Using this burner cap is easy. Just place it on the burner of your Westinghouse or Chef gas oven or stove. Make sure it fits properly before turning on the gas. When using, keep an eye on the flame to ensure even heating. As for maintenance, after each use, let the burner cap cool down completely. Then, you can use a mild soapy water solution and a soft cloth to clean it. Avoid using abrasive cleaners as they may damage the sintered enamel coating. If you're not sure whether this burner cap suits your model, always provide your model number before purchasing to avoid any compatibility issues.
