Using this burner cap is easy. Just place it on the appropriate burner of your Westinghouse or Chef gas stove. Make sure it fits snugly. When using your stove, avoid placing very heavy or sharp - edged objects on the burner cap to prevent damage. After each use, let the burner cap cool down completely. Then, you can clean it with a mild detergent and a soft cloth. Don't use abrasive cleaners as they can scratch the matt finish. Check the burner cap regularly for any signs of wear or damage. If you notice any issues, it might be time to replace it. If you're unsure whether this burner cap fits your model, always provide your model number before making a purchase.
