High temperature in the microwave will cause the air inside the eggs to expand, leading to the explosive bursting of the eggs, creating a messy and potentially dangerous situation with the risk of the microwave catching fire. Therefore, it's advisable to refrain from attempting to microwave eggs. Instead, crack the eggs into a bowl, break the yolk, and then microwave to cook thoroughly.
4. Shellfish with hard shells
Shellfish such as crabs, clams, and snails lose their nutritional value and delicious taste when microwaved, releasing unpleasant rubbery odors.
5. Chili peppers
Chili peppers can become extremely hot in the microwave. Opening the microwave door will expose you and those around to a sudden attack of hot, spicy fumes, causing watery eyes and sneezing.
6. Grapes
While many fruits can withstand high temperatures, grapes can ignite and explode if placed in the microwave. Dried grapes, in particular, can catch fire and produce smoke.
7. Nitrate-rich foods
Foods high in nitrates, such as cured pork and smoked meat, should not be microwaved as nitrates can transform into nitrosamines, a substance known to cause cancer, posing health risks for the entire family.
8. Mini thermos or insulated thermos

Mini thermoses, double-walled thermoses, or stainless steel thermoses prevent the hot air from the microwave from coming into contact with the liquid inside, potentially damaging the microwave. If the thermos is made of plastic, it's essential to check whether the material is microwave-safe.
9. Metal utensils
Metal items should be kept far away from the microwave. Microwave radiation cannot penetrate metal, reflecting back into the microwave chamber, heating the surroundings, and leading to fire, microwave damage, and serious harm to those nearby.
Therefore, never place metal bowls, plates, or dishes with metal patterns in the microwave to avoid starting a fire.
10. Various types of fabric towels
If you have the habit of using the microwave to dry or sterilize various fabric towels, including hand towels, tablecloths, and cup liners, you need to stop immediately. This practice can result in fabric ignition or even cause a fire when the temperature becomes excessively high.
