How to use a newly purchased pot so that it works well and lasts long

How to use a newly bought pot effectively and make it last long? Here's an explanation:

Method One:
If it is a non-stick pan, you can heat the pan until red hot, then pour in boiling water and boil for about 10 minutes. After drying, it can be used.
Method Two:
For a newly bought iron pot with a lot of rust that cannot be used, you can first sand off the rust with sandpaper, wash it twice with clean water, dry it over the fire, then scrub it clean with hot water, and it can be used.
Method Three:
You can also soak the iron pot in rice washing water for several hours, then wash it clean with water. The rust on the iron pot will be removed more thoroughly.
Method Four:
Before using a new pot, you can pour an appropriate amount of vinegar into the heated iron pot, scrub it with a hard brush while heating, then pour out the dirty vinegar and wash it clean with water to remove the new pot's odor.
Method Five:
Buy some fatty pork, cut it into small pieces, heat the iron pot, then put the fatty meat into the pot. Keep the heat low and continuously rub the pot with the fatty meat until the meat is fried dry. This removes the protective film on the iron pot and prevents rust.
Method Six:
Before using a new iron pot, add salt to the pot and slowly stir-fry the salt over low heat until it turns yellow, then add water and oil to the pot and bring to a boil. This removes the new pot's odor and prevents rust.
Method Seven:
Some new pots have an unpleasant rust smell. You can put peeled sweet potato skins into the pot and boil them to remove the rust odor from the iron pot.
