Use more hot water bubbles, add a little vinegar, and boil it in hot water, and it will wash off.
1. Never use a steel ball brush, it will damage the pot. If it is brushed by aluminum pot, it will be bad for you to cook and eat it later. You can use coarse cloth instead of steel balls, or use tomatoes to paste the bottom of the pot. If you cook some tomatoes in the pot, they will naturally fall off.
2. Fruits can also be used. Peel the apples or pears to paste the bottom of the pot. Boil some water with apple peel or pear peel, and then it will be easy to clean. ? Cut a few pieces of oranges into the bottom of the pot and boil them in the pot. If you keep them stuffy for one night, the paste will turn up the next day and it will be easy to remove. I'll give you another secret recipe, so don't tell anyone easily. In summer, pour a little rice into the pot and let it ferment naturally. Two days later, after smelling the sour taste, the hands were ashed.
3. Soak in a high-concentration sodium hydroxide solution (for example, 1g of water and 5g of sodium hydroxide, because it is strongly corrosive, acid alkali resistant gloves must be taken, and it cannot be used for cleaning aluminum products), and then scrape with a steel ball. If you can find "sodium percarbonate or sodium perborate", you can directly pour boiling water, then add boron or carbon percarbonate, soak it in water temperature and then pour it out. The former is to remove burnt oil, and the latter is to remove the yellow color. Brush with a cleaning ball.
