What Is Professional Decking Cleaning?

Professional decking cleaning is the process of removing accumulated dirt, algae, moss, lichen and other contaminants from decking surfaces using appropriate cleaning products, equipment and techniques.

Over time, outdoor decking becomes exposed to environmental conditions that encourage biological growth.

Common problems include:

Green algae growing across decking boards

Black organic staining

Moss accumulating between boards

Slippery decking during wet weather

Dirt and grime becoming embedded in the surface

Weathered or discoloured timber

Organic growth around decking joints

Staining from leaves and surrounding vegetation

Professional cleaning helps remove these contaminants and improve the appearance and usability of outdoor decking.

The most suitable cleaning method depends on the decking material, its condition and the type of contamination present.

At Mr Softwash, we assess these factors before recommending a cleaning treatment.

Why Does Decking Become Green and Slippery?

One of the most common decking problems experienced by homeowners in Dorset and Hampshire is green, slippery decking.

This is usually caused by algae and other biological growth developing on damp surfaces.

1. Algae Growth

Algae thrive in damp environments, particularly where decking receives limited sunlight.

Green algae can spread across decking boards, creating an unattractive surface that may become slippery when wet.

Decking positioned beneath trees, beside fences or in shaded gardens is particularly susceptible.

2. Moss Growth

Moss commonly develops between decking boards and around areas where moisture accumulates.

If left untreated, moss can spread and contribute to moisture retention.

3. Damp Weather Conditions

The relatively mild, damp climate experienced across Dorset and Hampshire can encourage algae and moss growth.

Frequent rainfall, shaded gardens and poor airflow can all contribute to prolonged surface moisture.

4. Dirt and Organic Debris

Leaves, soil, pollen and other organic materials can accumulate on decking.

As these materials decompose, they can create conditions that support biological growth.

5. Poor Drainage

Decking that does not drain efficiently may remain damp for extended periods.

Standing water and trapped moisture can encourage algae and moss to develop.

Can Slippery Decking Be Cleaned?

Yes.

Professional decking cleaning can remove much of the algae, moss and surface contamination responsible for slippery decking.

However, cleaning cannot guarantee that decking will remain slip-free, particularly during wet or icy conditions.

Regular maintenance and suitable slip-resistant measures may also be necessary.

Our Professional Decking Cleaning Methods

At Mr Softwash, we recognise that different decking materials require different cleaning techniques.

Wooden decking, composite decking and PVC decking can respond differently to water pressure and cleaning products.

Using an unsuitable method can cause damage.

We therefore select cleaning methods according to the material, condition and manufacturer's recommendations.

1. Soft Washing Decking

Soft washing is a low-pressure exterior cleaning method that uses suitable cleaning solutions to help remove organic contamination.

It can be particularly useful for decking affected by algae and other biological growth.

Benefits of Soft Washing Decking

Uses low water pressure

Helps remove algae and organic contamination

Can reduce the need for aggressive mechanical cleaning

Suitable for certain sensitive surfaces

Can improve the appearance of weathered decking

May provide a gentler alternative to high-pressure washing

Soft washing treatments must be compatible with the decking material.

Some timber treatments, composite surfaces and surrounding materials can be affected by unsuitable chemicals.

Mr Softwash selects treatments based on the surface being cleaned and follows appropriate application, rinsing and environmental precautions.

2. Controlled Pressure Washing

Pressure washing can be effective for removing dirt and grime from certain decking surfaces.

However, excessive pressure can damage timber fibres, create splintering, leave visible cleaning marks or affect the finish of composite decking.

For this reason, high-pressure washing is not automatically the best choice.

Where pressure washing is appropriate, we consider:

Decking material

Surface condition

Manufacturer's cleaning instructions

Water pressure

Nozzle selection

Cleaning distance

Direction of the timber grain

Existing coatings and finishes

Some decking surfaces are better cleaned using low-pressure methods rather than conventional pressure washing.

3. Manual Decking Cleaning

Certain areas may require brushing or manual cleaning.

This can include:

Decking edges

Steps

Corners

Areas around balustrades

Spaces between boards

Heavily contaminated sections

Manual cleaning can be combined with other methods to achieve a more consistent result.

Wooden Decking Cleaning

Professional Cleaning for Timber Decking

Wooden decking remains a popular choice for gardens and outdoor entertaining areas.

However, natural timber is vulnerable to weathering, moisture absorption and biological growth.

Over time, wooden decking can become grey, green, stained or discoloured.

At Mr Softwash, we provide wooden decking cleaning services designed to remove surface contamination while protecting the timber wherever reasonably possible.

Common Wooden Decking Problems

Wooden decking may suffer from:

Green algae

Moss growth

Black organic staining

Surface dirt

Weathering

Uneven discolouration

Slippery surfaces

Accumulated debris

Can Wooden Decking Be Pressure Washed?

Some wooden decking can be pressure washed using carefully controlled equipment and techniques.

However, excessive water pressure can damage the wood.

Potential problems include:

Raised timber fibres

Splintering

Surface erosion

Visible pressure-washing marks

Damage to existing coatings

Water being forced into vulnerable joints

For delicate or weathered timber, gentler cleaning methods may be preferable.

Mr Softwash assesses the decking before selecting the most appropriate approach.

Types of Wooden Decking We Can Assess for Cleaning

These include:

Softwood decking

Commonly manufactured from pressure-treated pine or other softwoods.

Softwood decking can be vulnerable to damage from excessive pressure and abrasive cleaning.

Hardwood decking

Hardwood decking may include species such as iroko, balau and other durable timbers.

Although many hardwoods are naturally dense, their finishes and surfaces still require appropriate care.

Grooved wooden decking

Grooved decking can accumulate dirt and algae within its channels.

Careful brushing and cleaning may be required to remove contamination from these areas.

Smooth wooden decking

Smooth timber decking can be cleaned using suitable methods that take account of the timber's condition and existing finish.

Composite Decking Cleaning

Specialist Cleaning for Composite Decking

Composite decking is commonly manufactured using a combination of wood fibres, plastics or other engineered materials.

It is often marketed as a low-maintenance alternative to natural timber.

However, low maintenance does not mean maintenance-free.

Composite decking can still accumulate dirt, algae, pollen, grease and other surface contamination.

At Mr Softwash, we offer cleaning assessments for composite decking, with methods selected according to the product manufacturer's instructions.

Common Composite Decking Problems

Composite decking may develop:

Green algae

Surface dirt

Organic staining

Leaf marks

Grease and food stains

Pollen deposits

General weather-related discolouration

Can Composite Decking Be Pressure Washed?

This depends on the manufacturer and the type of composite decking.

Some composite decking products permit pressure washing within specified limits.

Others recommend gentle brushing, mild detergent and low-pressure rinsing.

Using excessive pressure may damage protective surface layers or leave permanent marks.

Mr Softwash does not recommend aggressive pressure washing of composite decking without first checking the manufacturer's cleaning guidance.

Capped and Uncapped Composite Decking

Different composite products have different cleaning requirements.

Capped composite decking has a protective outer layer that may be damaged by abrasive cleaning or unsuitable chemicals.

Uncapped composite decking can have different moisture absorption and staining characteristics.

Both require appropriate cleaning products and techniques.

How We Clean Decking – Our Professional Cleaning Process

At Mr Softwash, we follow a structured cleaning approach designed around the condition and material of each decking installation.

Step 1 – Decking Inspection

We begin by assessing the decking surface.

This includes identifying:

Decking material

General surface condition

Existing coatings

Algae and moss growth

Dirt and staining

Loose or damaged boards

Surrounding plants and landscaping

Drainage and access considerations

This assessment helps determine the most appropriate cleaning method.

Step 2 – Preparation

Before cleaning, we consider surrounding surfaces, furniture, plants and drainage.

Loose debris may be removed, and vulnerable areas protected where necessary.

Any significant structural defects should be addressed before cleaning.

Step 3 – Application of Suitable Cleaning Products

Where appropriate, a compatible cleaning solution may be applied to help loosen dirt or treat organic contamination.

Product selection depends on the decking material and the manufacturer's recommendations.

Cleaning chemicals are used according to their instructions, including relevant dilution, dwell-time and rinsing requirements.

Step 4 – Gentle Cleaning

The decking is cleaned using a suitable combination of low-pressure rinsing, brushing or controlled pressure washing.

Our aim is to remove contamination without unnecessarily damaging the decking surface.

Step 5 – Rinsing

Where required, the decking is rinsed to remove loosened dirt and cleaning residues.

Particular care is taken around sensitive materials and surrounding landscaping.

Step 6 – Final Inspection

Once cleaning is complete, we inspect the decking and identify any areas requiring additional attention.

Some permanent staining, timber weathering or previous surface damage may remain visible after cleaning.

Step 7 – Maintenance Advice

We can provide practical guidance on keeping decking cleaner for longer.

This may include recommendations for regular sweeping, improving drainage and reducing prolonged moisture exposure.

Decking Algae Removal

How to Remove Green Algae From Decking

Green algae is one of the most common causes of dirty and slippery decking.

Algae can develop on both wooden and composite decking, particularly in damp or shaded locations.

Professional algae removal may involve a suitable cleaning treatment combined with gentle mechanical cleaning or rinsing.

Why Remove Algae From Decking?

Removing algae can help:

Improve the appearance of decking

Reduce algae-related slipperiness

Remove unwanted biological growth

Make routine maintenance easier

Restore a cleaner outdoor living space

Algae can return when environmental conditions remain favourable.

Regular maintenance is therefore important.

Does Soft Washing Remove Algae From Decking?

Suitable soft washing treatments can help remove algae from compatible decking surfaces.

However, not every soft washing chemical is suitable for every type of decking.

The correct treatment depends on the material, finish and manufacturer's guidance.

Decking Moss Removal

Moss frequently grows between decking boards, particularly in shaded gardens.

It can trap moisture and contribute to a slippery surface.

Professional decking moss removal may involve careful brushing, debris removal and suitable cleaning treatments.

Excessive scraping or aggressive pressure washing should be avoided where these methods could damage the decking.

How Can You Prevent Moss Growing on Decking?

Although moss growth cannot always be prevented, the following steps may help:

Sweep decking regularly.

Remove fallen leaves and organic debris.

Keep gaps between boards clear where accessible.

Improve drainage where possible.

Reduce excessive shade where practical.

Avoid leaving damp objects on decking for extended periods.

Arrange periodic professional cleaning when necessary.

Black Stains on Decking – What Causes Them?

Black marks on decking can have several causes.

These include:

Organic contamination

Mould or mildew

Dirt accumulation

Tannin reactions

Metal staining

Weathering

Previous coating deterioration

Not all black staining can be removed using the same cleaning method.

For example, black staining caused by a chemical reaction between iron and timber tannins may require a different treatment from ordinary algae or dirt.

Identifying the cause of the staining is important before choosing a cleaning product.

At Mr Softwash, we assess visible staining before recommending a cleaning approach.

Soft Washing vs Pressure Washing Decking

Which Cleaning Method Is Better?

Both soft washing and pressure washing can have a role in professional decking cleaning.

However, the most suitable method depends on the surface.

Feature

Soft Washing

Pressure Washing

Water pressure

Low

Variable, potentially high

Main cleaning action

Suitable cleaning solutions and gentle rinsing

Mechanical removal using water

Algae removal

Effective with compatible treatments

Can remove surface growth

Timber damage risk

Generally lower pressure-related risk

Higher if excessive pressure is used

Composite decking

Product compatibility must be checked

Manufacturer's limits must be followed

Chemical use

Usually involves cleaning solutions

May be used with or without chemicals

Best application

Compatible surfaces affected by organic growth

Suitable robust surfaces requiring mechanical cleaning

Our Approach

Mr Softwash does not use one cleaning method for every decking surface.

Instead, we select the approach most appropriate for the material and condition.

The objective is effective cleaning without unnecessary surface damage.

How Often Should Decking Be Cleaned?

The ideal cleaning frequency depends on several factors.

These include:

Decking material

Location

Exposure to sunlight

Surrounding trees

Drainage

Foot traffic

Local weather conditions

Existing surface coatings

As a general guide, many decking areas benefit from a thorough clean approximately once a year, although some may require more frequent attention.

Decking beneath trees or in shaded, damp gardens may need additional maintenance.

Regular sweeping and debris removal between professional cleans can help reduce contamination.

When Is the Best Time to Clean Decking?

Decking can be cleaned at different times of the year, provided weather and surface conditions are suitable.

Spring Decking Cleaning

Spring is a popular time to clean decking.

Removing winter algae, moss and dirt can help prepare outdoor spaces for warmer weather.

Summer Decking Cleaning

Summer cleaning can improve the appearance of decking used for entertaining and outdoor living.

However, very hot conditions may affect how quickly cleaning products dry.

Autumn Decking Cleaning

Autumn cleaning can help remove fallen leaves, dirt and organic debris before winter.

Keeping drainage channels clear can also help reduce moisture retention.

Winter Decking Cleaning

Winter cleaning may be possible during suitable weather.

However, freezing temperatures, icy surfaces and poor drying conditions can make cleaning inappropriate.

How Much Does Professional Decking Cleaning Cost?

The cost of professional decking cleaning depends on the size, material, condition and accessibility of the decking.

Factors affecting the price include:

Decking Size

Larger decking areas generally require more cleaning time and materials.

Decking Material

Wooden, composite and specialist decking products may require different cleaning methods.

Level of Contamination

Heavily contaminated decking may need additional treatment or manual cleaning.

Accessibility

Restricted access, raised decking and difficult working conditions can affect cleaning costs.

Additional Treatments

Specialist stain removal or additional cleaning treatments may increase the overall cost.

Decking Cleaning Frequently Asked Questions

What is the best way to clean decking?

The best cleaning method depends on the decking material, surface condition and type of contamination.

Wooden decking may benefit from gentle brushing and suitable cleaning solutions, while composite decking should be cleaned according to the manufacturer's recommendations.

Professional assessment can help determine the most appropriate method.

Can you pressure wash wooden decking?

Some wooden decking can be pressure washed using carefully controlled pressure and suitable techniques.

However, excessive pressure can damage timber fibres, cause splintering and leave visible marks.

Gentler cleaning methods may be preferable for delicate or weathered decking.

Can composite decking be pressure washed?

Some composite decking manufacturers permit pressure washing within specified limits.

Others recommend low-pressure rinsing and gentle brushing.

Always follow the manufacturer's instructions.

Does soft washing work on decking?

Soft washing can be effective for removing algae and other organic contamination from compatible decking surfaces.

However, the cleaning solution must be suitable for the specific material and finish.

How do you remove green algae from decking?

Green algae can often be removed using suitable cleaning products, gentle brushing and appropriate rinsing.

The cleaning method should be compatible with the decking material.

How do you clean slippery decking?

Slippery decking caused by algae and moss can often be improved by removing the biological growth.

However, wet decking can remain slippery even after cleaning.

Regular maintenance and suitable slip-resistant measures may be necessary.

Can decking be cleaned without a pressure washer?

Yes.

Many decking surfaces can be cleaned using suitable detergents, soft brushes and low-pressure water.

This may be preferable for delicate timber or certain composite decking products.

Will decking cleaning remove black stains?

Some black stains caused by organic contamination can be removed or reduced through cleaning.

However, staining caused by tannins, metal reactions, weathering or permanent surface damage may require specialist treatment or may not be fully removable.

Does decking cleaning damage wood?

Incorrect cleaning methods can damage wood.

Excessive pressure, abrasive brushing and unsuitable chemicals can affect timber fibres and existing coatings.

Using appropriate cleaning techniques helps reduce these risks.

How often should wooden decking be cleaned?

Many wooden decking areas benefit from a thorough clean approximately once a year.

However, decking in shaded or damp locations may require more frequent maintenance.

Decking can sometimes be cleaned during winter when conditions are suitable.

However, freezing temperatures, icy surfaces and poor drying conditions may make cleaning unsafe or ineffective.

Can decking be cleaned before oiling or staining?

Yes.

Cleaning is often an important preparation stage before applying decking oil, stain or another protective finish.

The decking must be suitable for coating, free from incompatible residues and sufficiently dry before the finish is applied.

Follow the coating manufacturer's preparation instructions.

Will cleaning restore grey decking to its original colour?

Cleaning can remove surface dirt and biological growth, but it may not fully reverse natural timber weathering.

Grey timber may require additional restoration products or surface preparation.

Results depend on the timber species and condition.

Can you remove moss from between decking boards?

Moss can often be removed using careful brushing and suitable cleaning techniques.

It is important to avoid damaging the edges of the decking boards.

How long does decking take to dry after cleaning?

Drying time depends on the decking material, weather conditions, shade, ventilation and moisture levels.

Timber may retain moisture for longer than some composite surfaces.

Decking should be allowed to dry sufficiently before applying oils, stains or protective coatings.

How much does decking cleaning cost in Dorset?

The cost depends on the decking size, material, condition, accessibility and cleaning requirements.
