FIRST USE: before use, wash the inside of the item with care, grease evenly with a little oil and dry with some kitchen towel or a soft cloth; repeat this operation every so often. PRECAUTIONS: Always cook over a moderate heat; never overheat the item when empty. Do not allow fatty foods to burn inside the pan. Only use plastic or wooden utensils, not metal ones. WASHING: Leave the item to cool before washing as immersion in water could cause irreparable deformation and ruin the performance of the surface. This item is dishwasher safe; use lowtemperature settings (50° or ECO) and minimum amounts of detergent. Washing by hand with liquid detergent and a soft sponge is the best way to keep this item looking and working at its best. Never wash this item with powder detergents and/or scourers. Spots or stains may form on the item; however these will not affect use or performance in any way. To help prevent the formation of stains, cover the whole bottom of the item with a mix of water and bleach (half and half ), and leave it to act for at least 1 hour. Rinse and then wash thoroughly with hot water and a liquid detergent, then dry before conditioning the surface with a little oil. HANDLES AND LIDS: The steel handles can become hot and therefore, pot holders should be used. Glass lids can withstand sudden thermal changes, but we advise against allowing them to cool suddenly.
