Hako Cleanol-K does not have surfactants and is ideally suited for the cleaning of micro-porous surfaces such as marble, marble composite, unglazed floor tiles and anti-slip tiles, amongst others. Dirt should preferably be removed with a scrubber-drier or wet-vacuum machine to make sure the grime is effectively removed from the micro-pores. The product should not be used on floor coverings with a polymer-based protective layer.
