In addition, due to the complex internal structure of the thermos cup, especially there are many groove patterns at the bottle mouth and the lid of the cup, it is easy to hide dirt and shelter evil people without careful cleaning. Clean water can't clean the dirt in the groove in the thermos cup, so it is recommended to carefully clean the dirt in the gap with a cotton swab or brush. Pay special attention to the lid and mouth of the cup, and it is best to clean it after use every day to avoid fouling and bacteria.
Sometimes, the dirt attached to the inner wall contains grease, which is not easy to clean. You can use a soft brush dipped in detergent or baking soda to wash it, and then rinse it with clear water. Do not use stainless steel balls or scouring pads to avoid scratching the intima. ?
Extended data:
If the thermos cup is not cleaned in time or used improperly, there will be a lot of bacteria hidden in it. Careful people will find that there are many sanitary dead ends in the thermos cup, such as the gap between the inner container and the bottle cap. During normal cleaning, it is difficult for hands to touch these places.
The temperature in the thermos cup is suitable and the environment is humid, which is easy to breed all kinds of bacteria. And the oral cavity itself is a "bacteria-carrying" environment. Drinking water and capping the bottle cap many times a day will make the bacteria attached to the mouth of the cup accumulate more and more in the gap of the bottle cap and easily enter with the water. ?
Proper use of thermos bottles should pay attention to the following points:
1, thoroughly clean once a day. This is the fundamental way to prevent odor and stains. When cleaning, you must not simply rinse with water. Pay attention to the cup surface, inner container and bottle cap. ?
2. Wash the liner first, and then wash the bottle cap. Generally speaking, the correct steps are: put a small amount of salt in the bottle, add warm water, shake well and soak for 5~ 10 minutes; Take off the lid of the cup, squeeze some toothpaste on the toothbrush and gently brush the gap of the bottle cap; Rinse the inside and outside of the cup with clean water; Don't cover it immediately after washing, dry it thoroughly before covering it, so as to avoid the stainless steel thermos cup stinking. ?
3. Don't make tea or drink. It is best to use thermos simply for drinking water, and avoid making tea and filling drinks, dairy products or traditional Chinese medicine.
