How to properly clean the seal of a thermos: a guide to keep it clean and extend its life
The thermos is an indispensable companion in our daily life, providing us with warm or cold drinks, whether in the office, the gym or outdoor adventures. However, the seal of the thermos is the most likely place for dirt and grime to hide. If it is not cleaned regularly, it will not only affect the taste of the drink, but also pose a threat to your health. This article will provide you with the steps and tips to properly clean the seal of the thermos.

Why cleaning the seal is important
The seal is an important part of the thermos, which ensures the seal and insulation effect of the cup. Over time, the seal will accumulate dust, bacteria and mold, which will not only change the taste of the drink, but may also have an impact on your health. Regularly cleaning the seal helps keep the drink hygienic and fresh, while extending the life of the thermos.

The right steps to clean the seal
1. Remove the seal
Before cleaning, you first need to remove the seal from the thermos. Usually, the seal is fixed by twisting or prying. Use non-metallic tools (such as plastic or wooden tools) to pry gently. Avoid using metal tools to avoid damaging the seal.

2. Gentle cleaning
Use a mild detergent and warm water to clean the seal. Avoid using strong chemical cleaners, as they may damage the material of the seal. Soak the seal in warm water, add an appropriate amount of detergent, and gently scrub.

3. Use a soft brush
For stains that are difficult to clean, you can use a soft-bristled toothbrush or a special cup brush to gently scrub. Avoid using a hard-bristled brush or steel wool, as they may scratch the seal.

4. Rinse thoroughly
After cleaning, rinse the seal thoroughly with clean water to ensure that there is no residual detergent. Residual detergent may affect the taste of the drink.

5. Air dry
Place the seal in a ventilated place to air dry naturally, avoid direct sunlight or use high temperature drying, as high temperature may damage the material of the seal.

6. Regular inspection
After each cleaning, check the seal for signs of wear, cracks, or other damage. If the seal is damaged, it should be replaced in time to ensure the sealing and insulation effect of the thermos cup.

Maintenance Tips
Avoid high-temperature sterilization: The seal is usually not heat-resistant, so high-temperature sterilization methods such as boiling or using a sterilizer are not recommended.
Replace regularly: Even if the seal still looks intact, it is recommended to replace it at least once a year to maintain the best sealing effect and hygiene.
Storage precautions: When the thermos is not in use, make sure the seal is completely dry to avoid humid environments that cause mold growth.
By following the steps and tips above, you can ensure that the seal of the thermos is always clean and hygienic, providing the best protection for your drinks. Proper cleaning and maintenance will not only improve the quality of your drinks, but also extend the life of your thermos.
