Before you start cleaning, you should make a few preparations. First, remove loose dirt such as leaves and branches with a broom.

Always test these cleaning agents on an inconspicuous area first to ensure that they do not damage the stones.

A high-pressure cleaner is an extremely effective tool for cleaning paving stones. It not only removes dirt, but also moss and weeds from the joints. Make sure you use a surface attachment to clean the stones evenly and prevent damage. For particularly stubborn stains, it can also be helpful to use a special stone cleaner.
Cleaning the joints: removing weeds and moss

Green deposits and lichens: Stubborn soiling
Green deposits and lichens often become stubbornly attached to paving stones. A combination of mechanical cleaning and chemical cleaning agents can help here. Use a brush with hard bristles and a biodegradable cleaning agent. Leave the cleaning agent to work for a few hours and then rinse the surface thoroughly.
Cleaning natural stone and concrete paving
Cleaning natural stone such as granite or basalt requires special care, as these materials are sensitive to cleaners containing acids and surfactants. Water and a soft brush are often the best choice for cleaning natural stone. You can also use stronger cleaning agents on concrete paving, but be careful not to damage the stones.

Sealing paving stones: Protection against future soiling
After thorough cleaning, it is advisable to seal the paving stones. Our sealing (or impregnation) protects the surface from dirt and makes future cleaning easier. Sealed paving stones are easier to clean as dirt and moss do not stick so easily. Make sure you only use high-quality sealing products that are suitable for the material of your paving stones.
How long does a paving stone seal last?
The durability of our paving stone sealant depends on various factors, such as the wear and tear on the surface, the weather conditions and the quality of the sealant used. As a rule, a good sealer can last between 3 and 5 years before it needs to be renewed. Areas that are exposed to heavy vehicle traffic or intense weathering may have a shorter sealant life.
Care after sealing
After sealing your paving stones, maintenance is much easier as dirt, moss and algae no longer adhere so easily. Nevertheless, you should sweep the surface regularly and clean it with clear water if necessary to remove dirt at an early stage. Avoid using aggressive chemical cleaning agents, as these could damage the sealing layer. Gentle cleaning with mild detergents and rinsing with water is usually sufficient to keep the surface clean and well-maintained.
Regular cleaning is the be-all and end-all
If you want to clean your paving stones regularly, you should carry out a thorough cleaning at least once a year. This can be done in spring or fall, depending on when the stones are most dirty. Regular maintenance prevents the ingress of dirt and provides an attractive and clean surface.
