The soot sponge is produced from foamed latex (natural rubber). The sponge is used for cleaning without water. It is only used dry, whereby it 'absorbs' dust and soot particles. It is therefore good at removing soot particles without the item getting wet. The sponge can easily be cut to a smaller size, making it easier to use in places where there is not much space. In this way, the edges of the sponge can be used a bit like a large eraser.
After use, clean/rinse the sponge with a mild soap. NB! The sponge must not be exposed to sunlight, as this will degrade it.
Where can it be used? The sponge is particularly suitable for sensitive surfaces (e.g. textiles, untreated wood, panels, wallpaper, books, documents, ceilings, etc.) and is often used for soot damage after a fire, soot from candles, etc.
The soot sponge has also been shown to be effective against the blackening phenominom (see below) known as 'witch soot' in homes, which is deposited on walls, ceilings and other surfaces. Black discoloration (witch soot and thermal) These discolorations can occur quickly or after a long time, depending on the type of soot and special conditions in the home. Rapid blackening ("witch soot") occurs in both new construction and older buildings and is often caused by airborne dust deposited by a chemical process on surfaces that do not always form thermal bridges. It often occurs immediately after renovation of a home and more often in autumn than in spring. This probably happens because during spring and summer the heat is shut off and air is vented more. In this way, dust particles and volatile substances are removed from e.g. paints. Slow blackening (thermal) can often be attributed to particle deposition on surfaces with large temperature differences, e.g. on cold bridges, over heat sources or lamps. On walls and ceilings with thermal bridges, particles are deposited as dust figures on the cold areas. They are formed when the temperature difference on surfaces within a short distance is more than 2–3 °C. This occurs, for example, in older brickwork with combined front and back walls, in addition to fixed ties, on cladding panels next to posts and battens, which form a thermal bridge in the construction, at nails or screws in cladding panels.
