Clean the surface with a vacuum cleaner with a soft nozzle or brush with a soft brush or a dry swab. The surface can be wash in warm water with a natural cleaning detergent (e.g. universal cleaner) if needed. This will form a thin protective and nurturing layer at the surface.
Floors made of vinyl, should be washed with a wrung cloth or swabed once a week - e.g. in universal cleaner. Do not use any other cleaning materials, as they may reduce the anti-slip effect. Please note that soft soap and soap flakes will leave a greasy surface on the vinyl floor. If the vinyl floor has started getting a matt surface, it can be washed with a cleaning detergent. Afterwards the surface must be scrubbed with a sponge and must be wiped with clean water. Finally, wash the floor with a nurturing cleaning detergent that contain wax or polymer.
