Removing burnt food is easier to address before the residue hardens. The cited guidance recommends cleaning the wok while it is warm and grease, oil, and food bits remain soft, then using a scrub brush with light yet firm pressure.
When should the wok be cleaned?
Warmth should not be confused with a temperature that is too hot to handle safely. Once the wok is safe to handle, check whether the stuck food has hardened. Cleaning while it remains soft is the condition specifically recommended by the cited guidance.
What brushing technique is recommended?
Use a scrub brush in a circular motion with light yet firm pressure. The source does not specify a soaking time, detergent, water temperature, or separate procedure for residue that has already hardened.
What does the reader still need to confirm?
Before applying any additional treatment, the reader should check the wok’s care instructions, especially if it has a coating or another special finish. Those instructions should take precedence if they differ from general cleaning guidance.
