Before you bring your outdoor furniture out of hibernation, you should thoroughly clean the patio area. In addition to dirt, moss, algae and lichens as well as chlorophyll-containing microorganisms have accumulated there over the winter, which in the worst case form a green coating on which you can easily slip. The green build-up also damages the floor material in the long term. Before you tackle this build-up, the first step is to sweep the patio. So grab the broom first!
Normally soiled stones and slabs can be cleaned with a street broom, water and biodegradable neutral soap. Sweeping by hand with a broom or brush has proven to be effective. Basic cleaning is carried out in a dry state. To improve the result, you can also clean the surface with water and a little neutral soap after dry cleaning.
For heavier soiling, you should use special cleaning agents. We offer an extensive range of cleaning and care products for paving, slabs and concrete elements. When selecting these products, it is important to consider the type of soiling you want to clean. There are acidic, alkaline and solvent-based cleaning agents. Each of these products is effective in specific areas but unsuitable for others. Here you will find an overview of all GODELMANN cleaning agents.
Please be sure to test all cleaning agents on a concealed or inconspicuous area before using them on the surface. With concrete blocks, there is a risk that the surface may be attacked by acidic cleaning agents, for example.
Please ensure that mechanical cleaning methods are not used in general, or at least not in the first year, as this removes the loose joint material. We generally advise against the use of vacuum sweepers and high-pressure cleaners, including those with so-called "patio nozzles". Not only do both cleaning systems severely damage the joint fillings in unbound construction, the sharp jet of water from the high-pressure cleaner also roughens the stone surface. This can destroy any sealants and impregnations and lead to long-term structural damage to the material.
