Nowadays, there are more and more types of pots on the market. They are bought and used indiscriminately without maintenance. They will break after a long time. The following editor will introduce several common maintenance methods for pots.

The newly-purchased iron pan should be soaked in salt water first, and then rubbed with some salad oil before it is easy to use. If there is a peculiar smell, cut the ginger into pieces and wipe it off after the pot is hot. Iron pans are easy to rust, so it is not suitable to hold food overnight. Try not to use an iron pan to cook the soup, lest the cooking oil layer on the surface of the iron pan that can protect it from rusting disappears. When brushing the pot, use detergent as little as possible, and then wipe off the water. If there is slight rust, it can be cleaned with vinegar.

According to related reports, the on-glaze color of some low-quality porcelain tableware contains lead. If the temperature is not enough when the porcelain is fired or the glaze ingredients do not meet the standards, more lead may be released during use. Relevant departments have also found that the amount of lead and cadmium dissolved in individual ceramic pots exceeded the standard during random inspections, which would cause heavy metal poisoning. Since the enamel of the casserole contains a small amount of lead (especially the overglaze colored casserole cannot be used), the newly purchased casserole is soaked and boiled in 4% vinegar water. If the inner wall of the casserole is colored, it is not suitable to store wine, vinegar and acidic food. When choosing ceramic tableware, choose one with smooth and flat surface, uniform ceramics and bright color.
