Brick, with its warm, inviting aesthetic, serves as a classic material in both interior and exterior home designs. 

However, maintaining its beauty requires regular care and cleaning, as brickwork can accumulate dirt, grime, and various stains over time. 

This guide provides everything you need to know about cleaning brick surfaces inside and out to restore their natural charm and ensure their longevity.

Understanding the Basics of Brick Cleaning

Why is it Essential to Clean Brick Walls?

Cleaning brick walls is essential not only for aesthetic reasons but also for the structural integrity of the brickwork. Dirt, moss, and mildew that accumulate on the surface of the brick can retain moisture, leading to damage over time. Regularly cleaning bricks helps prevent decay and keeps them looking their best, preserving the value of your home.

What Makes Bricks Get Dirty or Stained?

Bricks can get dirty and stained from a variety of sources. Exterior brick walls are exposed to the weather, leading to stains from rainwater, growth of moss and mildew, and accumulation of grime from air pollution.

Interior brick may accumulate soot, especially near fireplaces, and dust and dirt from general household activities. The type of brick and the local environment also play roles in how quickly and severely brick surfaces become stained.

The Difference Between Interior and Exterior Brick Cleaning

The primary difference in cleaning exterior versus interior brick lies in the exposure to elements and the type of soiling of each face.

Exterior brick walls contend with harsher conditions, requiring more robust methods like pressure washing for effective cleaning.

Interior brick, meanwhile, often needs gentler techniques to avoid damage to the bricks or mortar, focusing on removing soot or dust without introducing excessive moisture.

Preparing Your Bricks for Cleaning

Assess the Condition of Your Brickwork Before Cleaning

Before cleaning, closely examine the brickwork to determine its condition. Look for signs of damage or weakened mortar, which may be exacerbated by cleaning. 

Consider the age and type of brick, as historic or clay brick may require special care to prevent damage. Identifying these factors early can help you choose the most appropriate cleaning methods to protect your brickwork.

Gather the Right Tools and Materials for Brick Cleaning

For effective brick cleaning, gathering the correct tools and materials is crucial. Essential items include a bristle brush (or pressure washer for exterior brick), rubber gloves, protective eyewear, dish soap or a more potent cleaning solution like boric or muriatic acid for tougher stains, a sponge, and ample warm water. 

Always test cleaning solutions on a small area of the brick to ensure they do not cause damage.

Protect Surrounding Areas from Damage During Cleaning

When preparing to clean brick, especially exterior brick, it’s important to protect surrounding areas. Cover plants, ground, and nearby surfaces to shield them from potentially harsh cleaning solvents. 

Ensure windows are closed to prevent spray or runoff from entering your home. Taking these precautions can prevent unintended damage or additional cleaning tasks.

A Step-by-Step Guide to Cleaning Exterior Brick Surfaces

How to Remove Grime and Dirt from Exterior Brick Walls

To remove grime and dirt from exterior brick walls, start by saturating the bricks with a hose to loosen the dirt. 

Mix a simple cleaning solution of dish soap and warm water in a bucket. Using a bristle brush, scrub the brick surfaces in sections, working the soapy mixture into the bricks. Rinse thoroughly with water to prevent soap residue.

 For larger areas, consider using a pressure washer at a low setting to avoid damaging the brick.

Techniques for Tackling Tough Stains on Outdoor Brickwork

For tough stains on outdoor brickwork, such as moss or mildew, a stronger solution may be necessary.

Mixing diluted bleach with water in a spray bottle can effectively address these concerns. Spray the affected area, let the solution sit on the brick for a few minutes, then scrub with a bristle brush and rinse thoroughly.

For especially stubborn stains, muriatic acid diluted according to the manufacturer’s instructions can be used, but always with extreme caution and protective gear.

If you are dealing with paint stains, paint removal may require a specialised paint remover designed for brick surfaces. Choose the appropriate paint remover based on the type of paint, and always test in a small area first to avoid damage.

When and How to Use A Pressure Washer on Exterior Bricks

Using a pressure washer on exterior bricks is effective for removing built-up grime and stains. 

However, it should be used cautiously to avoid damaging the mortar or brick face. Always start with the lowest pressure setting, hold the washer at a distance, and use a sweeping motion. Test on a small, inconspicuous area first. 

Pressure washing once a year or as needed can keep your exterior walls looking fresh without causing harm.

Effective Methods for Cleaning Interior Brick Walls

Dealing With Soot and Grime on Indoor Brick Surfaces

To clean grime on indoor brick surfaces, a milder approach is recommended. Mix a solution of dish soap and warm water, and use a sponge to apply it gently to the surface. For a natural alternative, white vinegar can be used to clean indoor brick and remove stubborn stains or efflorescence.

For tougher stains, a paste made from salt and detergent applied with a brush can provide a deeper clean without harsh chemicals. Always finish by rinsing with a damp cloth to remove any cleaning residue.

The Best Approach to Cleaning Painted Brick Indoors

For cleaning painted brick indoors, it’s crucial to avoid damaging the paint while removing dirt. Use a mild detergent mixed with water and a soft cloth or sponge to wipe down the surface gently. 

Avoid abrasive brushes or scrubbers that could scratch or peel the paint. Regular dusting can prevent buildup and make deeper cleaning less frequently necessary.

Natural Solutions for Refreshing Your Interior Brickwork

Natural cleaning solutions, such as a vinegar and water mixture, can effectively clean interior brick without introducing harsh chemicals into your home. 

Spray the brick lightly with the solution, then use a brush to scrub the surface lightly. Rinse with a clean, damp cloth to remove any vinegar residue. 

This method is perfect for maintaining the natural look of the brick while ensuring it stays clean and fresh.

Historic Home Brick Cleaning Considerations

Special Care for Older Brickwork

Cleaning brickwork in historic homes requires a gentle touch and a thoughtful approach. Older clay brickwork, often found in period properties, is more porous and can be easily damaged by harsh chemicals or aggressive cleaning methods. Before starting any brick cleaning, carefully assess the condition of your interior brick and exterior brick walls. Look for signs of crumbling mortar, cracks, or weakened bricks—these areas need extra caution to avoid further deterioration.

For cleaning interior bricks in historic homes, opt for mild dish soap mixed with warm water and applied with a soft-bristled brush or a damp cloth. This gentle cleaning solution helps lift dirt and grime without compromising the brick’s appearance or structural integrity. Avoid using a pressure washer on exterior brick, as the force can erode the brick face or dislodge old mortar. Instead, use a stiff brush and a suitable cleaning solution, working slowly to remove surface stains and accumulated dirt.

If you’re unsure about the best approach, consult a professional with experience in historic brick cleaning and restoration.

Maintaining your interior brick: A different approach from exterior brick?

Key differences in cleaning interior vs. exterior brick walls

Interior brick walls generally require less aggressive cleaning methods compared to exterior walls due to less exposure to harsh environmental elements. 

Dusting and vacuuming can remove loose dirt from interior surfaces, and mild detergent solutions can be used for deeper cleaning without the risk of introducing excessive moisture.

Preventative measures to keep your interior brick clean and pristine

To minimize the time and effort required in cleaning interior brick, regular dusting and prompt attention to spills or stains are essential. 

Sealing interior brick with a silicone-based sealer can also provide a protective barrier against stains, making future cleaning easier and more effective.

Dealing with grime and mildew on interior bricks

In cases where grime or mildew has developed on interior brick surfaces, a solution of diluted bleach or a mildewcide product can be effective. 

Always ensure proper ventilation when using chemical cleaners indoors and test any solution on a small, inconspicuous area before full application.

Step-by-step guide on how to clean a brick wall effectively

Preparation: Tools and solutions you’ll need for the job

Before starting the cleaning process, gather all the necessary tools and solutions for brickwork cleaning. You’ll need a bucket of warm water, mild detergent or a prepared brick cleaning solution, a spray bottle for application, soft bristle brushes or scrub brushes, and protection for your hands and eyes. Also, prepare a clean water source for rinsing.

Cleaning process: Scrubbing, rinsing, and dealing with tough spots

Begin by dampening the brick surface with clean water, which helps prevent the brick from absorbing the cleaning solution too rapidly. Apply your chosen solution using a spray bottle or a soft brush, then gently scrub the surface to lift dirt and stains.

For tough spots, additional applications or a more targeted approach with a wire brush may be necessary. Rinse the area thoroughly with clean water, ensuring all soap residues are removed.

Aftercare: How to maintain clean brickwork and avoid frequent cleanings

After cleaning, taking steps to prevent rapid re-soiling can extend the time between cleanings. Apply a sealant specifically designed for brick to protect against moisture and stains. 

Regularly inspecting your brickwork for damage and addressing issues promptly can also prevent problems that could lead to more significant cleaning challenges in the future.

Frequently Asked Questions:

Q: What do I need to know about cleaning and restoring my home’s exterior brick walls?

A: Cleaning and restoring your home’s exterior brick walls involves removing dirt and grime without causing damage to the brick. It’s a delicate process that often requires specific brickwork cleaning solutions. It’s essential to choose the right ways to clean that will not harm the brick face. Gentle methods include using water to clean the brick or specific brick cleaner solutions designed for this purpose. Avoid abrasive cleaning methods that can erode or damage the brickwork.

Q: Can I use a pressure wash to clean brick walls without causing damage?

A: While using a pressure wash can be an effective way to clean the brick, it’s crucial to use it correctly to avoid damage. The high pressure can cause harm to older or more fragile bricks. It’s best to use a low-pressure setting and keep a considerable distance from the brick surface when spraying, to protect the individual bricks. Test a small, inconspicuous area first to ensure it won’t damage the brick.

Q: Are there specific cleaning solutions recommended for brick exteriors?

A: Yes, there are specific brick cleaning solutions available that are formulated to safely clean the surface without causing damage, ideal for those planning to apply brick sealant afterward. These cleaners help to remove dirt and grime effectively while protecting the brickwork. It’s also possible to make a mild cleaning solution at home using water and a small amount of detergent. Avoid using acidic cleaning solvents, as they can erode the face of the brick over time.

Q: How can I clean bricks that are particularly old or delicate?

A: For cleaning old or delicate bricks, such as old brick or engineering bricks, it’s vital to use a gentle approach. Start with the softest cleaning method possible, such as brushing with a soft-bristled brush to clean the surface or using water to spray the brick gently. If necessary, move on to a mild brick cleaner, but always test a small area first. Avoid high-pressure washing and harsh chemicals that can damage the brick face.

Q: What’s the best way to deep clean interior and exterior brick walls?

A: To deep clean interior and exterior brick walls, start by dusting or vacuuming the surface to remove loose dirt. For a deeper clean, use a mixture of water and gentle detergent, applying it with a soft brush to scrub the bricks gently. For exterior bricks, a garden hose with a gentle spray setting can be used to rinse off the solution. In the case of stubborn stains, a specialized brick cleaner may be necessary. Always rinse thoroughly with water after cleaning.

Q: How can I protect my brickwork after cleaning?

A: To protect your brickwork after cleaning, consider applying a sealant designed for brick exteriors. Applying brick sealant can help to repel water and prevent dirt and grime from adhering to the surface, making future cleaning easier. Ensure the brick is completely dry before applying any sealant, and choose a breathable product that won’t trap moisture within the brick, which could lead to damage over time.

Q: Are there any unconventional methods to keep your bricks clean and maintain their look over time?

A: Beyond conventional cleaning methods, maintaining the cleanliness of your bricks involves regular, gentle cleaning to prevent the buildup of dirt and grime. Some homeowners use diluted vinegar solutions for spot cleaning, though this should be done with caution to avoid damaging the brick. Additionally, strategically placed landscaping can help shield brick walls from excessive dirt and splashes, reducing the need for frequent cleaning.

Q: Can I clean brick exteriors with everyday household items?

A: Yes, everyday household items like diluted dish soap or vinegar can be used cautiously to clean brick exteriors. When using such items, it’s essential to thoroughly rinse the area with water afterward to prevent any potential damage to the brickwork. For tough stains, creating a paste with baking soda and water, applied with a soft brush, can be effective. Always test these methods on a small, inconspicuous area first.
