CAKE PAN/TIN | 4 INCH | SQUARE | 4 INCH DEEP These solid bottom 4" deep square cake pans feature straight sides, rolled rim, and uniform wall thickness, essential for professional results. Each pan is manufactured with a premium 3003 aluminium and anodized to promote easier clean up, tremendous durability and baking efficiency. Pan Preparation for Professional Results: The professionals tell us unsalted butter with a dusting of flour is all it takes. Shortening or lard can also be used effectively. Bakeware Care and Cleaning: To maintain the beauty and performance of your bakeware, our cleaning recommendation is a simple hand washing or soaking in warm soapy water, followed by a quick rinse and towel or air drying . Do not use bleaches, harsh chemicals, abrasive soaps, wire brushes, scouring sponges, or sharp tools when cleaning as they can damage the surface of your bakeware. Can I put my pan in the dishwasher? Many dishwasher detergents contain aggressive chemicals and phosphates that can dis-colour the baking surface. This can also be true of bleaches, oven cleaners, and other caustic cleaning agents. The beauty of our anodized bakeware is that you just don't need these aggressive chemicals.
