Using this burner cap is easy. Just place it on the appropriate burner of your Westinghouse or Chef gas stove. When using, make sure the stove is clean and dry to ensure good performance. Avoid using abrasive cleaners as they can damage the sintered enamel coating. After each use, let the burner cap cool down completely before cleaning. You can wipe it with a damp cloth and mild detergent. If there are stubborn stains, soak it in warm, soapy water for a while and then gently scrub. Keep it in a dry place when not in use to prevent rusting. If you're unsure if it fits your stove model, always check with us first by providing your model number.
