Using this Westinghouse oven rack is easy. First, make sure your stove is turned off and cooled down. Then, simply place the rack inside the oven in the desired position. When using the air - fryer function, the rack helps to circulate hot air around your food for even cooking. For cleaning, remove the rack from the oven and wash it with warm, soapy water. Avoid using abrasive cleaners as they may damage the rack's surface. Store the rack in a dry place when not in use.
