​Remove the black scale from the pressure cooker

People who don’t have a pressure cooker at home know that after using a pressure cooker for a long time, the bottom will be covered with ash. This is because the pressure cooker is a pot that needs to be burned on the fire for a long time. Even our frying pans are like this. There will be a layer of black stuff underneath, which cannot be washed off with simple cleaning. Some people can’t remove it even by sprinkling detergent. It is better to learn these methods to remove it effectively.

The burnt pressure cooker forms scale, which can be scraped with a sharp knife and then scrubbed with a steel wool. There are also 6 ways to clean the bottom of the paste:

1. Tomatoes: Put a few not-so-good tomatoes in the pot and cook them, and they will naturally fall apart.

2. Apple: Boil apple or pear peels in a little water, then wipe them with a rag and they will be easy to clean.

3. Vinegar: Add a little vinegar and boil it with hot water, and it will be easy to wash.

4. Orange: Cut a few slices of orange and put them in a pot to boil. Simmer overnight. The next day, the residue will turn over and can be easily removed.

5. Salt: Dry-burn over low heat for a while, sprinkle salt when smoking, shake for one minute and turn off the heat, then wipe it again, it can be removed very cleanly without leaving any residue or burnt smell.

6. Pineapple: Just add clean water to a larger pot at home, throw in some pineapple peels, and then put all the smaller pots in. Boil for twenty minutes, wait until it cools down and take it out. It will be as bright as new.

6. Soak it in a high-concentration sodium hydroxide aqueous solution (for example, 100 grams of water and 50 grams of sodium hydroxide. Because it is highly corrosive, you must wear acid-resistant and alkali-resistant gloves. It cannot be used to clean aluminum products), and then scrape it with a steel wool.
