Using this wok burner cap is easy. Just place it on the designated burner of your compatible AEG or Electrolux gas stove. Make sure it fits snugly. When using, always keep an eye on the flame to ensure proper combustion. As for cleaning, let the cap cool down completely. Then, use a mild dish soap and a soft sponge to gently clean the surface. Avoid using abrasive cleaners as they can damage the matt coating. For maintenance, periodically check the cap for any signs of wear or damage. If you notice any issues, replace it promptly to keep your stove working at its best. And remember, if you're unsure about compatibility, check your model number before use.
