For routine cleaning of lava stone, always use soft sponges and cloths. For optimal results, we recommend using warm water with a detergent FILAPS87, to be diluted in 1:20 portion in water. Avoid direct contact with containers holding oils or acidic substances.  It is strongly recommended NEVER to use acidic cleaning products or abrasive materials, as these could mar/damage the stone's surface and compromise its natural beauty.
MAINTENANCE OF GLAZED LAVA STONE: The glazing process makes the stone highly resistant to UV rays, water, heat, frost, chemicals, and stains. However, the surface may still become stained. We recommend diluting FILACLEANER® or FILAPS87® in warm water.
