WASHING: For daily cleaning, use water with pH dish detergent neutral (Ph = 7), avoiding acid products. Always rinse thoroughly to remove the products used for cleaning; dry well with a clean and soft cloth. If the dishwasher does not perform a proper drying, provide manually. PRECAUTIONS: Do not use steel scourers, abrasive sponges and abrasive powders, or steel burnish machines; their use could cause the removal of the PVD layer. Avoid prolonged contact with food products, for example tomato residues, mayonnaise, eggs, coffee, red wine, salt, vinegar, etc. For the restoration of the articles with limestone stains it is possible to use one of the specific products available on the market – appropriately diluted with water.
