Clean the oven spark plugs

You can find a knife or a relatively sharp object, then gently scrape off the oil on the surface of the oven spark plug, and finally wipe the surface of the induction needle with a slight wet wipe of the rag. Note that no matter how to rub, the surface of the induction needle will be black, so the user only needs to be able to clean the surface oil, if it is really impossible to clean up, it is recommended to buy a similar model of induction needle for replacement, or ask a professional to come to the door to replace
