Please refer to the relevant technical information in your product’s specifications sheet.

Each item is made smooth and is polished manually in a number of steps and is protected with oil and water repellent products to diminish the absorption of oily substances and to minimise the formation of stains. Ordinary maintenance should be made with a neuter detergent diluted in water, preferably warm. Rinse often the cloth in the detergent solution, squeezing it well afterwards. 

If oil, wine or other liquids fall on the item remove them as soon as possible to avoid leaving the concrete surface in direct contact for prolonged periods of time with liquids, wet cloths or vases in order to avoid the creation of shades in the affected area.
