Material: Anodized aluminum reinforced coating + aviation aluminum Size: 9.45inch,4mm; 11inch,4mm How to clean after use? The thermal conductive plate is a substitute for the pot, it will leave traces after use and may be difficult to remove. We do not recommend using steel wool or corrosive cleaning agents to scrub! It is recommended that you use the following cleaning methods: Slightly dirty: Just wait for the board to cool down, soak it in hot water overnight, and then wipe it with a soft cloth. Wipe off obvious dirt, leaving a trace without affecting the effect. Slightly dirty: Apply baking soda to the board, moisten it with warm water, and then wrap it in plastic wrap. Wipe with a soft cloth and warm water the next day, if there are slight marks, it will not affect the effect. Severely dirty: Use a neutral pH cleaner to apply on the board, soak in warm water overnight, and then wipe with a soft cloth. If there are a few traces, the effect will not be affected. Pay attention to when using the thermal board? When using a thermal conductive plate, ensure that there is no obstruction around the thermal conductive plate The heat-conducting plate has a strong heat absorption capacity, cooking can be completed on a small fire, saving energy and reducing emissions The use of large fires is easy to cause heat conduction and energy accumulation, so it will also cause some glass to burst. The heat conduction plate itself has the function of collecting energy, so slow cooking at low heat will be more suitable!
