There are various kinds of kitchen pots, and different materials will produce different pot dirt.
Stainless steel pots
Stainless steel pots are easy to produce black scale and are not easy to clean. If it is black scale inside the pot, we can put clean water in the pot and put a few pieces of pineapple peel. The water should cover the black scale. Cook for about 20 minutes on the fire, let it cool and wash it. The black scale can be removed and restored to brightness. If it is black scale outside the pot, you need to prepare a larger pot. The method is the same as above, just put the small pot with black scale into the big pot and cook it. Note: Stainless steel tableware with wooden or rubber handles should not be steamed in boiling water, because the wooden or rubber handles will be damaged by heat. Smaller yellow marks can be wiped with toothpaste, which is very effective. Wujie powder is also OK, but there will be relatively coarse grinding marks.
Pressure cooker
When dealing with the dirt left on the pressure cooker, you can cut the used toothpaste, keep the toothpaste on it, wipe the surface of the pressure cooker directly with the toothpaste tube, and then rinse the toothpaste and dirt with clean water. Another way is to apply a small amount of vinegar on the stain, wipe it with a cleaning cloth after a while, and then clean it with clean water.
Clay pot
When the clay pot is stained with oil that is difficult to clean, you can use the leftover tea residue to wipe the surface of the clay pot several times to remove the oil stain. When dealing with other dirt, you can pour some rice soup into the pot to soak, then heat it, and then use a brush to clean the dirt in the pot, and then rinse it with clean water.
Aluminum pot
It is easy for aluminum pots to have black scale after being used for a long time. We can use fruits and vegetables to deal with black scale. Lemon, onion, cucumber, apple peel, tomato, potato peel, etc. have some effect. For example, boil water and apple peel together in an aluminum pot, and the black scale is easier to clean. If the aluminum pot is burnt, you can put some onions and water to boil together, which has a certain effect.
Iron pot
Iron pots are more likely to produce moldy odors. We can use leftover tea bags to remove mold. First, evenly apply some salad oil on the inside and outside of the iron pot, then put the iron pot directly on the fire to heat it, and then put a dry tea bag in the pot, so that the mold can be removed. If there is rust in the pot, you can add some water to the iron pot, put some fresh leeks, and press the leeks into the iron pot with a shovel to wipe the bottom of the pot while heating the pot to remove the rust.
