For best results, cook using low to medium heat, and always add water or oil when heating. Vegetable oil or cooking spray promote better cooking and easier cleaning. Avoid metal utensils, which can scratch or chip the enamel finish. Use heat-resistant silicone, plastic, or wooden utensils only. If necessary, use non-abrasive pads or scrapers to remove food residue. To clean, hand wash the cookware in warm, soapy water, and then rinse and thoroughly hand dry to avoid rusting. To protect the exterior gloss, avoid citrus-based cleaners.
