Practical guide for homeowners, farmers, and commercial businesses.

For many homeowners, a wooden deck is the centerpiece of their garden. Whether it's a cozy barbecue evening, a summer breakfast, or a gathering spot for family and friends, wooden decks create a warm, natural atmosphere. At the same time, however, they are heavily exposed to the elements. Rain, UV radiation, moss, algae, pollen, or soil from gardening work visibly take their toll on the wood over time.

Especially in Bavaria and Swabia, where many terraces are affected by trees, agriculture, or high humidity, many owners regularly ask themselves:

How do you clean a wooden deck properly – without damaging the wood?

In this comprehensive guide, you will learn:

• How to properly clean a wooden deck

• Which tools are suitable for which decks

• Why algae and moss appear

• When a high-pressure cleaner is useful
  

• Why consulting with a local specialist dealer saves money in the long run

Why wooden decks need to be cleaned regularly

Wood is a natural material. While it has a beautiful appearance, it reacts more sensitively to environmental influences than stone or concrete.

Typical dirt on wooden decks:

• Green film from algae

• Moss formation on shaded decks

• Pollen in spring

• Soil and clay from gardening work

• Grease stains from the grill

• Leaf deposits in autumn

• Dark discoloration due to moisture

These problems occur particularly frequently with:

• Terraces in the shade

• Terraces under trees

• Terraces with little sunlight
  

The consequences of insufficient cleaning are:

• slippery surfaces

• faster graying of the wood

• permanent stains

• increased mold and mildew formation

Regular cleaning is therefore an important part of deck maintenance and value preservation.

Cleaning a wooden deck – the most effective methods

Depending on the degree of soiling, there are different cleaning methods.

1. Cleaning with brush and water

For light soiling, a simple mechanical cleaning is often sufficient.

Procedure:

1. Sweep the deck thoroughly with a broom or leaf blower

2. Use warm water with a mild wood cleaner, which is also available in our specialty store!

3. Clean the wood with a brush along the grain

4. Rinse with water afterwards

Advantages:

• Very gentle on the wood

• No aggressive technique

• Ideal for smaller decks

Disadvantages:

• Very time-consuming

• Less effective on stubborn green film

2. Cleaning a wooden deck with a high-pressure cleaner

For heavier dirt or larger deck areas, a high-pressure cleaner is often used.

Professional equipment from STIHL is particularly powerful and versatile.

Typical areas of application:

• Large deck areas

• Commercial properties

• Restaurant terraces

• Municipal outdoor facilities

• Agricultural living areas

Advantages:

• Very high cleaning performance

• Reliably removes algae and moss

• Saves a lot of time on large areas

Important:

For wooden decks, the pressure must not be set too high. Too high pressure can:

• Tear wood fibers

• Damage surfaces

• Cause splintering

Therefore, the water jet should always be directed at a distance and in the direction of the wood grain.

3. Patio cleaner attachments for high-pressure cleaners

For decks, there are special attachments for surface cleaning. An example would be the RA 110 surface cleaner.

Advantages:

• Even cleaning

• Significantly gentler on wood

• Less splashing water

• Faster work

This attachment is particularly worthwhile for larger decks or restaurants.

Typical problems with wooden decks

Many customers repeatedly report the same difficulties.

Green film on wooden decks

Green film is caused by algae and microorganisms.

Causes:

• Moisture

• Little sunlight

• Organic deposits

Green film makes decks extremely slippery and should therefore be removed regularly.

Grayed wood

Wooden decks lose their original color over time.

This is due to:

• UV radiation

• Weather influences

• Lack of care

Thorough cleaning is often the first step before new wood care or oil treatment.

Moss formation

Moss often forms in shaded areas.

Typical spots:

• Terraces under trees

• North sides of buildings

• Terraces near forests

Regular cleaning is particularly important here.

Consultation for larger terraces and commercial properties

For most outdoor areas, individual consultation is advisable; if you are unsure, you can arrange an on-site consultation with us.

This analyzes:

• Size of the deck

• Type of dirt

• Existing water connections

• Optimal equipment choice

This way, the most efficient and economical cleaning solution can be found.
