Clean paved surfaces are not just about aesthetics – they also protect the value of your property. In regions like Swabia, around Rieblingen, Wertingen, or Dillingen, driveways, courtyard paving, and patios are exposed to heavy daily wear and tear: soil from agricultural machinery, moss growth due to moisture, oil stains from vehicles, or stubborn algae deposits.

Many homeowners therefore regularly ask themselves the same question:

How do you clean paving stones properly – without damaging them?

In this comprehensive guide, you will learn:

• Which methods really work

• Which tools are suitable for which surfaces

• Why moss and algae always return

• When a high-pressure cleaner is worthwhile

• Why maintenance and service are crucial

• Why buying from a local specialist dealer is cheaper in the long run

Why paving stones need to be cleaned at all

Paved surfaces appear robust – however, they are actually relatively susceptible to biological deposits and dirt.

Typical problems on paved surfaces:

• Moss between paving joints

• Algae deposits on shady patios

• Oil and grease stains on driveways

• Soil and mud from agricultural machinery

• Tire abrasion on courtyard paving

• Weeds in paving joints

• Green film on concrete paving

Especially in Swabia, paved surfaces are often damp for long periods – an ideal breeding ground for algae and moss.

This leads to several problems:

• slippery surfaces

• damaged paving joints

• permanent dark discoloration

• faster material aging

Regular cleaning therefore significantly extends the lifespan of the paved surface.

Cleaning paving stones – the best methods

There are several effective methods for cleaning paving stones. The right one depends on the type of dirt and the surface.

1. Mechanical cleaning with a brush

For light dirt, a hard brush is often sufficient.

Advantages:

• no chemicals

• cost-effective

• particularly gentle

Suitable for:

• small patio areas

• garden paths

• light algae deposits

Disadvantages:

• very time-consuming

• not very effective for stubborn dirt

2. Cleaning paving stones with a high-pressure cleaner

The most effective method for large areas is a high-pressure cleaner.

Professional devices from STIHL remove even stubborn dirt.

Typical areas of application:

• farm driveways

• agricultural operating areas

• garage driveways

• large patios

• commercial areas
  

Advantages:

• very high cleaning performance

• fast for large areas

• reliably removes moss and algae

Important:

Too much pressure can wash out paving joints. Therefore, the jet should always be guided at a slight angle.

A surface cleaner attachment is particularly recommended – it distributes the pressure evenly and prevents damage.

3. Cleaning paving stones with a surface cleaner

Surface cleaners are special attachments for high-pressure cleaners.

They offer several advantages:

• even cleaning

• no streaks

• significantly faster work

• less splash water

This method is ideal for large courtyards or driveways in agricultural areas.

Common problems with paving cleaning

Many customers report the same difficulties.

Moss always comes back

Moss grows particularly well in:

• shade

• high humidity

• organic deposits

Therefore, in addition to cleaning, regular maintenance is important.

Weeds in paving joints

Weeds grow when soil and seeds collect in the joints.

Solutions:

• regularly scrape out joints

• apply new jointing sand after cleaning

• use special joint brushes

Oil and grease stains

Oil stains often occur on:

• agricultural farms

• garage driveways

• workshop access roads

Here, pre-treatment with an oil stain remover followed by high-pressure cleaning with a surface cleaner attachment helps.

Battery or electric – which devices are suitable for paving cleaning?

High-pressure cleaners and cleaning devices come with two main drive types.

Electric high-pressure cleaners

Ideal for:

• homeowners

• patios

• small driveways

Advantages:

• low maintenance

• immediately ready for use

• No charging times

Disadvantages:

• corded

• limited power

Battery high-pressure cleaners

Increasingly popular in garden applications.

Advantages:

• mobile

• no cable

• flexible to use

Suitable for:

• garden paths

• small patios

• spot cleaning

Disadvantages:

• limited runtime

• lower power

Buyer's Guide: The right high-pressure cleaner for paved surfaces

Several factors should be considered when buying.

Important criteria

• Operating pressure (bar)

• Water flow rate (liters per hour)

• Hose length

• Accessories such as surface cleaners

• Availability of spare parts

• Ease of maintenance

Especially in professional use, the availability of spare parts is crucial, which is almost always guaranteed with our STIHL and Nilfisk devices.

Repair service for high-pressure cleaners and cleaning devices

Like any machine, cleaning devices also require regular maintenance.

Typical workshop work:

• pump repairs

• seal replacement

• hose repairs

• nozzle replacement

• fixing pressure problems

• engine maintenance for petrol-powered devices

Regular inspection prevents costly damage.

Maintenance and inspection – how to extend the lifespan

Many device failures occur due to lack of maintenance.

Important maintenance work:

• clean filters

• check water connections

• inspect hoses

• clean nozzles
  

A professional workshop service ensures that devices run reliably for many years, and this can of course be easily done with us.

Winter service for cleaning devices

Especially in Bavaria, winters with frost pose a major problem for high-pressure cleaners.

If a device is not stored correctly, the pump can freeze and burst, which is why it is extremely important to store your device in a frost-protected environment during winter. If you are unsure whether your device will work reliably in spring, you can of course arrange an inspection appointment with us before the season starts!

On-site consultation for farmers, municipalities, and businesses

For most areas such as:

• agricultural farms

• municipal yards

• municipal facilities

• commercial areas

a consultation with us makes absolute sense. If you are unsure, we can, of course, also arrange an on-site consultation appointment.

This involves analyzing:

• Area size

• Type of contamination

• Water connections

• Necessary equipment

This way, the most economical and powerful solution can be found, so you can keep your surroundings clean!

FAQ – Frequently asked questions about paving cleaning

How often should paving stones be cleaned?

At least once a year – ideally in spring.

More often for heavily used driveways.

Can high-pressure cleaning damage paving?

Yes – if the pressure is too high or directed directly at the joints.

A surface cleaner significantly reduces this risk.

How do you remove moss between paving stones?

Most effectively by:

1. mechanical cleaning

2. high-pressure cleaner

3. re-grouting with jointing sand

What helps against green growth on terraces?

Green growth is caused by algae.

The best remedies are:

• High-pressure cleaning

• Regular maintenance

• Good drainage of the surface

Conclusion: Clean paved surfaces increase the value of your property

Whether it's a terrace, driveway, or commercial area – clean paving stones ensure safety, better aesthetics, and longer durability.

Even more important, however, is the right advice and a reliable service partner.

As a regional specialist dealer, we offer you:

• personal consultation

• professional equipment

• spare parts

• repair service
