Prior to the first use of your new cast aluminum cookware, wash it in warm, soapy water with ¼ cup of vinegar. Any remaining traces of manufacturing oils will be removed in this process. Then, rinse fully and towel dry.
Condition your cast aluminum cookware before your first use with 1 tsp (5 ml) of vegetable oil. Using a soft cloth, wipe the oil gently around the interior. Be sure to repeat this conditioning step every couple of months, or if food begins to stick to the surface when cooking.
Pro tip: Invisible buildup can occur when nonstick sprays are used on nonstick surfaces. These sprays can impair the nonstick release system, causing food to adhere to the surface. Avoid using nonstick sprays if possible.
