Brick is a durable and attractive material used in building exteriors, interior elements, and paving. However, brick surfaces can accumulate dirt, stains, and biological growth over time, detracting from their aesthetic appeal.
Understanding the best brick cleaning techniques to avoid damage is essential for maintaining the beauty and integrity of brickwork.
This guide explores various methods to clean brick effectively, addressing common challenges and offering solutions for DIY enthusiasts and professional cleaners.
Key Takeaways
- Appropriate brick cleaning methods depend on understanding the different types of bricks and their specific vulnerabilities. Removing stains from brick surfaces, such as rust and mortar, is a common challenge that requires professional expertise to ensure the longevity and aesthetic appeal of the property. Certain types, like clay bricks, are particularly sensitive to urban pollution and improper maintenance techniques.
- Common brick contaminants such as efflorescence, organic growth, and various stains require specific treatments, which include dry brushing, applying vinegar solution for efflorescence, using surface biocides for organic growth, and specialised treatments for lime and metallic stains to safely and effectively remove them.
What Are the Most Effective Brick Cleaning Techniques?
When it comes to cleaning bricks, it’s essential to understand that different types of bricks have varying cleaning needs. The three most common brick types are clay bricks, facing bricks, and historical bricks, and each type is vulnerable to urban pollution and improper maintenance. To achieve optimal results, matching the cleaning method to the brick type and its current condition is crucial.
Abrasive cleaning methods can easily damage bricks, particularly those with “fire skin,” so choosing the cleaning process carefully is essential to avoid impact damage. For this delicate process, it’s best to rely on reliable brick cleaning services to handle your brick surfaces carefully.
Additionally, the type of brick and mortar used in the structure may react differently to various cleaning solutions. That’s why it’s crucial to choose cleaning solutions specifically designed for the particular type of brick in the structure, whether it’s standard brick or a unique brick face, to ensure the safety of the brickwork.
Manual vs Chemical Cleaning: Which is Safer for Your Brickwork?
Two main categories of cleaning brick surfaces are manual and chemical. Manual cleaning, which involves scrubbing the surface of the brick with a nylon brush and a gentle detergent solution, is often preferable for delicate brickwork.
Chemical cleaning, on the other hand, uses specialised brick cleaners that can effectively clean stubborn stains but might risk damaging the brick if not used correctly. Therefore, it’s pivotal to evaluate the safety of the cleaning method for the specific brick types to prevent potential damage to the brickwork.
Essential Safety Measures for Brick Cleaning
Safety holds paramount importance in the realm of brick cleaning. Careful consideration is crucial when using hydrochloric acid, as it is important to assess the type of stain and the condition of the brick to effectively target unwanted blemishes without damaging the integrity of the brickwork. This includes wearing protective gear and knowing how your actions can affect the surrounding area. Specific safety measures must be followed when working with hydrochloric or muriatic acid. These include:
- Pre-wetting the brickwork
- Treating small areas
- Testing small sections before the full application
- Ensuring safe handling of the acid
Due to its corrosive nature, personal protective equipment is essential when handling muriatic acid. This includes:
- Full-face protection
- A respirator
- Thick clothing
- Acid-resistant gloves
- Safety goggles
- A mask
- Rubber gloves
- A protective apron
DIY Brick Cleaning Guide to Clean Brickwork at Home
Gentle cleaning without harsh chemicals can maintain the aesthetic of brickwork. An effective DIY brick-cleaning solution involves mixing household vinegar with detergent and warm water.
This solution can effectively remove light stains and dirt accumulation when applied to the brick surface with a scrubbing brush. Scrubbing is paramount to remove mildew, grime, and efflorescence. A wire brush can be highly effective in cleaning the face of the brick without causing damage.
However, to avoid abrasion, you must choose a brush suitable for the type of brick. Combining the right detergent solution with scrubbing provides a safe and efficient way to clean exterior brick walls.
When to Call Professional Cleaning Services for Exterior Brick Walls
While DIY methods are effective for regular maintenance and light cleaning tasks, there are instances when calling professional cleaning services becomes necessary. For tougher stains, such as stubborn grime and soot, professional services are often required to ensure effective cleaning without damaging the brick surfaces. Additionally, when facing stubborn stains or extensive efflorescence, or when doing large outdoor brick cleaning, professionals brick cleaners equipped with the right tools, cleaning solutions, and expertise can ensure a thorough clean without risking damage to the brickwork.

Pressure Washing
High pressure washing can be an efficient brick cleaning technique for exterior brick walls, capable of removing dirt, grime, and even efflorescence—salt deposits that may form on the surface of the brick. However, it is important to note that high pressure washing can erode the surface and dislodge mortar, making it unsuitable for delicate cleaning tasks. Using the right pressure settings and angles is crucial to effectively clean exterior brick without causing damage. Low pressure, coupled with the appropriate cleaning solution, can clean brick surfaces thoroughly while preserving the integrity of both brick and mortar.
How to Remove Common Stains from Brick Surfaces?
1. Efflorescence and Salt Deposits
Efflorescence on brickwork surfaces can detract from the beauty of brick facades. Moisture within the brick travels to the surface, depositing salt that appears as a powdery residue. Removing these salt deposits requires brushing and applying a mild acid solution, such as vinegar diluted with water. When done correctly, this method will not damage the brickwork but restore the clean appearance of the exterior walls’ appearance.
2. Paint Stains
Removing paint from brick surfaces presents a significant challenge. Various brick cleaning techniques can be employed, from gentle scrubbing with detergent to applying a suitable paint remover based on the paint’s composition. Brick acid should be used cautiously, as it can damage the brick if not correctly applied. Professional cleaning services often provide efficient brick cleaning without harming the underlying brick and mortar.
3. Mortar and Grime
Mortar spills and grime accumulation on brick surfaces can impair the exterior look. To clean brickwork effectively, you must soften the mortar with water and then gently remove it using a chisel or a stiff brush, which is particularly effective for scrubbing away heavy mortar stains. This process, followed by washing the area with a detergent solution, can help maintain the neat appearance of exterior brick walls without causing damage to the mortar joints.
4. Stubborn Cement and Paint Removal
Muriatic acid solutions are a powerful tool for removing stubborn cement and paint residue on brick surfaces. However, to minimise the risk, it is best to apply the solution carefully and thoroughly rinse the area. Muriatic acid effectively cleans without compromising the integrity of brickwork when used appropriately.
Does High Strength Industrial Cleaner Damage the Brick Surface?
To avoid damaging the brick’s surface, testing high-strength industrial cleaners on a small and inconspicuous area of the brickwork before applying them widely is essential. While these cleaners can effectively remove tough stains and residues, they may pose a risk to the brick’s surface and do more harm than good, similar to high-pressure water blasting which can damage bricks and pointing, resulting in expensive repairs.
If you plan to use industrial cleaners as part of your maintenance routine, you need to understand their impact on various brick cleaning needs.
How to Clean Old Brickwork
Old brickwork can be challenging to clean, as over time, bricks tend to lose their shine and accumulate dirt, grime, and other contaminants. Traditional high-pressure washing methods can damage the surface and mortar joints of older brickwork, so it is essential to adopt a gentle approach to preserve the integrity and appearance of the bricks. To achieve this, mild cleaning solutions and gentle scrubbing tools should be used to prevent any damage to the brick surface. However, the process can be tedious and time-consuming. Hiring professional brick cleaning services is best if the brickwork is heavily stained or dirty.
Also, specialised brick cleaning scenarios, like historical brickwork, reclaimed bricks, or brick fireplaces, require unique techniques.
At Environ Property Services, we specialise in caring for historical brickworks. We use our innovative Thermatec system to restore the beauty and cleanliness of your bricks safely and effectively. Request an estimate today.
Alternative Techniques for Removing Cement Without Harming Mortar Joints
Cleaning cement from bricks without damaging the mortar joints demands careful technique and the right tools. Mechanical methods, such as a soft chisel or a special brick-cleaning wire brush to gently scrub, can be effective. These methods remove the cement residue by physically breaking it away from the brick surface without impairing the integral structure of the brickwork. Such gentle cleaning methods help preserve the longevity of both brick and mortar.
Natural Cleaning
Natural cleaning methods are a popular alternative to chemical-based cleaning solutions. These methods involve using gentle, non-abrasive materials to clean the brick surface. One effective natural cleaning method is soft washing, which uses a low-pressure water spray to remove dirt and grime from the brick surface.
Another natural cleaning method is steam cleaning, which uses high-temperature steam to loosen and remove stubborn stains. Natural cleaning methods are ideal for cleaning delicate or sensitive brick surfaces, such as those found on historic buildings or commercial properties. These methods not only effectively clean the brick but also help preserve its integrity and appearance.
Maintenance and Repair
Regular maintenance and repair are essential for preventing damage to brick surfaces and ensuring their longevity. This involves inspecting the brick wall regularly for signs of damage or deterioration, such as fine cracks or mortar stains. It is also important to address any issues promptly, such as repairing damaged mortar joints or removing stubborn stains. By following a regular maintenance schedule and using effective cleaning methods, you can help prevent damage to brick surfaces and maintain their visual appeal.
Additionally, working with a professional brick cleaning company like Environ Property Services can provide valuable guidance and expertise in maintaining and repairing brick surfaces, ensuring they remain in excellent condition for years to come.
Frequently Asked Questions About Brick Cleaning
How Often Should Exterior Brickwork Be Cleaned to Maintain Its Appearance?
Cleaning frequency for exterior brickwork varies depending on the environment and exposure to elements, with drier weather being optimal for such tasks. Generally, it’s advisable to clean brick surfaces every few years to prevent significant accumulation of dirt and stains. Regular inspections can help determine the right frequency, ensuring the brick facade remains attractive and well-maintained.
Can DIY Cleaning Methods Fully Remove Damp and Efflorescence from Brick?
If executed properly, DIY cleaning methods can effectively remove light dampness and efflorescence from brick surfaces. However, for tougher stains like rust, you might need to apply some elbow grease and specialised cleaning methods to avoid damaging the brickwork. For severe cases or recurring issues, it may be necessary to consult with professional cleaning services that can offer more specialised and potent solutions to ensure the complete removal of these conditions.
What Precautions Should Be Taken When Using Brick Acid for Cleaning?
When using brick acid for cleaning, several precautions are essential to safeguard the brickwork and the individual applying the treatment. Calcium carbonate forms when calcium hydroxide reacts with carbon dioxide, and understanding this chemical reaction is crucial when dealing with hydrochloric acid and lime leaching. Always wear protective gear, test the acid on a small area first, and thoroughly rinse the treated surface to neutralise the acid.
Conclusion
Proper cleaning of brickwork is intricate but ultimately fulfilling. It demands a nuanced understanding of various brick types, targeted treatments for common pollutants, and adherence to vital safety protocols. The cleaning methods must be tailored to the specific needs of your brickwork. Whether restoring aged bricks or caring for newer constructions, the correct cleaning method is essential for impeccable results.
