Winco® sheet pans are designed to withstand high oven temperatures during baking, roasting, and broiling, thanks to their thoughtful construction, which may include galvanized wire reinforcement or extra heavy-duty open bead edges. Made from durable 3003 aluminum, these pans are specifically built to maintain their shape, ensuring consistent results in the kitchen. For added longevity, the closed bead pans feature galvanized wire to enhance rust resistance and structural integrity. Cleaning is straightforward; however, it's essential to hand wash these aluminum products, as they are not dishwasher safe. To care for your Winco® sheet pans, always allow them to cool before cleaning. Using warm water, mild soap, and a soft, non-abrasive sponge will help keep your pans in great condition. After washing, dry them thoroughly with a cloth or paper towel to prevent limescale buildup. If you encounter stubborn cooked-on food residue, simply boil the pans in water mixed with vinegar for 4 to 5 minutes to loosen the debris, and then follow up with the washing steps for a pristine finish.
