If you want to get rid of the smell of oil smoke in the kitchen, the materials you use are readily available, such as lemon residue, which is a great deodorizer. You can also cut the lemon residue squeezed from drinking black tea, or the lemon that has been forgotten for a long time, into thin slices or small pieces, then put it in a pot and add water to boil it. After boiling, you can continue to add water to boil it. At this time, the smell emitted can not only remove the smell of oil smoke, but also make the air full of pleasant fragrance. Alternatively, you can also prepare a handful of green tea and a flat-bottomed pot. First, heat the pan with a fire, then put the green tea on it and fry it to taste. After a while, the indoor lampblack and odor will be replaced by the fragrance of green tea!
