When the iron pan rusts, it can be wiped with a cloth dipped in vinegar after heating, which is simple, quick and thorough. Don't wash it too clean after each use, save some oil to prevent rust. You can heat the wok first, then pour in a little oil, wipe it evenly with a shovel, then turn off the fire and rinse it with water the next day. According to the sales staff of ASD kitchen utensils, we should pay attention to the following points when choosing wok.
1, the pan surface should be smooth, but not "smooth as a mirror". Because of the casting process, all iron pots have irregular shallow lines, which is not a problem. 2. Check for defects. There are two kinds of defects: small bumps and pits. The raised part of the small bump is generally iron, which has little effect on the quality of the pot. If the bulge is on the concave surface of the pot, it can be removed with a grinding wheel to avoid blocking the spatula. Small pits are complicated and harmful to the quality of bowls. There are three main situations: trachoma, blowhole and shrinkage cavity. The "three eyes" easily occur in the center of the convex and concave sides of the pot, which is the throat for pouring molten iron. Pay attention to the inspection when buying, because some people fill the pit with graphite, which is not easy for ordinary people to notice, and can only be exposed by brushing with a small brush.
3, the bottom of the pot is commonly known as the bottom of the pot. A cauldron has a bad ass, because fire travels slowly. It takes enthusiasm and time.
4, the pot is thick and thin, and the thinner is better. Some iron pots may be thick on one side and thin on the other, which is caused by the dislocation of models. This pot with uneven thickness is not good. When buying, you can turn the bottom of the pot upside down, put your finger against the concave center of the pot and knock it with a hard object. The louder the pot rings, the greater the vibration, the better. This method can also be used to check whether there are cracks in the pot. Cracks are generally easy to appear at the edge of the pot, because otherwise it is the thinnest.
5. If there are rust spots on the pot, it is not necessarily of poor quality. The brightness and quality of the pot have little effect. Because the substance that makes the pot shine is graphite. The purpose of graphite in casting is to use it as a refractory coating. After the pot is cast, graphite can objectively prevent the pot from rusting. Pots with rust spots indicate a long storage time. The longer the pot is stored, the better, because the internal structure of the pot can be more stable and it is not easy to crack when it is used for the first time.
6. Cast iron pan (also called pan) is often used for "frying" and "branding" without fire, so the bottom of the pan is thicker and the weight can be heavier. Small coup for rust removal and rust prevention: remove rust from radish and potato skin. The kitchen knife is rusty, not only not sharp, but also annoying rust when cutting. Dip the cut potato skin or radish skin with a little fine sand and wipe the knife surface hard, and rust can be easily removed. Rust prevention of tea residue. Iron pots are prone to rust spots when they are wet, and it is difficult to remove them. You can wipe the iron pot with a gauze bag filled with tea residue to prevent the iron pot from rusting. Taomi water is rust-proof. If iron cookers such as kitchen knives, scrapers and iron spoons are cleaned and soaked in high-concentration rice washing water, they can be prevented from quickly producing rust spots, because rice washing water will add a protective film to them. Rust removal of cigarette tin foil. All the bronzes at home have green rust. You can wrap the cigarette in tin foil and wipe it carefully with salt, which will not only remove rust, but also make the cleaned bronze ware as bright as new.
