Why shouldn't you rinse an iron wok with water right after cooking?

Do not rinse an iron wok with water immediately after cooking.
Although iron pots are made of iron, they are not indestructible.
Especially after stir-frying at high temperatures, rinsing the pan directly with cold water can cause significant damage to the pan itself.
Some people might want to save time, while others might want to clean the kitchen immediately after cooking.
But no matter the reason, it's wrong to wash the pot directly.
We've all heard of "thermal expansion and contraction." When cooking in an iron wok, the temperature is constantly increased, causing it to expand.
But even after cooking, the pan was still quite hot.
It needs a slow cooling process. If we put it into cold water immediately, it's like going from an expanded state to a contracted state in an emergency.
This feels like riding a roller coaster; an iron pot couldn't withstand it.
If used in this way for a long time, the iron pot will experience a decrease in color, deformation, cracks, and other problems.
A hot pan easily produces steam when it cools down. We've noticed that when a cast iron pan is rinsed with cold water after cooking, it produces a plume of white smoke, which can easily suffocate people.
Furthermore, after long-term damage, the bottom of the iron pot will become thinner, making it difficult to determine which high-temperature washing will cause an explosion, which could cause even greater damage.
We probably never thought about this problem when we were using iron pots.
Doctors and other professionals have previously warned against the mistake of rinsing iron woks immediately after cooking, because scientific experiments have shown that improper rinsing can lead to the growth of large amounts of bacteria in iron woks.
Bacteria have an adaptation period of 4 hours; after 4 hours, they will multiply rapidly in environments with a lot of oil and moisture. Therefore, we recommend washing the iron pot within 4 hours after eating, and not rinsing it directly with cold water.
These bacteria may be invisible to the naked eye, but they are quietly harming the human body.
Bacteria are the root cause of many diseases. Although modern living standards have improved, we are also finding that diseases are affecting younger and younger people.
Many bad habits in our daily lives that we don't notice are quietly eroding our health.
Washing an iron pot is a very ordinary thing in life, and people find it hard to associate it with various diseases.
Hopefully, through today's understanding, we can realize the importance of properly washing iron pots.
After each use of an iron pot, never rush to rinse it. Always wait until the pot has cooled down before cleaning it.
Many people buy the same model of iron wok, but it looks different after using it.
This has puzzled many people: why do some people's iron pots still look brand new after several years of use, while others' pots start to rust after only a short time?
Although iron woks have many advantages, they are also delicate "little princesses" that require daily maintenance.
If not carefully cared for, it will become dilapidated.
