may need to use a specialized brick cleaner or an acid wash solution. Follow the product's instructions carefully and test on a small, inconspicuous area first to ensure it doesn't cause any unwanted discoloration or damage.


How to Clean Brick Fireplace


A brick fireplace can be a stunning focal point in any room, but it's also susceptible to soot, smoke, and ash buildup. Regular cleaning is crucial to keep your fireplace looking its best. Here's how you can tackle this task:


Use a Dry Brush


Start by using a dry, stiff-bristled brush to remove any loose debris or soot from the brick surface. This initial step will help prevent spreading the grime further during the cleaning process.

Next, apply a specialized brick cleaner or a mild detergent solution to the brick surface. Follow the product's instructions carefully and allow it to sit for the recommended time. Avoid using harsh chemicals or acidic cleaners, as they can damage the brick's surface.


Scrub and Rinse


After the recommended dwell time, use a stiff-bristled brush or a non-abrasive scrub pad to gently scrub the bricks. Work in small sections and rinse thoroughly with clean water to remove any remaining cleaner or residue.


How to Clean Interior Brick Walls and Floors


Indoor brick walls may not require as intensive cleaning as exterior bricks, but they can still accumulate dust, grime, and stains over time. Here's how to keep them looking their best:


Vacuum, Sweep, and Dust


Start by vacuuming, sweeping, or dusting the brick surface to remove any loose dirt or debris. This will make the cleaning process more effective and prevent spreading the grime further.


Mix a Mild Cleaning Solution


For indoor brick surfaces, a mild cleaning solution made from warm water and a gentle detergent or dish soap is usually sufficient. Avoid using harsh chemicals or abrasive cleaners that could damage the brick's surface.


Scrub and Rinse


Use a soft-bristled brush or a non-abrasive sponge to gently scrub the brick surface with the cleaning solution. Rinse thoroughly with clean water and dry the area with a clean cloth or towel.
