Before the first use, wash the dish in hot, soapy water, and rinse and dry thoroughly. For most day-to-day cleaning, cool the dish for a few minutes before washing and drying, or wash in the dishwasher, allowing the full cycle to complete.
Never leave a dish fully immersed in water.
For removal of stubborn residues allow the dish to cool, fill with warm, soapy water and allow it to soak for 10 to 20 minutes. Wash in the usual way using a plastic brush or scouring pad if necessary.
