Wash the pan before the first use with soapy water by hand. Don't put your bakeware to a dishwasher. That will prolong the life of a non-stick coating. Avoid using abrasive cleaning pads or cleansers, and metal utensils. Always allow bakeware to cool before cleaning. Never immerse hot bakeware in cold water for cooling.
Do not use aerosol cooking sprays. They release effectiveness in the longterm because they can build up on non-stick surfaces.
