Using your Westinghouse or Chef burner cap is easy. Just place it on the burner of your gas oven or stove where it fits. Before using it for the first time, make sure it's clean. When cleaning, use a mild detergent and a soft cloth. Avoid using abrasive cleaners as they can damage the matt coating. After cleaning, dry it thoroughly to prevent rusting. If you're not sure if it fits your model, always check with your model number before purchasing. This burner cap is built to last, but with proper care, it will serve you well for a long time.
