The Complete Guide to Brickwork Cleaning

Professional Brick Cleaning, Stain Removal, Soft Washing and Maintenance

Brickwork is one of the most durable and attractive building materials used throughout the UK. From traditional red brick houses and historic properties to modern brick façades, garden walls, driveways and commercial buildings, brickwork provides strength, character and long-lasting protection.

However, despite its durability, brickwork is constantly exposed to environmental conditions that can affect its appearance and condition.

Over time, bricks can become discoloured by algae, moss, lichen, atmospheric pollution, dirt, mineral deposits and moisture-related staining.

Without appropriate maintenance, these contaminants can make brickwork appear neglected and, in some circumstances, contribute to deterioration of the brick surface and mortar joints.

At Mr Softwash, we specialise in exterior cleaning, including professional brickwork cleaning using methods selected for the type, age and condition of the masonry.

This comprehensive guide explains everything you need to know about cleaning brickwork, including the different types of bricks, common causes of staining, cleaning techniques, chemical treatments, maintenance and the benefits of professional brick cleaning.

1. What Is Brickwork Cleaning?

Brickwork cleaning is the process of removing dirt, biological growth, pollution deposits, staining and other unwanted materials from brick surfaces.

The objective is to restore the appearance of the brickwork while preserving the integrity of the bricks and mortar.

Professional brick cleaning may involve several techniques, including:

Soft washing

Low-pressure water cleaning

Controlled pressure washing

Specialist masonry cleaning solutions

Algae and moss treatments

Lichen removal

Efflorescence treatment

Targeted stain removal

Manual cleaning

Specialist conservation cleaning

The most appropriate cleaning method depends on the type of brick, the nature of the contamination and the condition of the masonry.

Not all brickwork should be cleaned using the same method.

Older, porous or weathered bricks may require a considerably gentler approach than modern engineering bricks.

At Mr Softwash, we believe effective brick cleaning starts with understanding the surface rather than simply applying high-pressure water.

2. Why Does Brickwork Become Dirty?

Brickwork is constantly exposed to the British climate.

Rainfall, humidity, airborne pollution and biological organisms gradually affect the appearance of exterior masonry.

Several factors contribute to dirty or discoloured bricks.

Algae Growth

Algae are among the most common biological contaminants found on exterior brickwork.

They thrive in damp environments, particularly on surfaces that receive limited sunlight.

Green algae frequently develop on:

North-facing walls

Shaded elevations

Garden boundary walls

Brickwork beneath trees

Areas near vegetation

Walls affected by persistent moisture

Algae can produce green, brown or dark discolouration.

Although algae growth is often primarily cosmetic, persistent moisture associated with biological growth can indicate conditions that require attention.

Professional soft washing can remove algae and treat biological contamination without relying on aggressive pressure washing.

Moss Growth

Moss commonly grows on damp brickwork, particularly where moisture accumulates.

It is frequently found on:

Garden walls

Retaining walls

Mortar joints

Brick steps

Shaded brick surfaces

Older brick structures

Moss can retain moisture against masonry surfaces.

Heavy moss growth may also contribute to deterioration where mortar joints are already weak or damaged.

Appropriate cleaning involves carefully removing excessive growth and addressing the conditions that encourage it.

Lichen Growth

Lichen is a biological growth formed through a relationship between fungi and photosynthetic organisms.

It can appear as white, grey, yellow, green or dark patches on brick surfaces.

Unlike loose surface dirt, lichen often adheres firmly to the masonry.

This makes it more difficult to remove.

Aggressive scraping or high-pressure washing can damage softer brick surfaces.

Professional cleaning may involve specialist treatments, controlled dwell times and gentle removal methods.

Some established lichen staining may require more than one treatment.

Atmospheric Pollution

Brickwork in urban environments can accumulate airborne pollutants.

Common sources include:

Vehicle exhaust emissions

Industrial pollution

Soot

Smoke

Airborne dust

General environmental deposits

These contaminants can gradually darken brickwork.

Black or grey pollution staining is particularly noticeable on lighter-coloured bricks.

Cleaning methods must be selected carefully because some deposits become embedded within the porous brick surface.

Damp and Moisture

Persistent moisture is one of the main factors contributing to brickwork discolouration.

Common causes include:

Leaking gutters

Defective downpipes

Poor drainage

Water runoff

Ground-level moisture

Shaded elevations

Defective pointing

Vegetation against walls

Cleaning can improve the appearance of affected brickwork, but it will not resolve the underlying source of moisture.

Where dampness is caused by a building defect, the defect should be investigated and repaired.

3. Understanding Different Types of Brickwork

Before cleaning brickwork, it is important to identify the type of brick.

Different bricks have different levels of porosity, hardness and resistance to cleaning.

Clay Bricks

Clay bricks are among the most common building materials used in British properties.

They are manufactured from clay and fired at high temperatures.

Their colour and durability depend on the clay composition and manufacturing process.

Clay bricks may be:

Red

Orange

Brown

Yellow

Buff

Blue

Multi-coloured

Some clay bricks are relatively hard and dense, while others are softer and more porous.

Cleaning should be based on the individual brick rather than its colour alone.

Engineering Bricks

Engineering bricks are generally manufactured to achieve high strength and low water absorption.

They are frequently used in:

Foundations

Damp-resistant construction details

Retaining structures

Areas requiring high durability

Certain decorative applications

Engineering bricks are often more resistant to water penetration than ordinary facing bricks.

However, their surface finish and mortar joints must still be considered before cleaning.

Facing Bricks

Facing bricks are designed to remain visible as part of a building's exterior appearance.

They are available in a wide range of colours, textures and finishes.

Some facing bricks have delicate or textured surfaces that can be damaged by unsuitable cleaning methods.

Excessive pressure may permanently alter their appearance.

Gentle cleaning is often preferable.

Handmade Bricks

Handmade bricks are commonly found on traditional buildings and period properties.

They may have irregular shapes, distinctive textures and variations in colour.

Many older handmade bricks are relatively soft and porous.

They can be particularly vulnerable to:

High-pressure washing

Aggressive scrubbing

Acidic cleaning products

Abrasive techniques

Excessive saturation

Cleaning historic brickwork should follow a conservation-led approach.

Reclaimed Bricks

Reclaimed bricks are frequently used in restoration projects, garden walls and traditional construction.

Their previous exposure and condition can vary considerably.

Some may already have weathered surfaces or weakened edges.

A careful inspection and small test area are essential before cleaning.

Sand-Faced and Textured Bricks

Some bricks have decorative surface finishes.

These may include sand-faced, textured, wire-cut or specially treated surfaces.

Aggressive cleaning can remove or alter the original finish.

The cleaning method should preserve the appearance and texture of the brick.

4. The Different Methods of Cleaning Brickwork

There are several recognised approaches to brick cleaning.

Each method has advantages and limitations.

The correct technique depends on the surface and the contamination being removed.

Method 1: Soft Washing Brickwork

What Is Soft Washing?

Soft washing is a cleaning method that uses relatively low-pressure application of appropriate cleaning solutions to remove or treat biological contamination.

Unlike conventional pressure washing, soft washing does not rely primarily on the force of high-pressure water.

Instead, suitable cleaning products are used to break down or control contaminants.

Soft washing is particularly useful for biological growth, including:

Green algae

Certain black biological stains

Moss

Lichen

Organic surface contamination

How Does Soft Washing Work?

A typical professional soft washing process involves:

Step 1: Surface Inspection

The brickwork is inspected to identify the type of brick, condition of mortar joints and nature of the contamination.

Step 2: Surface Preparation

Loose debris and excessive biological growth may be removed using appropriate methods.

Nearby surfaces, vegetation and sensitive materials are protected.

Step 3: Cleaning Solution Application

A suitable cleaning solution is applied using controlled, low-pressure equipment.

Step 4: Treatment Period

The product is allowed to work for the appropriate period, following its label instructions and the surface requirements.

Step 5: Rinsing or Further Treatment

Depending on the cleaning product and contamination, the brickwork may be rinsed using controlled low-pressure water or treated according to the manufacturer's instructions.

Step 6: Final Inspection

The surface is assessed to determine whether further treatment is required.

Benefits of Soft Washing Brickwork

Soft washing offers several potential advantages:

Reduced reliance on high-pressure water

Effective treatment of many biological contaminants

Lower risk of mechanical surface damage when correctly performed

Suitable for many types of exterior masonry

Can treat biological contamination within textured surfaces

May help delay biological regrowth when an appropriate residual treatment is used

However, soft washing is not suitable for every type of brick, stain or building.

The compatibility of the cleaning solution with the masonry must always be assessed.

5. Can You Pressure Wash Brickwork?

One of the most frequently asked questions about brick cleaning is:

Can bricks be cleaned with a pressure washer?

The answer is yes, some brickwork can be pressure washed, but it must be approached carefully.

Pressure washing can remove loose dirt and certain surface deposits from sound, suitable masonry.

However, excessive pressure can damage brick surfaces and mortar joints.

Potential Risks of Pressure Washing Bricks

Incorrect pressure washing can cause:

Surface erosion

Damage to mortar joints

Loss of decorative finishes

Increased surface roughness

Water penetration

Damage to soft or weathered bricks

Removal of the protective fired surface of some bricks

Older properties can be particularly vulnerable.

When Might Pressure Washing Be Suitable?

Controlled pressure washing may be appropriate for certain sound, durable brick surfaces where the masonry and mortar are in good condition.

The operator should consider:

Brick hardness

Surface condition

Mortar integrity

Water pressure

Nozzle type

Working distance

Water volume

Direction of the spray

There is no single pressure setting suitable for all brickwork.

Is Soft Washing Better Than Pressure Washing?

For biological contamination, soft washing is often preferable because it reduces the need for mechanical force.

For some non-biological deposits, controlled water cleaning or specialist masonry cleaning may be more effective.

The best cleaning method is the one that removes the contamination without damaging the brickwork.

6. How to Remove Green Algae From Bricks

Green algae are particularly common on brickwork throughout Dorset and Hampshire.

The region's relatively mild, damp climate can encourage biological growth on shaded exterior surfaces.

Why Do Bricks Turn Green?

Green discolouration commonly occurs when algae colonise damp masonry.

Contributing factors include:

Persistent moisture

Limited sunlight

Poor airflow

Nearby trees and shrubs

Rainwater runoff

Shaded walls

How Is Green Algae Removed?

Professional treatment generally involves:

Inspecting the brickwork.

Identifying the biological contamination.

Removing excessive loose growth where necessary.

Applying a suitable masonry-compatible algae treatment.

Allowing the product to work.

Rinsing or leaving the treatment in place as directed.

Reassessing the surface.

Will Algae Return?

Algae can return if environmental conditions remain favourable.

The speed of regrowth depends on factors such as moisture, shade and exposure.

Periodic maintenance and correcting sources of persistent dampness can help reduce future growth.

7. How to Remove Black Stains From Brickwork

Black staining is another common problem affecting exterior brickwork.

However, not all black stains have the same cause.

Possible sources include:

Atmospheric pollution

Soot

Biological contamination

Damp-related deposits

Carbon staining

Organic material

Metal-related staining

Identifying the cause is essential.

Black Biological Staining

Some dark biological deposits respond to appropriate biocidal cleaning treatments.

Depending on the organism and degree of staining, multiple treatments may be necessary.

Pollution and Carbon Staining

Black pollution deposits may require specialist masonry cleaning products.

Soft washing treatments designed primarily for biological contamination may not remove embedded carbon deposits.

Why Identification Matters

Using the wrong cleaning solution can produce poor results or cause damage.

For example, applying a biological cleaning product to a mineral or carbon deposit may have little effect.

Professional brick cleaning begins with identifying the contamination before selecting a treatment.

8. How to Remove Moss From Brickwork

Moss is commonly found on garden walls, retaining walls and older brick structures.

It often develops where moisture remains trapped in surface irregularities and mortar joints.

The Brick Moss Removal Process

A suitable cleaning process may include:

Initial Inspection

Check whether the moss is growing on sound brickwork or within deteriorating mortar joints.

Careful Physical Removal

Excessive moss may be removed using non-damaging tools.

Metal scrapers and aggressive wire brushing should generally be avoided on softer brick surfaces.

Biological Treatment

An appropriate treatment may be applied to control remaining moss and associated biological growth.

Surface Assessment

The brickwork is checked for remaining contamination and any maintenance issues.

Why Moss Should Be Managed

Established moss can retain moisture and conceal deteriorating mortar joints.

Removing heavy growth also improves the appearance of garden walls and external brick surfaces.

9. How to Remove Lichen From Bricks

Lichen can be particularly difficult to remove because it adheres closely to masonry surfaces.

It may form crust-like patches that remain visible after initial treatment.

Why Is Lichen Difficult to Remove?

Lichen can develop within the small surface irregularities of porous materials.

Attempting to remove it aggressively can damage the brick face.

Professional Lichen Removal

Depending on the masonry, treatment may involve:

Specialist biocidal products

Controlled application

Appropriate treatment periods

Gentle rinsing

Repeat treatments

Natural weathering following treatment

Results may develop gradually.

It is important to avoid forcing immediate removal where doing so could damage the masonry.

10. What Are White Stains on Brickwork?

White staining on brickwork is frequently caused by efflorescence.

What Is Efflorescence?

Efflorescence occurs when water transports soluble salts through masonry.

As the moisture evaporates, salts can crystallise on the surface.

This creates white or pale deposits.

What Causes Efflorescence?

Common causes include:

Moisture moving through brickwork

Soluble salts within masonry materials

Newly constructed walls

Rainwater penetration

Ground moisture

Certain construction materials

How Do You Remove Efflorescence?

Light efflorescence can sometimes be removed using a dry, soft brush.

More persistent deposits may require specialist treatment.

However, it is important to distinguish efflorescence from other white deposits, including lime staining and calcium-based deposits.

Should You Use Acid to Remove Efflorescence?

Acidic cleaning products should not be used indiscriminately.

Some bricks and mortars are sensitive to acids, which may cause discolouration, surface damage or additional staining.

Incorrect chemical treatment can make the problem worse.

Where efflorescence repeatedly returns, the underlying moisture source should be investigated.

11. How to Remove Rust Stains From Bricks

Rust staining may appear as orange, reddish-brown or dark brown marks.

Common sources include:

Metal railings

Steel fixtures

Garden furniture

Corroding fixings

Metal drainage components

Iron-containing deposits

Rust stains may penetrate porous brick surfaces.

General algae treatments are unlikely to remove established iron staining effectively.

Professional removal may require a specialist masonry-compatible rust remover.

The correct product depends on the brick composition and the nature of the stain.

A test area is essential.

12. How to Remove Cement and Mortar Stains From Bricks

Cement and mortar residues are common on newly constructed brickwork.

They may appear as:

Grey smears

Hardened mortar deposits

Cement splashes

White or pale construction marks

Removing these deposits requires care.

Aggressive scraping can scratch or chip the brick surface.

Some cement-removal products contain acids that can damage particular brick types or alter mortar joints.

The safest method depends on the brick manufacturer's recommendations, the age of the mortar and the severity of the deposits.

For new brickwork, cleaning should not begin until the masonry has reached an appropriate stage of curing.

13. Cleaning Old and Historic Brickwork

Older buildings require special consideration.

Historic brickwork may contain softer bricks and traditional lime mortar.

These materials often behave differently from modern brickwork.

Why Historic Brickwork Is Vulnerable

Older masonry may have:

Porous brick surfaces

Weathered mortar joints

Lime-based mortar

Fragile decorative features

Previous repairs

Existing moisture problems

High-pressure water cleaning can cause irreversible damage.

Recommended Approach

Historic masonry should be assessed individually.

A conservation-led cleaning process may include:

Detailed inspection

Identification of brick and mortar types

Small cleaning trials

Gentle manual techniques

Specialist low-impact cleaning

Careful moisture management

Where a building is listed or otherwise protected, appropriate permissions and conservation advice may be required.

The objective should be to preserve the building's historic character rather than make old bricks look artificially new.

14. Cleaning Brick Garden Walls

Brick garden walls are particularly vulnerable to biological contamination.

They are often exposed to:

Soil moisture

Vegetation

Shade

Rainwater runoff

Moss

Algae

Lichen

Garden walls may also have weathered mortar joints or damaged coping stones.

Professional Garden Wall Cleaning

The cleaning process should begin with an inspection of the wall's structural condition.

Loose or unstable masonry should be repaired before cleaning.

Depending on the surface, suitable treatments may include gentle manual removal, low-pressure cleaning and targeted biological treatment.

Special attention should be given to nearby plants, lawns and drainage areas.

15. Cleaning Brick Driveways and Paving

Brick driveways and block paving are exposed to different types of contamination from vertical walls.

Common problems include:

Algae

Moss

Weeds

Oil stains

Tyre marks

Dirt

Lichen

Organic debris

Cleaning methods depend on the paving material and construction.

Some brick and concrete block paving can tolerate controlled pressure washing, but excessive pressure may disturb jointing sand or damage the surface.

Brick Driveway Cleaning Process

A typical process may include:

Inspecting the paving.

Removing loose debris.

Treating biological contamination.

Cleaning using appropriate equipment.

Managing wastewater.

Allowing the surface to dry.

Replacing jointing sand where required and appropriate.

Assessing whether further treatment is needed.

Not all paving requires the same treatment.

Clay pavers, concrete blocks and natural stone should be assessed separately.

16. Cleaning Brick Patios and Pathways

Brick patios and pathways can become slippery when algae and moss develop on their surfaces.

This is particularly common in shaded gardens.

Professional cleaning can improve the appearance of the paving and remove surface contamination that contributes to slippery conditions.

The method must account for:

Surface texture

Jointing material

Drainage

Nearby vegetation

Existing damage

Type of biological growth

A suitable maintenance programme can help keep external brick paving in better condition.

17. What Chemicals Are Used to Clean Brickwork?

Professional brick cleaning may involve different categories of cleaning products.

The correct choice depends on the type of contamination and the characteristics of the masonry.

Biocidal Cleaning Products

Biocidal products are used to control biological organisms.

Depending on the product's authorised uses, these may include treatments for algae, moss and other biological growth.

Some formulations contain quaternary ammonium compounds, such as:

Benzalkonium chloride (BAC)

Didecyldimethylammonium chloride (DDAC)

These ingredients are used in certain biocidal formulations.

However, their suitability depends on the specific product, concentration, intended use and regulatory authorisation.

Products should only be used in accordance with their approved label instructions.

Sodium Hypochlorite-Based Cleaning Products

Sodium hypochlorite is used in some professional exterior cleaning formulations.

It can be effective against certain types of organic staining and biological contamination.

However, it requires careful handling and may be unsuitable for some masonry, metals, finishes and surrounding materials.

Incorrect use can cause discolouration or damage.

It should never be mixed with acids or ammonia-containing products.

Specialist Masonry Cleaners

Specialist products may be used for:

Carbon staining

Rust deposits

Cement residues

Mineral staining

Certain atmospheric deposits

The formulation must be compatible with the brick and mortar.

Are Brick Cleaning Chemicals Safe?

Safety depends on the product and how it is used.

Professional operators should follow applicable UK requirements, including COSHH assessments, product labels and safety data sheets.

Appropriate measures may include:

Personal protective equipment

Controlled application

Protection of vegetation

Prevention of chemical drift

Protection of adjacent surfaces

Appropriate wastewater management

Safe storage and handling

Chemical runoff must not be allowed to contaminate watercourses or surface-water drainage systems.

At Mr Softwash, selecting an appropriate cleaning method and protecting the surrounding environment are essential considerations in professional exterior cleaning.

18. Can Brick Cleaning Damage Mortar Joints?

Yes. Incorrect cleaning can damage mortar joints.

Mortar is an essential component of brickwork.

It helps distribute loads, accommodates movement and contributes to the wall's resistance to weather.

Older mortar may be particularly vulnerable.

Common Causes of Mortar Damage

Excessive water pressure

Aggressive brushing

Incompatible cleaning chemicals

Repeated saturation

Cleaning already deteriorated joints

If mortar is loose, cracked or missing, repairs may be necessary before cleaning.

Cleaning should never be used as a substitute for essential masonry maintenance.

19. Should You Seal Brickwork After Cleaning?

Brick sealing is sometimes recommended following cleaning.

However, sealing is not necessary or appropriate for every brick surface.

Potential Benefits of Suitable Water-Repellent Treatments

Certain breathable masonry water repellents may help reduce rainwater absorption.

This can potentially reduce moisture-related staining in appropriate circumstances.

Potential Problems With Brick Sealers

Unsuitable sealers may:

Restrict moisture evaporation

Trap existing moisture

Change the brick's appearance

Create uneven finishes

Contribute to salt-related deterioration

Complicate future maintenance

Older and traditionally constructed buildings require particular caution.

A water-repellent treatment should only be considered after assessing the brickwork, moisture conditions and manufacturer guidance.

Brickwork should not automatically be sealed simply because it has been cleaned.

20. How Often Should Brickwork Be Cleaned?

There is no universal cleaning schedule for all brickwork.

The frequency depends on:

Property location

Exposure to rainfall

Surrounding vegetation

Sunlight

Brick porosity

Moisture levels

Type of contamination

Previous maintenance

A shaded garden wall may require attention more frequently than a sunny, exposed house elevation.

Recommended Maintenance Approach

Inspect exterior brickwork periodically, particularly after prolonged wet weather.

Look for:

New algae growth

Moss accumulation

Blocked drainage

Leaking gutters

Damaged pointing

Persistent damp patches

Unusual staining

Cleaning should be carried out when necessary rather than according to an arbitrary fixed schedule.

21. DIY Brick Cleaning vs Professional Brick Cleaning

Some light surface dirt can be removed using simple maintenance techniques.

However, more established contamination may require specialist equipment and expertise.

DIY Brick Cleaning

For sound modern brickwork with light surface dirt, gentle brushing and a small amount of clean water may be sufficient.

Before cleaning:

Check the brick and mortar condition.

Test a small, inconspicuous area.

Avoid aggressive wire brushing.

Avoid excessive water pressure.

Do not use household acids or bleach mixtures.

Follow manufacturer guidance.

Protect surrounding materials.

If the brickwork is old, fragile or affected by persistent staining, professional assessment is advisable.

Professional Brick Cleaning

Professional cleaning is particularly useful for:

Large elevations

High-level brickwork

Established algae growth

Extensive lichen

Pollution staining

Difficult mineral deposits

Sensitive masonry

Commercial buildings

Professional operators can assess the contamination and select an appropriate treatment rather than relying on one cleaning method for every surface.
