Using this oven rack is simple. Just place it in your Westinghouse or Electrolux oven where you need it. When using, make sure the oven is clean and free of debris to prevent any scratches on the rack. For maintenance, after each use, let the rack cool down completely. Then, you can wash it with mild dish soap and warm water. Avoid using abrasive cleaners as they might damage the rack's surface. If you're still unsure about its compatibility with your oven model, don't hesitate to reach out to us with your model number.
